Abstract

The present invention comprises an apparatus and method for generating and storing an electronic portrait of a buyer within a personal device such as a mobile telephone. An electronic portrait enables the generation of a physical identifier for comparison to the buyer by a seller during a transaction. Using the physical identifier transmitted to the seller via a wireless communications link, the seller can establish whether or not the buyer is authorized to make the transaction.

Claims

1. A method for enabling identification of a buyer to be used in conjunction with a face to face sales transaction, comprising the steps of:

receiving, by a personal device of a buyer, from equipment of a seller, a public key that enables the personal device to encrypt information sent between the personal device of a buyer and the equipment of a seller;

generating an electronic portrait of a buyer, the electronic portrait enabling generation of a physical identifier for comparison to the buyer by a seller during the sales transaction;

storing the electronic portrait within a digital certificate in a personal device to enable access of the electronic portrait by the seller during the sales transaction wherein the personal device includes a service module stored within a memory of the personal device issued by an issuer that guarantees payment, the service module including at least one private key and the digital certificate, wherein the private key is an encryption tool which, when combined with the public key received from equipment of a seller enables the personal device to encrypt information transmitted between the personal device and the equipment of the seller via a wireless interface; and

transmitting the electronic portrait to the seller via the wireless interface during the sales transaction.

2. The method of claim 1, wherein the step of storing further comprises the step of storing the electronic portrait in an encrypted format within the personal device.

3. The method of claim 1, wherein the electronic portrait comprises at least one of:

an electronic photo of the buyer;

a graphic imprint of the buyer;

a mathematical imprint of the buyer;

a verbal description of the buyer;

an electronic audio imprint of the buyer; and

an electronic video imprint of the buyer.

4. The method of claim 1, wherein the personal device comprises at least one of a mobile telephone or an electronic personal device.

5. The method of claim 1, further including the step of placing the electronic device in a shielded area associated with the seller prior to transmitting the electronic portrait.

6. The method of claim 1, wherein the step of storing further comprises the steps of:

storing the electronic portrait at a remote location accessible via the personal device; and

storing an identifier within the personal device enabling access to the electronic portrait at the remote location.

7. The method of claim 1, wherein the wireless interface comprises a Bluetooth interface.

8. A method for enabling identification of a buyer to be used in conjunction with a sales transaction, comprising the steps of:

receiving, by a personal device of a buyer, from equipment of a seller, a public key that enables the personal device to encrypt information sent between the personal device of a buyer and the equipment of a seller;

receiving an electronic portrait contained within a digital certificate from the personal device via a short range wireless interface, the electronic portrait enabling generation of a physical identifier for comparison to the buyer by the seller using equipment of the seller wherein the personal device includes a service module stored within a memory of the personal device issued by an issuer that guarantees payment, the service module including at least one private key and the digital certificate, wherein the private key is an encryption tool which, when combined with the public key received from equipment of a seller enables the personal device to encrypt information transmitted between the personal device and the equipment of the seller via the wireless interface;

generating the physical identifier from the received electronic portrait;

displaying the physical identifier to the seller using equipment of the seller; and

completing the sales transaction if the physical identifier corresponds to the buyer.

9. The method of claim 8 further comprising the step of interconnecting with a personal device containing the electronic portrait via the Bluetooth interface.

10. The method of claim 8 further comprising the step of decrypting the electronic portrait.

11. The method of claim 8, wherein the electronic portrait comprises at least one of:

an electronic photo of the buyer;

a graphic imprint of the buyer;

a mathematical imprint of the buyer;

a verbal description of the buyer;

an electronic audio imprint of the buyer; and

an electronic video imprint of the buyer.

12. The method of claim 8, wherein the personal device comprises at least one of a mobile telephone or an electronic personal device.

13. The method of claim 8 further comprising the steps of comparing the physical identifier to the buyer.

14. The method of claim 8, wherein the step of receiving further comprises receiving from the personal device which is located in a shielded area.

15. The method of claim 8, wherein the step of receiving further includes the steps of:

receiving an identifier enabling access to a location remote from the personal device containing the electronic portrait; and

accessing the electronic portrait using the identifier.

16. The method of claim 8, wherein the short range wireless interface comprises a Bluetooth interface.

17. A method for enabling identification of a buyer to be used in conjunction with a sales transaction comprising the steps of:

receiving, by a personal device of a buyer, from equipment of a seller, a public key that enables the personal device to encrypt information sent between the personal device of a buyer and the equipment of a seller;

generating an electronic portrait of a buyer, the electronic portrait enabling generation of a physical identifier for comparison to the buyer by a seller;

storing the electronic portrait within a digital certificate in the personal device to enable access of the electronic portrait by the seller during the sales transaction wherein the personal device includes a service module stored within a memory of the personal device issued by an issuer that guarantees payment, the service module including at least one private key and the digital certificate, wherein the private key is an encryption tool which, when combined with the public key received from equipment of a seller enables the personal device to encrypt information transmitted between the personal device and the equipment of the seller via a wireless interface;

establishing a wireless communications link between a personal device and the seller;

receiving the electronic portrait from a buyer via the Bluetooth communications link;

generating the physical identifier from the received electronic portrait;

displaying the physical identifier to the seller on equipment of the seller; and

completing the sales transaction if the physical identifier corresponds to the buyer.

18. The method of claim 17, wherein the step of storing further comprises the step of storing the electronic portrait in an encrypted format within the personal device.

19. The method of claim 17 further comprising the step of decrypting the electronic portrait.

20. The method of claim 17, wherein the electronic portrait comprises at least one of:

an electronic photo of the buyer;

a graphic imprint of the buyer;

a mathematical imprint of the buyer;

a verbal description of the buyer;

an electronic audio imprint of the buyer; and

an electronic video imprint of the buyer.

21. The method of claim 17, wherein the personal device comprises at least one of a mobile telephone or an electronic personal device.

22. The method of claim 17, further comprising the step of comparing the physical identifier to the buyer.

23. The method of claim 17, further including the step of placing the electronic device in a shielded area associated with the seller prior to transmitting the electronic portrait.

24. The method of claim 17, wherein the step of storing further comprises the steps of:

storing the electronic portrait at a remote location accessible via the personal device; and
