Description:Field of the Invention

[0001] The present invention relates to a system for conducting examinations. More particularly, the present invention relates to a system and method for online submission and evaluation of answer sheet.

Background of the Invention

[0002] Online examinations are increasingly adopted in educational and professional settings due to their flexibility, scalability, and accessibility. However, conducting subjective exams online presents unique challenges. Unlike objective assessments, subjective exams often require handwritten responses, including mathematical derivations, diagrams, or detailed essays. Existing systems typically rely on typed answers or allow image uploads of handwritten responses but fail to integrate tools for real-time monitoring and robust mechanisms to maintain exam integrity. This gap leads to issues in preventing cheating, streamlining evaluations, and ensuring consistent and transparent grading.

[0003] One significant limitation of current systems is the lack of real-time monitoring. Students are often left unsupervised during online exams, creating opportunities for unauthorized assistance or dishonest practices. Current platforms do not use advanced technologies such as front and back cameras or microphones to effectively monitor students. Furthermore, there are no efficient mechanisms to detect anomalies like blurry faces, multiple faces, or whispering during the examination. This absence of proactive cheating detection tools undermines the credibility of the assessment process.

[0004] Another major drawback is the lack of safeguards against students searching for answers online. Most existing systems allow students to access web browsers during exams, enabling them to cheat by looking up answers or collaborating with others. This creates a significant loophole in maintaining exam integrity.

[0005] Evaluators also face numerous challenges with existing systems when it comes to processing and grading subjective answers. Comparing physical answer sheets with their uploaded digital versions is often manual, time-consuming, and prone to errors. Current systems lack the tools to facilitate seamless evaluation or provide evaluators with the ability to compare digital and physical copies side by side. Moreover, answer sheet distribution among evaluators is often disorganized, leading to inconsistencies in grading and delays in providing feedback.

[0006] From a technical standpoint, most platforms fail to ensure that students meet basic technical prerequisites before starting the exam. For example, there are no checks for sufficient internet speed, adequate battery levels, or properly functioning cameras and microphones. As a result, technical disruptions frequently occur, causing inconvenience for both students and evaluators and potentially compromising the examination process.

[0007] Therefore, there is a need for a system and method for online submission and evaluation of answers that overcomes some or all the problems of the existing prior art.

Objects of the Invention

[0008] An object of the present invention is to provide a system and method for online submission and evaluation of answer sheet.

[0009] Another object of the present invention is to provide a system and method for online submission and evaluation of answers sheet that provides live proctoring of the students.

The proctor may view images captured by the front camera and screenshots captured by the virtual camera and listen to audio recordings from the microphone, ensuring adherence to examination rules. Additionally, the system integrates a "restricted browsing mode," which blocks internet browsing on the first electronic devices to prevent online searches during the examination.

[0014] The examination module may generate questions in real time upon receiving a command from the proctor. Students may access the questions sequentially via the first electronic devices, complete their responses on the physical answer sheets, and upload digital images of these physical answers at once to the examination module. The proctor may retrieve the uploaded answer sheets from the central database, compare them with the submitted physical answer sheets, and evaluate the answers while identifying any discrepancies or instances of cheating.

[0015] In an aspect of the present invention, the examination module may analyse the student images, screenshots, and audio recordings in real-time and detect evidence, such as blurry faces, no faces, multiple faces, multiple voices, or whispering and alike within a captured student images and recorded audio of the student during the examination and may send alerts to the proctor.

[0016] In another aspect of the present invention, the examination module may identify violations such as undetected faces, multiple faces, or blank images during the exam, the violations are recorded in the secondary database along with webcam images, recordings, and screenshots from the first electronic device, for live proctoring by the proctor and post exam analysis by the evaluator.

[0017] In another aspect of the present invention, the proctor monitors the students through the administrator interface module which may enable the proctor to analyse the student images, screenshots, audio recordings, and alerts from the examination module during and after the examination and prevent or identify cheating or discrepancies.

[0018] In another aspect of the present invention, the front camera may capture the student's movement during the examination at a predetermined time gap, and the captured images of the student are stored in the central database for post-exam analysis.

[0019] In another aspect of the present invention, the microphone may be ON during the examination, and record the audio of the student, and the recordings are stored in the central database for live proctoring by the proctor and post-exam analysis by the evaluator.

[0020] In another aspect of the present invention, the virtual camera may capture the screenshot of the first electronic device, and captured screenshots are stored in the central database for live proctoring by the proctor and post exam analysis by the evaluator.

[0021] In another aspect of the present invention, the restricted browsing mode may be integrated within the examination module, during the examination restricted browsing mode blocks any web browser within the first electronic device to prevent the student from searching for answers online.

[0022] In another aspect of the present invention, the examination module may grant access to the questions only if the front camera and microphone are working, the first electronic device has a minimum internet speed of 512 kbps, and the battery level is above 90%.

[0023] In another aspect of the present invention, the examination module may create a plurality type of questions formats including multiple choice, true/false, fill-in-the-blanks, and essay-style questions, as per the commands of the proctor.

[0024] According to the present invention, a method for online submission and evaluation of answer sheet begins with creating question banks and storing them in a central database on a server. The process continues by generating question based on commands from a proctor and importing questions from the central database. Before granting access to the exam questions, the system verifies the functionality of the front camera and microphone of a first electronic device.

[0025] A restricted browsing mode is implemented on the first electronic device to block internet browsing and prevent students from searching online during the examination. The system facilitates live proctoring by utilizing the front camera and microphone to capture student activity. Images and audio recordings are displayed on the administrator interface module, enabling the detection and prevention of suspicious behaviours during and after the examination.

[0026] Students access the questions on the first electronic devices and submit a digital answer online via the student interface module. The process involves capturing images of the physical answers using the back camera of the first electronic device. The evaluator retrieves the digital answers through an administrator interface module on a second electronic device for evaluation. The digital answers from the central database may compared with the physical answer sheet submitted by the student to identify any discrepancies or instances of cheating, ensuring transparency and accuracy in the evaluation process.

The second electronic device (120) may be laptops/desktops, tablets or smartphones, and the like.

[0038] The examination module (102) is installed on the first electronic device (110) and second electronic device (120). The examination module (102) includes a student interface module (102a) and an administrator interface module (102b). The student interface module (102a) enables the student to interact with the examination module (102). The administrator interface module (102a) allows the proctor to interact with the examination module (102). The student can access the student interface module (102a) of the examination module (102) by providing student credentials such as ID number, name, department, subject, and like. The proctor accesses the administrator interface module (102b) of the examination module (102) by providing the login ID and password. It is obvious for a person skilled in the art to create a system having two interface modules to provide two different sets of functionalities for two different authorities.

[0039] The first electronic device (110) equipped with the student interface module (102a) allows students to input their details, such as name or registration information, and provides access to the examination module (102). The student gets access to a question within the student interface module (102a) upon getting a command from the proctor. The first electronic device (110) allows the students to attempt the examination and write the descriptive answer on a physical answer sheet (Not shown). After writing the answers the student submits a digital answer (Not shown) in the examination module (102) by capturing the image of the physical answer sheet through a back camera (116) of the first electronic device (110). The first electronic device (110) includes a front camera (114) which allows the examination module (102) to capture the visuals and movement of the student during examination. The examination module (102) records the audio of the student through a microphone (112) and a virtual camera (118) is configured within the first electronic device (110) to take a screenshot of the first electronic device screen (not shown). In the present embodiment, the first electronic device (110) is a mobile phone. It is obvious that the person skilled in the art to use any electronic device that can capture student visuals and takes screenshots and record audio of the student during examination.

[0040] For example, when the student starts the examination by providing candidature details through the student interface module (102a) and activates the web camera (116), microphone (112), and virtual camera (114). The examination module (102) will show each question at a time through the student interface module (102a) of the first electronic device (110) upon getting the command from the proctor. The student will get each question at a time on the first electronic device (110) and write the answer at a time on the physical answer sheet. After writing each answer to the question the student captures the image of the physical answer sheet with the back camera (116) and uploads the image of the physical answer sheet on the examination module (102). At the same time, the examination module (102) captures the screenshot of the screen of the first electronic device (110). Further, the examination module (102) captures the images of the student through the front camera (114) while the student uploads the image of the physical answer sheet and records the audio of the student continuously during the examination. In the present invention, the timing for capturing the student's visual/images through the front camera (114) same as when the student submits/uploads the physical answer sheet. In another embodiment, the timing may be 4 seconds or 3 seconds per image. It is obvious for the person skilled in the art to set any time or no time duration between each image captured by the front camera (114).

[0041] The second electronic device (120) is configured with the administrator interface module (102b). The administrator interface module (102b) connects to the student interface module (102a) through the examination module (102) which enables the proctor to monitor the student during the examination. In the present embodiment, the second electronic device (120) is a computer. In an embodiment, the evaluator may be using a laptop as the second electronic device (120). It is obvious for the person skilled in the art to use any device as the second electronic device (120) with the configuration of the administrator interface module (102b).

[0042] For example, when the student begins the examination by entering credential details in the student interface module (102a) the front camera (114), microphone (112), and virtual camera (118) are activated. The examination module (102) displays one question at a time on the student interface module (102a) upon receiving the command from the proctor. The student writes answers on the physical answer sheet and, after completing each question, captures the answer sheet using the back camera (116) to upload it as the digital answers. The examination module (102) simultaneously captures screen screenshots, and images of the student via the front camera (114), and continuously records audio through the microphone (112). In real-time the proctor can access the administrator interface module (102b) through the second electronic device (120) and monitor the activities of each student at the same time to prevent discrepancies and inconsistencies during the examination. In the present embodiment, the examination module (102) allows the proctor to monitor each student at a time through the second electric device (120).

[0043] In an embodiment, the examination module (102) may display the real-time movement of multiple students on the second electronic device (120) to allow the proctor to monitor multiple students at the same time. It is obvious for the persons skilled in the art to configure the administrator interface module (102b) with features to monitor multiple students during the examination.

[0044] The system (100) includes a server (130) having an interface module (132), the interface module (132) is connected to the student interface module (102a) and the administrator interface module (102b). The server (130) includes a central database (134) to store the examination data from the first electronic device (110). The central database (132) stores the digital answers given by the students through the first electronic device (110), the images of the student captured by the front camera (114), audio recordings, and the screenshot of the first electronic device (110) captured by the virtual camera (118). As soon as the student starts the examination process, the examination module (102) starts to collect the examination data from the first electronic device (110), such as when the student uploads the digital answer sheets in the student interface module (102a), the digital answer will be stored in the central database (134) and at the same time the screenshot of the first electronic device (110) and captured photos of the student, and recorded audio of the student from the front camera (114) and the microphone (112) will be store in the central database (134).

[0045] The central database (134) further encrypts the examination data received from the first electronic device (110) to prevent data tampering during and after the examination. The examination module (102) enables the proctor to access the examination data within the central database (134) of the server (130) through the administrator interface module (102b) during and after the examination.

[0046] The examination module (102) includes a question bank created by the proctor. The question bank includes a plurality of questions related to the predetermined subject with different marks weightage. The examination module (102) creates/generates questions through the question bank in real time upon getting a command from the proctor. In the present embodiment, the examination module (102) creates a descriptive question. In another embodiment, the examination module may be created/generate different formats of the questions including multiple choice, true/false, fill in the blanks, and essay-style questions, as per the commands of the proctor. It is obvious for a person skilled in the art to generate/create the question paper in any format.

[0047] Once the questions are created/generated the examination module (102) enables the student to proceed with the examination only after verifying the presence and functionality of the front camera (114), virtual camera (118), and microphone (112) and a minimum internet speed of 512 kbps, and the battery level is above 90% within the first electronic device (110). In case any feature from the front camera (114), virtual camera (118), or microphone (112) does not work, the examination module (102) will not allow the student to go ahead with the examination, to examine without any loophole for cheating for the student.

[0048] The examination module (102) is configured with a restricted browsing mode (Not Shown). The restricted browsing mode prevents the student from searching online during the examination. The restricted browsing mode is turned ON as soon as the evaluator grants the student access to the question paper. During the examination, for example, when the student tries to search for the answer by opening any browser on the first electronic device (110), the restricted browsing mode will block the student from accessing any browser and send alerts to the administrator interface module (102b) in real time.

[0049] In an embodiment, the examination module (102) is accessed by the student in the mobile application, when the examination starts upon getting access to the question paper, the restricted browsing mode also activates. If the student tries to open any browser within the first electronic device (110) during the examination, the restricted browsing mode will restrict the student from opening any other application within the first electronic device (110) when the examination module is ON, and at the same time the examination module will alert the administrator interface module (102b).

[0050] In another embodiment, the student may be using a laptop as the first electronic device (110) and access the examination module (102) through a web application, the restricted browsing mode will prevent the student from opening new tabs within the first electronic device (110) if the student tries to search for the answer by opening new tab within the browser, and send the alert to the administrator interface module (102b). It is obvious that the persons skilled in the art of configuring the restricted browsing mode within the examination module (102) in any way to prevent the student from cheating by searching for answers during the examination.

[0051] During and after the examination, the examination module (102) analyses the captured images of the student, screenshots, and audio recordings from the first electronic device (110) and identifies violations. The violations are recorded in the central database (134) along with images, recordings, and screenshots from the first electronic device (110), for detailed post-exam analysis.

[0052] The examination module (102) enables an evaluator to retrieve the digital answers uploaded by the student along with the captured examination data to evaluate and identify discrepancies and inconsistencies after the examination. The process of the evaluation involves comparing the digital answers stored in the central database (134) with the physical answer sheet along with each screenshot of that first electronic device, photos of the student captured by the front camera (114), and the recording of the student at the time when the student uploaded the answer if required, to evaluate and detect any discrepancies and inconsistencies or data tempering during the examination.

[0053] For example, when the student starts the examination, the examination module (102) will start to collect data during the examination, such as screenshots, images, and voice recordings. During the examination, the examination module (102) monitors the receiving examination data from the first electronic device (110) and detects any violations within the captured images of the student, such as blurry images, no face, multiple faces, and the like. The examination module (102) detects any violations within the recorded audio of the student during the examination such, as multiple voices, voices when the student's mouth not moving, whispering, and like. Further, the examination module (102) enables the evaluator to get access to the examination data including images, screenshots, and audio recordings, the digital answers, and the physical answer sheet. The evaluator if required compares the submitted digital answers from the central database (134) and the physical answer sheet along with screenshots of the first electronic device (110) stored in the central database (134) to evaluate and detect any cheating or discrepancies or data tempering during the examination. It is obvious for the person skilled in the art to configure the examination module (102) with any feature to detect and alert the violations.

[0054] Further, the examination module (102) generates and organizes collage and video files daily using the examination data from individual students. The examination module (102) retrieves data from the central database (134) of each student, combines all the data individually, and makes college and video files of each student.

[0055] Further, the examination module (102) enables the evaluator to retrieve and analyse examination data such as digital answers, collages, and video files from the first electronic device (110) stored in the central database (134) using the student credentials such as identification number, exam location, and the credentials of the students and the like.

[0056] For example, when the student completes the examination, all the examination data during the examination are stored in the central database (134). The evaluator can access the examination data through the administrator interface module (102b). The evaluator can retrieve each student's data within the server (130) by filtering the name, ID number, exam location, photo of the student, date of the examination, and like. The evaluator then analyses the searched data of the student to evaluate the answers and to detect violations or data tempering. Upon detecting the violation, the evaluator can disqualify the student.

[0057] Referring now to figure 2, a method (200) for digital submission and onscreen evaluation of subjective answers in accordance with the present invention is illustrated. The method (200) is described in conjunction with the system for digital submission and onscreen evaluation of subjective answers described in the above paragraphs.

[0058] The method (200) starts at step 210.

[0059] At step 220, a proctor creates the question bank within an examination module (102) and stores the question bank (not shown) within a central database (134) of a server (130). The question bank includes a plurality of questions related to the predetermined subject with different marks and weightage.

[0060] At step 230, the examination module (102) generates a question upon getting a command from a proctor by importing questions from the central database (134). The examination module (102) generates/creates questions in different formats including multiple choice, true/false, fill-in-the-blanks, and essay-style questions, as per the commands of the proctor.

[0061] At step 240, the examination module (102) verifies the working of a front camera (114) and a microphone (112) of a first electronic device (110) and grants access to the questions. If the examination module (102) finds any problems with the front camera (114) or microphone (112), then the examination module (102) will prevent the student from taking the examination.

[0062] At step 250, the examination module (102) implements a restricted browsing mode within the first electronic device (110) once the student accesses the questions, to prevent the student from searching online during the examination.

[0063] At step 260, the examination module (102) enables live proctoring through the front camera (114), a virtual camera (118), and a microphone (112) of the first electronic device (110), and displays images, screenshots, and audio recordings on the administrator interface module (102b) to detect any cheating or discrepancies or data tempering during and after the exams. The proctor monitors the student during the examination, the examination module (102) displays captured images from the front camera (114), screenshots from the virtual camera (118), and the audio recording from the microphone (112) in real-time on an administrator interface module (102b).

[0064] At step 270, the examination module (102) enables the students to access the questions within the first electronic device (110) and allows students to submit a digital answer online through a student interface module (102a), by capturing images of a physical answer sheet with a back camera (116) of the first electronic device (110). The student gets the questions on the student interface module (102a) and writes answers on the physical answer sheet. After writing the answers the student captures photos of the physical answer sheet with the back camera (116) of the first electronic device (110) and uploads the digital answers on the examination module (102). Also, the student submits the physical answer sheets to the proctor.

[0065] At step 270, the examination module (102) enables an evaluator to evaluate the digital answer sheet submitted by the student through the administrator interface module (102b) of a second electronic device (120), the student interface module (102a) and the administrator interface module (102b) are connected to an interface module (132) of the server (130). The uploaded digital answers are stored in the server's central database (134). The evaluator retrieves the digital answer sheet from the server (130) and the physical answer sheet from the student and compares both to detect any discrepancies or data tempering if required.

[0066] At step 280, the evaluator compares the digital answers from the central database (134) and the physical answer sheet submitted by the student simultaneously along with the images, screenshots, and audio recordings to evaluate and identify cheating or discrepancies or data tempering if required. The examination module (102) captures the examination data from the first electronic device (110), including real-time screenshots, images of the student, and audio recordings, and stores them in the central database (134). During the examination, when the student writes each answer and makes the digital answer by capturing the photos of the physical answer sheet, the digital answers are stored in the central database (134), and at the same time, the virtual camera (114) captures the screenshots of the first electric device and stores the captured screenshot in the central database (134). The front camera (114) also captures the student during the examination while the student uploads the digital answer sheet. Further, the microphone (112) is continuously recording the audio of the student during the examination. All three data from the student interface module (102a) of the first electronic device (110), including images of the front camera (114), the screen shorts of the virtual camera (118), and the audio recording are stored in the central database (134).

[0067] The examination module (102) monitors the receiving examination data from the first electronic device (110) and detects any violations within the captured images of the student, such as blurry images, no face, multiple faces, and the like. The examination module (102) detects any violations within the recorded audio of the student during the examination such, as multiple voices, voices when the student's mouth not moving, whispering, and like.

[0068] The examination module (102) generates and organizes collage and video files daily using examination data from individual students. The examination module (102) retrieves data from the central database (134), combines all the data individually, and makes college and video files of each student. The examination module (102) enables the evaluator to retrieve and analyse evidence such as the digital answer sheet, collages, and video files from the first electronic device (110). Upon detecting the violation, the evaluator can disqualify the student.

[0069] The method (200) ends at step 260.

[0070] For example, the process for onscreen evaluation begins with the proctor creating a question bank in the examination module (102) and storing it in the central database (134). The question bank includes a variety of questions categorized by subject, marks, and weightage. Based on proctor commands, the examination module generates a questions by importing questions from the central database (134). These questions can include multiple formats, such as multiple-choice, true/false, fill-in-the-blanks, and essay-style questions.

[0071] Before the student accesses the questions, the examination module verifies the functionality of the front camera (114) and microphone (112) on the first electronic device (110). If any issues are found, the examination module (102) denies access to ensure proper monitoring. Once the questions are accessed, the examination module (102) activates a restricted browsing mode, blocking online searches or unauthorized applications during the exam.

[0072] During the exam, live proctoring is enabled using the front camera (114), virtual camera (118), and microphone (112). The examination module (102) continuously captures images, screenshots, and audio, displaying them in real-time on the administrator interface module (102b) for monitoring. Students write answers on physical answer sheets and use the back camera (116) to capture and upload these as digital answers. The uploaded answers are stored in the central database (134) for evaluation.

[0073] The evaluator may retrieve both the digital answers and physical answer sheets for comparison and analyses the captured images, screenshots, and audio for potential discrepancies or data tempering. The examination module (102) detects irregularities such as blurry images, multiple faces, or suspicious sounds. Collages and video summaries are generated for detailed evidence. If violations are confirmed, appropriate actions, including disqualification, may be taken.
