Abstract
Access of a client device to a protected resource is controlled by issuing an authentication information request for a dynamic sub-set of client-side storage values previously stored on the client device by one or more servers. Authentication information is received from the client device based on the dynamic sub-set of client-side storage values. The client device is authenticated based upon verification of the received authentication information. The received authentication information from the client device is optionally encrypted. The client-side storage values comprise any value stored by one or more servers on the client device. The client-side storage values are substantially specific to the client device. The client-side storage values are optionally stored as a matrix. The requested dynamic sub-set of the client-side storage values may comprise one or more cells from a plurality of records in the matrix. The requested dynamic sub-set of the client-side storage values ensures that an authentication for two different login sessions do not request a same sub-set of the client-side storage values.
