Assignee:

Metavante Corporation - Brown Deer WI

International Classification:

G06F 21/00

Abstract:

Methods and systems are provided for generating a party static token to be used in combination with a party dynamic token for identifying a party to a host system. Identification information that identifies the party to the host system is received. Such identification information includes a host dynamic token and a host static token. A false host dynamic token that differs from the host dynamic token is generated. The host dynamic token and the false host dynamic token are encrypted. In addition, information that uniquely identifies the party dynamic token is encrypted. The party static token is produced from a combination of the encrypted host dynamic token, the encrypted false host dynamic token, and the encrypted information that uniquely identifies the party dynamic token.

Abstract:

According to the invention, a system for verifying a steganogram is disclosed. Included in the system are a first system, a second system, a steganogram, and a steganogram preparer. The first system is coupled to an access device by way of a public network. The second system coupled to the first system. The steganogram is comprised of random data and encrypted information, which is randomly dispersed throughout the steganogram. The steganogram preparer provides the steganogram to the access device. The first system gathers a subset of the encrypted information from the access device. The second system receives the subset or a derivative of the subset and verifies that the subset or a derivative of the subset is from the steganogram.
