Method for enabling authentication or identification, and related verification system

1. A method enabling the authentication or identification of a person, using a first electronic device comprising an image-capturing unit and a data transmission unit, said method including a phase of registering said person with a verification system, said registration phase comprising the following steps:

capturing, using an image-capturing unit of said first electronic device, a first image of at least one object of any kind that is secretly selected by the person among any object or part of an object to be photographed and that the person always has on his or her person, said object being not determined in advance;

transmitting said first image to the verification system in a secure manner by means of the data transmission unit of said first electronic device;

further including an authentication or identification phase relative to said person, using a second electronic device, the authentication or identification phase comprising the following steps carried out in the verification system:

receiving from the second electronic device a second image of at least one object that is identical or similar to the object in the first image;

comparing the second image to at least the first image; and

deciding that the person is authenticated or identified successfully when the comparison of the second image to the first image reveals a match between their respective objects;

wherein the second image has been freshly captured using an image-capturing unit of said second electronic device, for the purposes of the authentication or identification of the person in said verification system and is not identical the first image.

2. The method according to claim 1 , wherein at least a first personal data item for said person is sent to the verification system as a supplement to the first image.

3. The method according to claim 1 , wherein the first electronic device and the second electronic device are the same device.

4. The method according to claim 1 , wherein the first electronic device and/or the second electronic device belong to said person.

5. The method according to claim 1 , wherein the second image is sent in a secure manner from the second electronic device to the verification system.

6. The method according to claim 1 , further including:

wherein at least a first personal data item for said person is sent to the verification system as a supplement to the first image;

and further comprising the steps of:

receiving, from the second electronic device, a second personal data item for said person corresponding to the first personal data item, and

comparing the second personal data item to at least the first personal data item, and

deciding that the person is authenticated or identified successfully when the comparison of the second image to the first image reveals a match between their respective objects and the comparison of the second personal data item to the first personal data item reveals a match between the second personal data item and the first personal data item.

7. A verification system enabling the authentication or identification of a person, said verification system comprising:

a first receiving unit for receiving in a secure manner, from a first electronic device, a first captured image of at least one object of any kind that is secretly selected by the person among any object or part of an object to be photographed and that the person always has on his or her person, said object being not determined in advance;

a second receiving unit for receiving in a secure manner, from a second electronic device, a second image of at least one object that is identical or similar to the object of the first image;

an image comparison unit that compares the second image to at least the first image;

a decision unit which decides that the person is authenticated or identified successfully when the comparison of the second image to the first image performed by the image comparison unit reveals a match between their respective objects;

wherein the second image has been freshly captured using an image-capturing unit of said second electronic device, for the purposes of the authentication or identification of the person in said verification system and is not identical to the first image.

8. The verification system according to claim 7 , said verification system being distributed across multiple entities.

9. A non-transitory computer readable storage medium, with a program stored thereon, said computer program comprising code instructions for implementing the method according to claim 5 when it is loaded onto and executed by computer means.
