A method to authenticate a server to a client is provided, including in-band and out-of-band techniques. At least a first shared secret identifies a server path, including a plurality of pre-defined locations on a frame of reference (e.g. a grid). An authentication session is initiated upon receiving a client identifier at the server-side resources. A current session instance of the grid is presented to the client, populated with characters. The process includes sharing between the client and the server a challenge identifying a random subset of the plurality of predefined locations in the server path, and a response including characters that match the characters in the locations on the server path identified by the challenge. As a result, client is capable of verifying that the server has access to the first shared secret. Then a protocol is executed to authenticate the client to the server.

A graphical user interface supports an interactive client-server authentication based on Random Partial Pattern Recognition algorithm (RPPR).

A graphical user interface presents a clue generated at the server to the client, such positions in the ordered set of a random subset of data fields from the ordered set. The client enters input data in multiple fields of the interface according to the clue, and the server accepts the input data from the client. The input data includes storage units representing alpha-numeric characters, images and colors corresponding to the field contents for the data fields. The interface includes indicators for elapsed time and status of the authentication session.

An interactive client-server authentication system and method are based on Random Partial Pattern Recognition algorithm (RPPR). In RPPR, an ordered set of data fields is stored for a client to be authenticated in secure memory. An authentication server presents a clue to the client via a communication medium, such positions in the ordered set of a random subset of data fields from the ordered set. The client enters input data in multiple fields according to the clue, and the server accepts the input data from the client via a data communication medium. The input data corresponds to the field contents for the data fields at the identified positions of the random subset of data fields. The server then determines whether the input data matches the field contents of corresponding data fields in a random subset.
