ABSTRACT:
A personal identity authentification system is provided in which parametric data of an authorized possessor is encrypted into a memory of a portable transceiver device. The portable transceiver device, carried by a possessor, may be activated by an identity request transmitted from a nearby, authorized verification device. Upon activation, the portable transceiver transmits the encrypted data to the verification device which, when decoded by a verification unit, provides positive identification of the authorized possessor.
