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.
