Abstract

The innovation discloses systems and methods of authenticating users using vein or blood vessel characteristics. The innovation retrieves, based on an authentication request, an authentication image associated with a user. The authentication image comprises a first predetermined point and a second predetermined point. The innovation projects the authentication image onto a body part of the user and reads a blood vessel from the body part. The user orients the blood vessel such that it corresponds to the predetermined points in the projected authentication image. The user is authenticated when the blood vessel appears to connect the predetermined points in the direction of the blood flow.

Claims

1. A method, comprising:

retrieving, based on an authentication request, an authentication image associated with a user, wherein the authentication image is a non-blood vessel image that comprises a first predetermined point and a second predetermined point within the authentication image;

projecting the authentication image onto a body part of the user, the body part of the user comprises a blood vessel;

reading blood vessel data from the body part of the user on which the authentication image is projected;

comparing the blood vessel data with the first predetermined point and the second predetermined point;

receiving an indication that the blood vessel is aligned with the authentication image such that the blood vessel appears to connect the first predetermined point and the second predetermined point within the authentication image projected onto the body part of the user;

determining the blood vessel data connects the first predetermined point and the second predetermined point based on the comparison; and

authenticating the user based on the determination.

2. The method of claim 1, wherein the authentication image is a predetermined stock image and associated with previously recorded blood vessel data.

3. The method of claim 1, comprising:

providing a set of images to the user, the set of images includes the authentication image and at least one other image; and

receiving a selection of the authentication image.

4. The method of claim 1, wherein the body part of the user is an area of the user selected during a registration.

5. The method of claim 4, wherein the authenticating comprises:

confirming the body part of the user matches the user selected body part of the user.

6. The method of claim 1, wherein the blood vessel data includes a blood vessel position, a blood flow direction, a pulse, a vital sign, or combinations thereof.

7. The method of claim 6, wherein the authenticating comprises:

determining the blood flow direction is from the first predetermined point to the second predetermined point.

8. The method of claim 1, wherein the first predetermined point and the second predetermined point are selected during a registration.

9. The method of claim 8, further comprising:

determining a plurality of intermediary points in the authentication image based on a registration blood vessel image connecting the first predetermined point and the second predetermined point; and

wherein the authenticating comprises determining the blood vessel connects the first predetermined point, the second predetermined point, and at least a subset of the plurality of intermediary points.

10. A system, comprising:

an image database that comprises a set of images that include an authentication image associated with a user, wherein the authentication image is a non-blood vessel image;

a projection component that renders the authentication image onto a body part of the user, the body part of the user containing a blood vessel;

a biometric scanner that reads blood vessel data from the blood vessel on which the authentication image is overlaid; and

an authentication component that;

compares the blood vessel data with a first predetermined point and a second predetermined point within the authentication image;

determines the blood vessel data connects the first predetermined point and the second predetermined point within the authentication image when projected on the body part; and

verifies an identity of the user based on the blood vessel data in relation to the authentication image overlaid onto the body part of the user.

11. The system of claim 10, further comprising:

a tracking component that monitors alignment of the blood vessel with the projected authentication image such that the blood vessel appears to connect the first predetermined point and the second predetermined point.

12. The system of claim 10, further comprising:

a registration component that provides previously recorded authentication data associated with the user.

13. The system of claim 12, wherein the authentication data includes at least one of:

a user selection of the body part of the user, a user selection of the authentication image, a user selection of the first predetermined point and the second predetermined point, and blood vessel data comprises a blood vessel position, a blood flow direction, a pulse, or other vital signs.

14. The system of claim 13, comprising:

wherein the registration component is configured to determine a plurality of intermediary points in the authentication image based on the blood vessel position data connecting the first predetermined point and the second predetermined point; and

wherein the authentication component determines the blood vessel connects the first predetermined point, the second predetermined point, and the plurality of intermediary points.

15. The system of claim 10, further comprising:

a graphical user interface that;

outputs a set of non-blood vessel images to the user; and

designates an image of the set of non-blood vessel images as the authentication image based on a selection from the set of non-blood vessel images.

16. A non-transitory computer readable medium having instructions to control one or more processors configured to:

register a user, the registration includes capturing user blood vessel data, a user selection of an authentication image having a first predetermined point and a second predetermined point, wherein the authentication image is a non-blood vessel image, and a user selection of a body part;

receive an authentication request;

render an authentication image onto a body part of the user, the body part of the user including a blood vessel;

read blood vessel data from the blood vessel on which the authentication image is rendered;

compare the blood vessel data with the first predetermined point and the second predetermined point within the authentication image;

determine the blood vessel data connects the first predetermined point to the second predetermined point within the authentication image when rendered on the body part; and

authenticate the user based on the connection determination.

17. The non-transitory computer readable medium of claim 16, wherein the one or more processors are further configured to:

determine a plurality of intermediary points in the authentication image based on blood vessel position data connecting the first predetermined point and the second predetermined point; and

determine the blood vessel connects the first predetermined point, the second predetermined point, and the plurality of intermediary points.
