Gritton, D G

This invention is comprised of a method and apparatus for the secure transmission of static data from a tag to a remote reader. Each time the static data is to be transmitted to the reader, the 10 bits of static data are combined with 54 bits of binary data, which constantly change from one transmission to the next, into a 64-bit number. This number is then encrypted and transmitted to the remote reader where it is decrypted to produce the same 64 bit number that was encrypted in the tag. With a continual change in the value of the 64 bit number in the tag, the encrypted numbers transmitted to the reader will appear to be dynamic in character rather than being static.
