Abstract
A cryptographic device and corresponding method for producing a cloaked watermark which is a private watermark having the functionality of a public watermark. In one embodiment, the cryptographic device comprises an internal memory and a processor contained in a package. The internal memory provides a region for storage of key information used at least to produce the cloaked watermark. The processor is coupled to the internal memory and is responsible for producing a cloaked watermark based on the key and for inserting the cloaked watermark into an outgoing data set.
