Abstract
Methods, devices, and systems are presented that facilitate pattern-based user authentication. In a first embodiment, a user may request registration from an authentication server. The authentication server may provide at least one image to the user, wherein the image may comprise a matrix of cells. The user may choose a sequence of cells in the matrix as his or her secret, and may provide a userid and this secret to the authentication server. The authentication server may then validate and store the userid and/or secret. After this registration step, the user may request authentication from the authentication server. The authentication server may provide another image of a matrix of cells to the user. The user may then enter a sequence of symbols associated the sequence of cells that comprise his or her secret. The authentication server may compare the entered sequence of cells to the sequence of cells represented by the stored secret. If the two sequences match, then the user may be authenticated.
