Further, the screen lock permits the user to rearrange the plurality of images into a first arrangement. Then the first arrangement of the plurality of images is compared with a second arrangement previously stored in the electronic device. If the first arrangement matches with the second arrangement, the electronic device is unlocked. However, the screen lock provides limited protection from unauthorized access. The screen lock proves to be ineffective in the case when an unauthorized user in the vicinity of the electronic device watches the user rearranging the plurality of images into the first arrangement. If the unauthorized user has seen the first arrangement of the plurality of images, the unauthorized user may rearrange the plurality of the images into the first arrangement to access the electronic device.

[5] In yet another existing prior art, a screen lock displays a plurality of images to a user. Further, the screen lock permits the user to select a first image from the plurality of images via an input module of an electronic device. The screen lock compares the first image with a second image stored in the electronic device. If the first image matches with the second image, the screen lock unlocks the electronic device. However, the screen lock provides limited protection from unauthorized access. The screen lock proves to be ineffective in the case when an unauthorized user in the vicinity of the electronic device watches the user selecting the first image. If the unauthorized user has watched the user selecting the first image, the unauthorized user is capable of selecting the first image and accessing the electronic device.

In addition, the present invention enables the user to modify the authentication window with random dummy objects before entering a password to unlock the lock-screen. Moreover, the present invention permits the user to generate a self-creation authentication window to unlock the lock-screen. The self-creation authentication is also referred to as real-time authentication window.

[29] FIG. 1 is a block diagram of a system for authenticating a user in an electronic device, in accordance with one embodiment of the present invention. Examples of the electronic device include but are not limited to smart phones, smart televisions, personal computers, tablet computers and smart music systems. The system 100 includes a configuration module 105, an input module 110, a display module 115, an authentication module 125, a storage module 130 and a processor 135.

[30] The system 100 permits the user to configure a plurality of authentication windows. Each authentication window is associated with at least one token and at least one user defined password. Tokens are generated from user defined passwords. The user defined passwords are generated by connecting a first set of objects in the authentication window. Objects are stored in the electronic device in an object storage module 150. Further, the user can download objects from a website. Examples of websites include, but is not limited to a social networking website, an image hosting website and a search engine website. In addition, the user is enabled to use data items stored in the electronic device as objects. Examples of data items in the electronic device include, but is not limited to text, images, videos, computer generated three dimensional models and sounds stored in database of the electronic device.

[31] Each object in the first set of objects are associated with a unique ID based on an attribute of the object. Examples of attributes includes but is not limited to shape, colour, association with sports and association with celebrities. Examples of data related to attributes include but is not limited to “red”, “square”, “Tom”, and “Harry”. Each of the objects are assigned multiple attributes by the user. For example, a red circle is associated with the attributes “red colour” and “circular shape”. It is noted that an attribute is shared by multiple objects. For example, a red circle, image of a red car, and a red triangle share the attribute “red colour”. The user is enabled to edit each of the objects by adding and removing the attributes from the objects. Moreover, the attributes describe the objects. The objects with similar content share common attributes. For example, an image of a dog, a word “dog” and an image of a puppy share the common attribute “dog”. A first object can be represented by a second object if the first object and the second object share common attributes. For example, an image of a red flag can be represented by an image of a red gown. The image of the red flag and the image of the red gown share an attribute “red”. In another example, an image of a cat is represented by a word “cat”. The image of the cat and the word “cat” share an attribute “cat”.

[32] The system 100 permits the user to configure a plurality of authentication windows. The configuration module 105 enables the user to configure one or more authentication windows. Each of the authentication windows is associated with at least one token. Configuration of the authentication windows includes generating tokens for each authentication window. The plurality of authentication windows is stored in an authentication window storage module 165 in the storage module 130.

[33] To configure an authentication window, the configuration module 105 provides the user with a set of options representing a plurality of classes of objects via the display module 115. Examples of classes of objects include but are not limited to cricket, movies, and flowers. Examples of the display module 115 include but are not limited to liquid crystal display screens, light emitting diode display, cathode ray tube displays and plasma displays. The configuration module 105 enables the user to select the class of objects via the input module 110. The input module 110 is also referred to as user interface. Examples of the input module 110 includes but is not limited to touchscreen, microphone, keypad, and camera. The user selects the class of objects by providing inputs via the input module 110. Examples of methods to provide input in the input module 110 include providing haptic input to a touchscreen, providing voice commands to a microphone, inputting data in a keypad and changing eye gaze in front of a camera.

[34] The configuration module 105 creates a layout of objects for the authentication window. The layout of objects contains a plurality of objects belonging to the class of objects selected by the user. In one embodiment of the present invention, the class of objects and the plurality of objects are stored in the object storage module 150 present within the storage module 130. In one embodiment of the present invention, the layout of objects includes the plurality of objects arranged in a grid. The configuration module 105 displays the created layout of objects to the user via the display module 115. Objects in the layout are arranged in at least one of a rectangular arrangement, a circular arrangement, a three dimensional arrangement, and a two dimensional arrangement. The shape of layout include at least one of a rectangular shape, a circular shape and a quadrilateral shape.

[35] In one embodiment of the present invention, the user is enabled to create the objects in the layout of objects rather than using the objects already stored in the electronic device. As a result, the configuration module 105 provides full user intervention in configuring the authentication window. Objects in the layout created by the user includes objects received in the electronic device from a website. Examples of the website include but is not limited to a social networking website, a search engine website, and an image hosting website. In another embodiment of the present invention, the layout includes objects generated from data items stored in the electronic device. Examples of data items in the electronic device include, but are not limited to text, images, videos, computer generated three dimensional models and sounds.

[36] Further, the user configures the user defined password for the authentication window. The user is enabled to select a second set of objects from the layout of objects in a user defined sequence. The user selects the second set of objects via the input module 110.

[37] Data regarding selection of the second set of objects in a user defined sequence are transferred by the input module 110 to the processor 135. The processor 135 includes a listener and controller module 160. The listener and controller module 160 captures data regarding selection of the second set of objects in the user defined sequence and converts the data into event data. The event data includes actions of the user in the input module 110. Examples of the actions of the user in the input module 110 includes but is not limited to single touch, multi touch, swipe, and scroll. The listener and controller module 160 identifies the unique ID of the second set of objects selected from the event data. The unique IDs of objects are stored in the unique ID storage module 145. The unique ID identified is transferred to the configuration module 105.

[38] The configuration module 105 includes a token module 155. The token module 155 generates a token from unique IDs associated with the second set of objects. The token represents the plurality of objects selected in the user defined sequence. The generated token is transferred to the storage module 130. The generated token is stored in a token storage module 120. In one embodiment of the present invention, each authentication window is configured with multiple tokens. Multiple tokens are configured by providing a plurality of user defined passwords. The token storage module 120 stores a plurality of tokens associated with the authentication windows.

[39] Further, the processor 135 generates a configuration file containing configuration information of the authentication window. The configuration information includes objects selected, the event data, and the token. Further, the configuration file includes information regarding essential elements associated with the authentication window. The essential elements are defined as attributes representing the layout created to configure the authentication window. Examples of the essential elements include, but are not limited to shape of the layout, the number of objects in the layout, arrangement of objects in the layout and a common theme of objects in the layout. The common theme is an attribute shared commonly by the objects in the layout. Consider an example wherein an authentication window has a “rectangular” shape with “cricket” as a theme and “bat” and “ball” as objects. It is to be noted that, the shape “rectangular”, the theme “cricket” and the objects “bat” and “ball” are the essential elements.

[40] The configuration file can be transferred into the storage module 130. The storage module 130 includes a configuration file storage module 140. The configuration file is stored in the configuration file storage module 140. The configuration file is transferred from a first electronic device to a second electronic device to implement the authentication window in the second electronic device.

[41] Further, the system 100 authenticates the user with a lock-screen on accessing the electronic device. When the user tries to access the electronic device, the processor 135 displays a plurality of user selectable options to the user via the display module 115. The plurality of user selectable options include a first set of user selectable options representing the plurality of authentication windows and an option for self-creating authentication windows. It is to be noted that the self-creating authentication window is also referred to as real-time authentication window. The plurality of authentication windows is stored in the authentication window storage module 165. The user is enabled to select a user selectable option via the input module 110. The user selects the user selectable option by entering a first input via the input module 110.

[42] In one embodiment of the present invention, the user selects the user selectable option from the first set of user selectable options to select an authentication window.

[43] In another embodiment of the present invention, the authentication window is selected by the electronic device based on profile of the electronic device. Examples of profile include but are not limited to “General”, “Silent”, “Meeting” and “Outdoors”. For example a first authentication window is selected by the electronic device if the profile of the electronic device is “General” and a second authentication window is selected by the electronic device if the profile of the electronic device is “Silent”.

[44] The system 100 provides the user options to modify the selected authentication window. The user can modify the authentication window by inserting dummy objects thereby generating a dynamically generated authentication window. The dummy objects include objects downloaded by the user into the object storage module 150. In addition, the dummy objects include objects generated from data items stored in the electronic device. Examples of data items in the electronic device include, but are not limited to text, images, videos, computer generated three dimensional models and sounds stored in the electronic device. The system 100 permits the user to enter a second input to set number and type of dummy objects to be inserted in the authentication window. In one embodiment of the present invention, the user enters the second input to set number and type of dummy objects to be inserted in the authentication window. In another embodiment of the present invention, the user enters the second input to select dummy objects. In yet another embodiment of the present invention, the second input is assigned by the system 100 by default. It is to be noted that the dummy objects do not form part of the user defined password. However, dummy objects are inserted in the authentication window to confuse unauthorized users in the vicinity of the electronic device. Inserting dummy objects increases the complexity of the dynamically generated authentication window.

[45] The processor 135 generates the dynamically generated authentication window based on the first input and the second input. Tokens and user-defined passwords associated with the authentication window is associated with the dynamically generated authentication window. Further, the dynamically generated authentication window consists of a plurality of objects arranged randomly. The plurality of objects includes the second set of objects and a plurality of dummy objects. It is noted that an object in the second set of objects can be represented by a different object in the dynamically generated authentication window. A first object in the second set of objects is represented by a second object if the first object and the second object share common attributes. In an exemplary illustration of the present invention, an image of a red flag in the second set of objects is represented by an image of a red gown in the dynamically generated authentication window. The image of the red flag and the image of the red gown share an attribute “red”. In another exemplary illustration of the present invention, an image of a dog in the second set of objects is represented by a word “Dog” in the dynamically generated authentication window. The image of the dog and the word “Dog” share an attribute “dog”. As a result, complexity of the dynamically generated authentication window is increased.

[46] In one embodiment of the present invention, the dynamically generated authentication window displays hints for the user defined password associated with the authentication window. In another embodiment of the present invention, objects in the dynamically generated authentication window interact with the user to provide hints for the user defined password associated with the authentication window. Hints assist the user in recollecting the user defined password associated with the authentication window. Examples of hints include but are not limited to textual data, images, patterns, sounds, videos, and interactive computer simulations. In one embodiment of the present invention, hints include words describing objects that make up the password. In another embodiment, hints include images sharing common attributes with the objects that make up the password. In yet another embodiment, hints include verbal instructions to assist the user to recollect the user defined password associated with the authentication window.

[47] Next, the processor 135 enables display of the dynamically generated authentication window on a lock-screen. The user can access the electronic device by providing a third input on the dynamically generated authentication window. The third input is hereinafter referred to as authentication password. The user provides the third input by selecting a third set of objects among the plurality of objects in a user defined sequence. The user selects the third set of objects via the input module 110. Data regarding selection of the third set of objects and the user defined sequence are transferred by the input module 110 to the processor 135. Any change or update in the authentication window is communicated to other modules by the listener and controller module 160. The listener and controller module 160 captures data regarding selection of the third set of objects and the user defined sequence and converts the data into event data. The listener and controller module 160 generates a reference code from the event data. The event data includes actions of the user in the input module 110. Examples of the actions of the user in the input module 110 includes but is not limited to single touch, multi touch, swipe, scroll and key-press. The listener and controller module 160 detect user input and provide basic shapes, objects, and count. In addition, the listener and controller module 160 updates the authentication window when user provides inputs regarding user preferences.

[48] Another objective of the listener and controller module 160 is to transfer the reference code to the authentication module 125. The authentication module 125 authenticates the user by comparing the reference code with a token of the authentication window. If the reference code matches the token, then the authentication password is valid. If the authentication password is valid, the lock-screen is unlocked. If the authentication password is invalid, access is denied to the user.

[49] In one embodiment of the present invention, while unlocking, the user can select an option to generate a self-creation authentication window. With self-creation feature, the system 100 enables the user to configure a self-creation authentication window. The self-creation authentication window is also referred to as real-time authentication window since the authentication window is created in real-time. To generate the self-creation authentication window, the system 100 enables the user to create a layout of objects first. The objects can be selected from pre-existing objects that are stored in the electronic device, or from a website, or from data items stored in the electronic device. The website can be a social networking website, a search engine website, or an image hosting website. Examples of data items in the electronic device include, but are not limited to text, images, videos, computer generated three dimensional models and sounds.

[50] Upon creation of the self-creation authentication window, a step of comparison is performed by the system 100. The self-creation authentication window is compared with an existing authentication window stored in the authentication window storage module 165. The comparison of the authentication windows can be based on any one of the attributes or essential elements like shape, arrangement, or theme of the objects. The comparison of the authentication windows can also be performed based on layout of objects.

[51] Further, if there is a match between the authentication windows, then the user enters a password. Then the passwords of the authentication windows are compared. If there is a match between the passwords of the authentication windows, then the electronic device is unlocked.

[52] In one embodiment, the step of comparison of the authentication windows as well as the step of comparison of the passwords of the authentication windows is performed in parallel and the result of the comparison is displayed to the user. The user is allowed to take a corrective step in case any one of the comparisons do not give a desired match.

[53] FIG. 2 is a flowchart illustrating steps of configuration of a plurality of authentication windows, in accordance with one embodiment of the present invention. The flowchart begins at step 205.

[54] At step 210, a configuration module in the present invention enables display of a plurality of classes of objects. The configuration module enables the user to select a class of objects from the plurality of classes of objects. Examples of classes of objects include but are not limited to cricket, movies, and flowers.

[55] At step 215, the user selects a class of objects for configuring the authentication window.

[56] At step 220, the configuration module creates a layout of objects by selecting a plurality of objects belonging to the class selected by the user. Further, the configuration module displays the created layout of objects to the user. In the layout of objects the plurality of objects can be arranged in a specific order. Examples of the arrangement include but is not limited to a circular arrangement, a rectangular arrangement, a two dimensional arrangement and a three dimensional arrangement.

[57] In one embodiment of the present invention, the user is enabled to create objects in the layout of objects. As a result, the configuration module provides full user intervention in configuring the authentication window. The objects in the layout created by the user includes objects received in the electronic device from a website. Examples of the website include but is not limited to a social networking website, a search engine website, and an image hosting website. In another embodiment of the present invention, the objects created by the user includes objects generated from data items stored in the electronic device. Examples of data items in the electronic device include, but are not limited to text, images, videos, computer generated three dimensional models and sounds.

[58] At step 225, the user selects the first set of objects in a user defined sequence via an input module. Data regarding selection of the first set of objects and the user defined sequence are transferred by the input module to a processor. The processor includes a listener and controller module. A listener of the listener and controller module captures data regarding selection of the first set of objects and the user defined sequence and converts the data into event data. The event data includes actions of the user in the input module. Examples of the actions of the user in the input module include but are not limited to single touch, multi touch, swipe, and scroll. A controller of the listener and controller module identifies the unique ID of the objects from the event data. The unique IDs of the objects are transferred to the configuration module.

[59] At step 230, a token module in the configuration module generates a token from unique IDs associated with the first set of objects. The token represents the plurality of objects selected in the user defined sequence. It is noted that order of occurrence of steps 210, 215, 220, 225, and 230 is not restricted to the order described in the present disclosure. For example, step 220 can be performed before step 210.

[60] At step 235, the generated token is stored in a token storage module. The token storage module is in the storage module of the electronic device.

[61] At step 240, the configuration module provides the user with an option for creating another authentication window. If the user wants to configure another authentication window, step 210 is performed. If the user decides to stop configuring authentication windows, step 245 is performed.

[62] The flowchart ends at step 245.

[63] FIG. 3 is a flowchart illustrating steps to unlock a lock-screen, in accordance with one embodiment of the present invention. The flowchart begins at step 305.

[64] At step 310, a processor displays a plurality of user selectable options via a display module. The plurality of user selectable options include a first set of user selectable options representing a plurality of authentication windows and an option self-creation feature. The user is enabled to select a user selectable option via an input module.

[65] At step 315, the user selects the user selectable option by inputting a first input to the input module.

[66] At step 320, the processor checks if the user has opted self-creation by selecting the option for self-creation feature. If the user selects the option for the self-creation feature, step 325 is performed. If the user selects the user selectable option from the first set of user selectable options, step 345 is performed. The user selects the first set of user selectable options to select an authentication window from the plurality of authentication windows.

[67] At step 325, with self-creation feature, the processor enables the user to generate a self-creation authentication window. To generate the self-creation authentication window, the processor enables the user to create a layout of objects. The user creates the layout by at least one of selecting the objects already stored in the electronic device, selecting objects received in the electronic device from a website and selecting objects generated from data items stored in the electronic device. The processor generates the self-creation authentication window by arranging the plurality of selected objects. Further, the processor compares the self-creation authentication window with one or more authentication windows stored in an authentication window storage module of the electronic device. The processor compares essential elements of the self-creation authentication window with essential elements of the authentication windows stored in the electronic device. If the self-authentication window matches with at least one of authentication windows stored in the electronic device, step 330 is performed. If the self-creation authentication window fails to match with at least one authentication window stored in the electronic device, access is denied to the user.

[68] At step 330, the processor presents the self-creation authentication window on the lock-screen.

[69] At step 335, the user enters an authentication password in the self-creation authentication window. The processor receives the authentication password.

[70] At step 340, the electronic device is unlocked if the authentication password is valid. An authentication module authenticates the user by comparing the reference code with tokens associated with each authentication window. If the reference code matches a token associated with one of the authentication windows, then the authentication password is valid. If the authentication password is valid, the lock-screen is unlocked. If the authentication password is invalid, access is denied to the user.

[71] At step 345, the processor provides options to modify the authentication window if the user selects the first set of user selectable options at step 320. The user modifies the authentication window by inserting dummy objects. In one embodiment of the present invention, the user can set number and type of dummy objects to be inserted in the authentication window. In another embodiment of the present invention, the user is enabled to select dummy objects. In yet another embodiment of the present invention, the authentication window is modified by applying a default configuration, wherein the default configuration comprises a predetermined type of dummy objects and a predetermined number of dummy objects. The dummy objects are inserted in the authentication window to confuse unauthorized users in the vicinity of the electronic device. The user can select the number and type of the dummy objects by entering a second input to the input module. The processor generates a dynamically generated authentication window based on the first input and the second input. The system performs step 350 after step 345.

[72] At step 350, the processor presents the dynamically generated authentication window on the lock-screen.

[73] At step 355, the user enters an authentication password in the dynamically generated authentication window. The processor receives the authentication password.

[74] At step 360, the electronic device is unlocked if the authentication password is valid. The processor generates a reference code from the authentication password. Further, the processor accesses a token associated with the dynamically generated authentication window. The token is accessed from a token storage module. The processor compares the reference code with the token. If the reference code matches with the token, the authentication password is valid. If the authentication password is valid, the user is authenticated and the electronic device is unlocked. If the authentication password is invalid, access is denied to the user.

[75] The flowchart ends at step 365.

[76] FIG. 4 is a flowchart illustrating steps to generate a self-creation authentication window, in accordance with one embodiment of the present invention. The flowchart begins at step 405.

[77] At step 410, a system receives a first input from a user. The user selects complexity of the self-creation authentication window by providing the first input. In one embodiment of the present invention, the complexity of the self-creation authentication window signifies number of objects in the self-creation authentication window. Hence, the first input is the number of objects in the self-creation authentication window. In another embodiment of the present invention, the complexity of the self-creation authentication window indicates type of objects in the self-creation authentication window. Hence, the first input decides the type of the objects in the self-creation authentication window.

[78] At step 415, the user selects a plurality of objects to configure the self-creation authentication window. In one embodiment of the present invention, the user is enabled to select the objects already stored in the electronic device. In another embodiment, the user is enabled to select the objects from a website. Examples of the website include but is not limited to a social networking website, a search engine website, and an image hosting website. In another embodiment of the present invention, the user is enabled to select objects generated from data items stored in the electronic device. Examples of data items in the electronic device include, but are not limited to text, images, videos, computer generated three dimensional models and sounds.

[79] At step 420, the user creates a layout of objects with the plurality of objects selected to configure the self-creation authentication window.

[80] At step 425, the system generates the self-creation authentication window by arranging the plurality of objects. It is noted that order of occurrence of steps 410, 415, and 420 is not restricted to the order described in the present disclosure. For example, step 420 can be performed before step 410.

[81] The flowchart ends at step 430.

[82] FIG. 5 is a flowchart illustrating a method of authenticating a user, in accordance with one embodiment of the present invention. The flowchart starts at step 505.

[83] At step 510, a lock-screen receives an input from the user. A plurality of user selectable options are presented to the user on the lock screen. The plurality of user selectable options represents a plurality of authentication windows. The user is enabled to select an authentication window via a user interface. The user selects an authentication window by entering the input. The input received from the user indicates the authentication window to be displayed on the lock-screen.

[84] At step 515, the lock-screen provides the user with an option to modify the authentication window with random dummy objects. The user can set number and type of dummy objects to be inserted in the authentication window. In one embodiment of the present invention, the user can set number and type of dummy objects to be inserted in the authentication window. In another embodiment of the present invention, the user is enabled to select dummy objects. In yet another embodiment of the present invention, a pre-set type and pre-set number of dummy objects is assigned by default. The dummy objects are inserted in the authentication window to confuse unauthorized users in the vicinity of the electronic device.

[85] At step 520, the lock-screen displays a dynamically generated authentication window. The dynamically generated authentication window is the modified authentication window. The user enters an authentication password in the dynamically generated authentication window.

[86] At step 525, the lock-screen authenticates the user by validating authentication password entered by the user. The lock-screen generates a reference code from the authentication password. The reference code is compared with a token associated with the authentication window to check the validity. If the reference code matches with the token, the authentication password is valid. If the authentication password is valid the user is authenticated.

[87] The flowchart ends at step 530.

[88] FIG. 6 is a flowchart illustrating a method of authenticating a user, in accordance with another embodiment of the present invention. The flowchart starts at step 605.

[89] At step 610, a configuration module enables the user to configure one or more authentication windows.

[90] Steps 615, 620, 625, and 630 are the steps involved in authenticating the user and thereby unlocking a lock-screen.

[91] At step 615, a lock-screen receives an input from the user. A plurality of user selectable options are presented to the user on the lock screen. The plurality of user selectable options represents a plurality of authentication windows. The user is enabled to select an authentication window via a user interface. The user selects an authentication window by entering the input. The input received from the user indicates the authentication window to be displayed on the lock-screen.

[92] At step 620, the lock-screen provides the user with an option to modify the authentication window with random dummy objects. In one embodiment of the present invention, the user can set number and type of dummy objects to be inserted in the authentication window. In another embodiment of the present invention, the user is enabled to select dummy objects. In yet another embodiment of the present invention, a pre-set type and a pre-set number of dummy objects is assigned by default. The dummy objects are inserted in the authentication window to confuse unauthorized users in the vicinity of the electronic device.

[93] At step 625, the lock-screen displays a dynamically generated authentication window. The dynamically generated authentication window is the modified authentication window. The user enters an authentication password in the dynamically generated authentication window.

[94] At step 630, the lock-screen authenticates the user by validating authentication password entered by the user. The lock-screen generates a reference code from the authentication password. The reference code is compared with a token associated with the authentication window to check the validity. If the reference code matches with the token, the authentication password is valid. If the authentication password is valid the user is authenticated.
