Inventorship Yahya Zia, Severn, MD (US)

Claim of US Patent No. 10,169,565

1. A method of dynamically adapting a secure graphical password sequence by executing computer-executable instructions stored on a non-transitory computer-readable medium comprising:providing a computing device;
the computing device performing:
authenticating a user to request access to a restricted user account on the computing device;
defining a plurality of element selection requirements for a password sequence;
defining a plurality of preferences for the password sequence and a selection grid, the selection grid being used to input the password sequence;
dynamically generating the selection grid from the element selection requirements and the plurality of preferences, the selection grid comprising a plurality of grid cells containing at least one graphical element from a plurality of graphical elements, each of the graphical elements being associated with at least one element category and an authentication value;
displaying a user interface with the selection grid;
receiving a plurality of cell selections as the password sequence, each of the cell selections corresponding to one of the grid cells and corresponding to one of a plurality of sequential locations in the password sequence;
comparing the password sequence to the element selection requirements in order to authenticate the password sequence as a valid password sequence;
rejecting the password sequence as a current invalid password sequence;
accepting the password sequence as a current valid password sequence in response to determining the password sequence as valid; and
providing the access to the restricted user account in response to authenticating the user requesting the access with the current valid password sequence;
allowing the user to update parameters of the password sequence via successful or unsuccessful logins over time;
adding at least one additional layer of complexity to the element selection requirements in response to finding the pattern similarities between the current and previous invalid password sequences; and
randomizing or increasing or decreasing a probability of displaying incorrect selections.
