Abstract (en)
[origin: GB2291522A] A dual-secure authentication technique takes advantage of the inherently secure nature of certain data storage media, such as that based upon the structural variation, from place to place over a strip, of magnetic characteristic, to attach to a valued article a secure identity code. The security is further enhanced by incorporating that code, together with further data, "signing" the code and further data using the secret key of a crytosystem pair and attaching the signed information to the article. Authentication requires the signed information to be de-crypted using the public key of the cryptosystem pair and ensuring that the code so recovered tallies with that recorded in the secure medium. <IMAGE>
