AUTHENTICATING A USER WITH A PASSCODE USING A PASSCODE ENTRY TABLE

摘要

Authenticating a user with a passcode using a passcode entry table includes a sequence of characters and a location within a grid associated with each character, wherein entry of the passcode is performed using a displayed passcode entry table comprising a number of selectable cells, where selection of a cell enters a character of a passcode being entered, each cell including a number of different characters in different grid locations displaced within the cell, such that the entry of one particular character in the passcode is made by selecting a cell. The method includes receiving an entered passcode, the entered passcode comprising a series of selected cells, and verifying that each sequentially selected cell matches a corresponding character of the passcode, as to both the corresponding character of the passcode and that character displayed at a corresponding grid location within the selected cell.

主权项

1. A computer implemented method for authenticating a user with a passcode, the passcode comprising a sequence of characters and a location within a grid associated with each character, wherein entry of the passcode is performed using a displayed passcode entry table comprising a number of selectable cells, where selection of a cell enters a character of a passcode being entered, each cell including a number of different characters in different grid locations displaced within the cell, such that the entry of one particular character in the passcode is made by selecting a cell, the corresponding display of which includes the particular character of the passcode displayed at the correct corresponding grid location within the cell, the method comprising:
receiving an entered passcode, the entered passcode comprising a series of selected cells, each cell representing a plurality of different characters arranged at different grid locations within the cell; and, verifying that each sequentially selected cell matches a corresponding character of the passcode, as to both the corresponding character of the passcode and that character displayed at a corresponding grid location within the selected cell, wherein, when the sequentially selected cell does not match the corresponding character of the passcode as to both the character and the grid location corresponding to the character, the entry of the passcode is not authenticated.
