[0086] FIG. 3A – 3Eillustrate an exemplary view of input unit after every execution by entity, in accordance with an embodiment of the present disclosure.
[0087] In an embodiment, FIG. 3A illustrates an input unit 104, where the input unit 104 can be a keypad with a predetermined matrix of six rows and six columns but not limited to the likes. In an illustrative embodiment, the input unit 104 can include a first set of block with one or more keys and a second set of blocks which are inactive. The number of blocks can be thirty-six in numbers according to the six rows and six columns matrix. In an illustrative embodiment, an entity can tap or enter one or more keys of the keypad in response with one or more functions, where the one or more functions can be configured with a display unit. In yet another illustrative embodiment, the one or more keys can include digits from zero to nine. The combination of the one or more keys tapped by the entity can pertain to Personal Identification Number (PIN).
[0088] In an illustrative embodiment, the input unit 104 can be operatively coupled with the processing unit, where the processing unit can be configured to shuffle the digits with random order by placing the second set of blocks which re inactive and can be considered as vacant spaces in the matrix. The matrix with thirty-six positions can be used to place digits from zero to nine with twenty-six vacant spaces. The one or more keys on the keypad can be configured to procure different positions according to the one or more keys tapped by the entity. In another illustrative embodiment, the processing unit can be configured to reshuffle the thirty-six positions after entry of each of the digit of the PIN, therefore chances of predicting the positions can be difficult. In yet another illustrative embodiment, the system 100 can facilitate in preventing from theft, fraud, and the likes associated with the PIN.
[0089] In an illustrative embodiment, the system 100 can include feature in which matrix can have six rows and six columns or of order six by six. The PIN can be of predetermined length and attributes and can have four numbers of digits, but not limited to the likes. The four-digit PIN makes the system secure and difficult to guess the PIN. In another illustrative embodiment, when the entity enters the PIN through the input unit like keypad, pattern for each of the one or more keys entered or tapped by the entity can be created. However, in this system, as the entity enters the one or more keys, the processing unit can be configured to reshuffle the keypad for each of the one or more keys entered or tapped by the entity. The reshuffling of the keypad makes difficult to predict the pattern created by entering of the one or more keys, where the combination of the one or more keys can include the PIN. The pattern becomes technically unpredictable due to randomness of the reshuffled keypad.
[0090] In an illustrative embodiment, the pattern can be created for each digit of the PIN entered by the entity and even if the PIN gets leaked, there can be zero chances of predict the pattern as different pattern can be created for same digit of the PIN.
[0091] In an embodiment, the FIG. 3B illustrates the input unit 104 with six rows and six columns matrix keypad. The keypad can include digits from zero to nine. In an illustrative embodiment, the entity can enter first key fromthe one or more keys, where the first key can be associated with the PIN. For example, the PIN can be 1234 and on entering 1, the processing unit can be configured to reshuffle the each of the one or more keys of the keypad. The position of the digits from zero to nine can be reshuffled.
[0092] In an embodiment, the FIG. 3C illustrates the input unit 104, and the entity enters second key of the PIN. On entering 2, the processing unit can be configured to reshuffle the each of the one or more keys of the keypad. The position of the digits from zero to nine can be reshuffled.
[0093] In an embodiment, the FIG. 3D illustrates the input unit 104, and the entity enters third key of the PIN. On entering 3, the processing unit can be configured to reshuffle the each of the one or more keys of the keypad. The position of the digits from zero to nine can be reshuffled.
[0094] In an embodiment, the FIG. 3E illustrates the input unit 104, and the entity enters fourth key of the PIN. On entering 4, the processing unit can be configured to reshuffle the each of the one or more keys of the keypad. The position of the digits from zero to nine can be reshuffled. In an illustrative embodiment, the processing unit can be configured to reshuffle the each of the one or more keys upon tapping each of the PIN key by the entity. After reshuffling of the each of the one or more keys of the keypad upon tapping each of the PIN key, the PIN can be matched with a preregistered codes stored in a database 210, where the matching can facilitate authentication of the PIN with the preregistered codes.
[0095] In an illustrative embodiment, the system 100 can be used for one or more mobile computing devices like cell phones keypad, and the likes, and also where password or PIN is required. In another illustrative embodiment, size of the matrix can depend on the length and characters of the PIN, and correspondingly a general formula for the size of the matrix can be size of the matrix=matrix [n+2] [n+2], where the first set of blocks for the matrix with one or more keys = = (n+2) *(n+2) and the second set of blocks which are inactive = (n+2) *(n+2) – (x). Here x can be range of input and n can be number of digits of the PIN. For example, for four-digit PIN 1234, the size of the matrix can be of six rows with six columns. Here n = 4, x = 10 and size of matrix = 36, number of one or more keys apart from inactive = 36, second set of blocks which are inactive= 26{0>= x <= 9}.
[0096] In an illustrative embodiment, size of the matrix can depend on the length and characters of the PIN, and accordingly the size of the matrix with number of first set of blocks and number of second set of blocks can be generalized.
