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.

Claims

1. An identity authentification system comprising:

A) at least one identification transceiver having;

1) means for receiving transmitted identify requests from a verification transceiver;

2) memory means for storing encrypted parametric data for an authorized possessor; and

3) means for transmitting the encrypted parametric data to the verification transceiver in response to the request received by the means for receiving identity requests, and

B) at least one verification transceiver having;

1) means for periodically transmitting identity requests;

2) means for receiving the transmitted encrypted parametric data for the authorized possessor from the means for transmitting within the identification transceiver;

3) means for decrypting the received parametric data;

4) means for measuring parameters of an identification transceiver possessor; and

,

5) means for comparing the decrypted parametric data with the measured parametric data of a possessor and, upon occasion where the possessor is the authorized possessor, granting access to the authorized possessor.

2. The system as in claim 1 wherein the parametric data includes biometric data.

3. The system as in claim 1 wherein the means for comparing comprises a CRT display and an operator performing duplicate parametric measurements.

4. The system as in claim 1 wherein the means for comparing comprises a computer with a connected parametric measuring system.

5. The system as in claim 1 wherein the encrypted parametric data includes encoded visual data of the authorized possessor.

6. The system as in claim 1 wherein the encrypted parametric data includes indicia of identity.

7. The system as in claim 6 wherein the verification transceiver further includes means for transmitting a verification transceiver ID number with the identity request and the identification transceiver further includes means for responding with selected encoded indicia of identity depending on number of the verification transceiver.

8. A method of providing positive identification of a possessor of an identification transceiver by comparing parameters stored in the identification transceiver with physical parameters of the possessor and and wherein possessors of identification transceivers may be authorized and, upon occasion, unauthorized and wherein certain physical parameters of the authorized possessor have been stored in an encrypted manner in the identification transceiver for retrieval by a verification transceiver for purposes of identifying the possessor as being an authorized possessor, such method comprising the steps of:

A) transmitting an identity request by the verification transceiver to the identification transceiver;

B) receiving the identity request by the identification transceiver;

C) transmitting an identity response to the verification transceiver containing at least some of the stored encrypted parameters;

D) measuring parameters of an identification transceiver possessor;

E) decrypting and comparing at least some of the decrypted parameters with the measured parameters of an identification transceiver possessor to identify an authorized possessor; and

F) granting access to an authorized possessor based upon matching decrypted and measured parametric data.

9. The method as in claim 8 wherein the parametric data contains biometric data.

10. The method as in claim 8 wherein the encrypted parametric data includes encoded visual data of the authorized possessor.

11. The method as in claim 8 wherein the encrypted parametric data includes indicia of identity.

12. The method as in claim 11 wherein the verification transceiver transmits a verification transceiver ID number with the identity request and the identification transceiver responds with selected encoded indicia of identity depending on the ID of the verification transceiver.

13. An identification transceiver comprising:

A) means for receiving transmitted identity requests from a verification transceiver;

B) memory means for storing encrypted parametric data for an authorized possessor; and

, C) means for transmitting the encrypted parametric data to the verification transceiver in response to the request received by the means for receiving identity requests.

14. The transceiver as in claim 13 wherein the parametric data includes biometric data.

15. The transceiver as in claim 13 wherein the encrypted parametric data includes encoded visual data of the authorized possessor.

16. The transceiver as in claim 13 wherein the encrypted parametric data includes indicia of identity.

17. The transceiver as in claim 16 wherein the verification transceiver transmits a verification transceiver ID number with the identity request and the identification transceiver contains a means for transmitting selected encoded indicia of identity depending on the ID number of the verification transceiver.

18. An identity authentification system comprising:

A) at least one identification transceiver having;

1) means for receiving transmitted identity requests from a verification transceiver;

2) means for measuring parametric data of a possessor;

3) means for encrypting the measured parametric parameter of the possessor using a non-symmetric Public Key algorithm and an encode key; and

4) means for transmitting the encrypted parametric data to the verification transceiver in response to the request received by the means for receiving identity requests, and

B) at least one verification transceiver having;

1) means for periodically transmitting identity requests;

2) memory means for storing a measured parameter of an authorized user;

3) means for receiving the transmitted encrypted parametric data for the possessor from the means for transmitting within the identification transceiver;

4) means for decrypting the received parametric data using the non-symmetric Public Key algorithm and a decode key;

5) means for comparing the decrypted measured parametric data of the possessor with the stored parametric data of the authorized user; and

6) means for, upon occasion where the possessor is the authorized user, providing access to the authorized user.

19. The system as in claim 18 providing communication access to a portable radio or telephone.

20. The system as in claim 18 wherein the parametric data includes biometric data.
