Abstract

Described is a method and system for authenticating identity of a person using a portable device. The portable device may includes an imager, an image processing unit and a processor. The image processing unit reads encoded data in a first image from an imager of the device. The image processing unit extracts a portion of a second image from the imager to generate extracted portion data. The extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated. Stored biometric data for a person is located based on the data read from the first image. The processor compares the extracted portion data of the second image to the stored biometric data for a person.

Claims

1. A portable device for authenticating identity of a person, comprising:

an imager;

an image processing unit reading encoded data in a first image from the imager, the image processing unit extracting a portion of a second image from the imager to generate extracted portion data, wherein the extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated; and

a processor for comparing the extracted portion data of the second image to stored biometric data for the person, wherein the stored biometric data is located based on the data read from the first image.

2. The portable device according to claim 1, wherein the extracted portion data of the second image includes at least one of a facial recognition data and an image data of the person.

3. The portable device according to claim 1, wherein the extracted portion data includes an iris of the person.

4. The portable device according to claim 1, wherein the first image is a bar code having an identifier of the person, the stored biometric data being stored a remote server, the stored data being located based on the identifier.

5. The portable device according to claim 1, wherein the first image is a two-dimensional bar code storing the stored biometric data.

6. The portable device according to claim 5, wherein the two-dimensional bar code is secured using at least one an encryption system and a public/private key structure system.

7. The portable device according to claim 1, wherein the imager is a dual focus imager.

8. The portable device according to claim 1, wherein the imager is dual-illumination image using a visual spectrum and a non-visible spectrum.

9. The portable device according to claim 2, wherein the imager utilizes a visible spectrum to obtain the first and second images, the image processing unit generating at least one of the facial recognition data and the image data using the extracted portion of the second image.

10. The portable device according to claim 3, wherein the imager utilizes a non-visible spectrum to obtain the second image, the image processing unit generating the iris data as a function of the extracted portion of the second image.

11. A method for authenticating identity of a person using a portable device, comprising the step of:

reading encoded data in a first image from an imager of the device using an image processing unit of the device;

extracting a portion of a second image from the imager using the image processing unit to generate extracted portion data, wherein the extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated;

locating stored biometric data for a person based on the data read from the first image; and

comparing the extracted portion data of the second image to the stored biometric data for a person using a processor of the device.

12. The method according to claim 11, wherein the extracted portion data includes iris data of the person.

13. The method according to claim 11, wherein the first image is a bar code having an identifier of the person and the stored biometric data is stored in a remote server, the method further comprising the steps of:

extracting the identifier from the bar code; and

locating the stored biometric data based on the identifier.

14. The method according to claim 11, wherein the first image is a two-dimensional bar code storing the stored biometric data.

15. The method according to claim 14, wherein the two-dimensional bar code is secured using at least one an encryption system and a public/private key structure system.

16. The method according to claim 12, further comprising the steps of:

obtaining the second image using the imager which utilizes a non-visible spectrum;

with the image processing unit, generating the iris data as a function of the extracted portion of the second image; and

comparing the iris data to the stored biometric data.

17. A system for authenticating identity of a person, comprising:

a first image; and

a portable device including an imager, an image processing unit and a processor, the image processing unit reading encoded data in the first image from the imager, the image processing unit extracting a portion of a second image from the imager to generate entreated portion data,

wherein the extracted portion of the second image corresponds to a portion of a person whose identity is to be authenticated, the processor comparing the extracted portion of the second image to stored biometric data for a person, and wherein the stored biometric data is located based on the data read from the first image.

18. The system according to claim 17, wherein the extracted portion is an iris of the person, the imager utilizing a non-visible spectrum to obtain the iris, the image processing unit generating the iris data as a function of the iris, the processor comparing the iris data to the stored biometric data to determine if the person is authenticated.

19. The system according to claim 17, further comprising:

a remote server storing the stored biometric data, wherein the first image is a bar code having an identifier of the person, the stored data being located in the remote server based on the identifier.

20. The system according to claim 17, wherein the first image is a two-dimensional bar code storing the stored biometric data.

21. The system according to claim 20, wherein the two-dimensional bar code is secured using at least one an encryption system and a public/private key structure.

22. The system according to claim 17, wherein the imager is dual-illumination image using a visual spectrum and a non-visible spectrum.
