Abstract

Systems and method for comparing images are disclosed. In particular, certain disclosed embodiments relate to determining whether a user of a mobile device corresponds to a previously authenticated user, the user having been previously authenticated via an identity document. The determination may be made by accessing an integrated circuit component of the identity document, capturing a first image corresponding to a portion of the identity document containing a photographic image of the previously authenticated user, and capturing a second image corresponding to a user of the mobile device.

Claims

1. A method of determining whether a user of a mobile device corresponds to a previously authenticated user, the previously authenticated user having been previously authenticated using an identity document, the method comprising:

accessing, by a chip reader associated with the mobile device, an integrated circuit component of an identity document;

retrieving digital image data indicative of a digital image of the previously authenticated user;

capturing, using a camera associated with the mobile device, a first image comprising first image data, wherein the first image corresponds to an image of a portion of the identity document containing a photographic image visible on the identity document;

capturing, using the camera associated with the mobile device, a second image comprising second image data, wherein the second image corresponds to the user of the mobile device;

comparing the retrieved digital image data to the first image data and the second image data;

determining, based on the comparing of the retrieved digital image data to the first image data and the second image data, whether the first image, the second image, and the digital image represent the same user; and

forming an association between the previously authenticated user, and the mobile device when it is determined that the first image, the second image, and the digital image represent the same user.

2. The method of claim 1, further comprising:

comparing the retrieved digital image data to the first image data; and

verifying, based on the comparing of the retrieved image data to the first image data, the validity of the identity document.

3. The method of claim 2, wherein the identity document comprises first identity data, and wherein verifying the validity of the identity document is based on the first identity data, and wherein the method further comprises:

deriving the first identity data from the identity document.

4. The method of claim 3, wherein at least some of the first identity data is stored in the integrated circuit component, and wherein deriving the first identity data from the identity document comprises accessing, by a chip reader associated with the mobile device, the integrated circuit component to retrieve the first identity data.

5. The method of claim 3, wherein at least some of the first identity data is visible on said identity document, and wherein the first image comprises a portion of the identity document containing the first identity data, and wherein the deriving the first identity data comprises:

analyzing, by the mobile device, features within the first image; and

deriving the first identity data from the identity document based on the analysis performed by the mobile device.

6. The method of claim 1, wherein the identity document further comprises second identity data relating to the previously authenticated user, and wherein the method further comprises:

deriving the second identity data from the identity document; and

storing the derived second identity data and an identifier for the previously authenticated user.

7. The method of claim 6, wherein at least some of the second identity data is stored in the integrated circuit component, and wherein deriving the second identity data comprises:

accessing, by a chip reader associated with the mobile device, the integrated circuit component; and

retrieving the second identity data from the integrated circuit component.

8. The method of claim 6, wherein at least some of the second identity data is visible on the identity document, and wherein the first image comprises a portion of the identity document containing the second identity data, and wherein said the method further comprises extracting the second identity data from the first image using Optical Character Recognition.

9. The method of claim 1, wherein comparing the retrieved digital image data to the first image data and the second image data comprises sending the retrieved digital image data and the first image data and the second image data to a remote processing system for carrying out the comparison.

10. The method of claim 1, wherein comparing the retrieved digital image data to the first image data and the second image data comprises performing the comparison by the mobile device.

11. A system for determining whether a user of a mobile device corresponds to a previously authenticated user, the previously authenticated user having been previously authenticated using an identity document, the system comprising:

a processor;

a memory in data communication with the processor;

a chip reader associated with the mobile device configured to;

access an integrated circuit component of the identity document; and

retrieve digital image data indicative of a digital image of the previously authenticated user;

a camera associated with the mobile device configured to;

capture a first image comprising first image data, wherein the first image corresponds to an image of a portion of the identity document containing a photographic image visible on the identity document;

capture a second image comprising second image data, wherein the second image corresponds to the user of the mobile device; and

computer instructions stored in the memory, which, when executed by the processor, are configured to cause the system to;

compare the retrieved digital image data to the first image data and the second image data;

determine, based on the comparison, whether the first image, the second image, and the digital image represent the same user; and

,

form an association between the previously authenticated user when it is determined that the first image, the second image, and the digital image represent the same user.

12. The system of claim 11, wherein the computer instructions are further configured to cause the system to:

compare the retrieved digital image data to the first image data; and
