Abstract

A system and method for authenticating the identity of a subject from a plurality of subjects. The system utilises a scanner and processor for mapping locations of blood vessels and running a comparison between images to identify the subject based on the type and location of the subject'"'"'s blood vessels.

Claims

1. A system for biometrically authenticating the identity of a subject from a plurality of subjects, said system comprising:

at least one scanner, said scanner for capturing information relating to a first blood vessel type and a second blood vessel type within regions of interest on each subject; and

at least one processor coupled to said scanner wherein at least one processor is adapted to;

map the locations of the first and second blood vessel types within the region of interest to produce a template image of the region of interest for each subject wherein each template image includes information on the locations of the first and second blood vessel types for the subject; and

wherein at least one processor is further configured to;

receive from at least one scanner sample data obtained from a region of interest on a subject;

locate the positions of a first blood vessel type and a second blood vessel type within the region of interest;

generate a sample image of the region of interest including the positions of the first blood vessel type and the second blood vessel type within the region of interest; and

compare the positions of the first blood vessel type and the second blood vessel type of the sample image with the positions of the first vessel type and the second blood vessel type of each template image to verify the identity of the subject.

2. The system of claim 1, wherein the scanner includes:

at least one infrared source for directing infrared radiation toward the region of interest;

at least one infrared sensor for receiving infrared radiation reflected from said region of interest;

at least one ultrasonic transducer for directing ultrasonic energy toward the region of interest;

and at least one acoustic sensor for receiving ultrasonic energy reflected from said region of interest;

wherein the at least one processor is adapted to;

determine the locations of blood vessels of a first vessel type within the region of interest based on the reflected infrared radiation; and

determine the locations of blood vessels of a second blood vessel type within the region of interest based on the reflected ultrasonic energy.

3. The system of claim 2, wherein the ultrasonic energy is pulsed.

4. The system of claim 2, wherein the ultrasonic energy is emitted as a plurality of beams directed at differing angles to the region of interest.

5. The system of claim 2, wherein the positions of the first blood vessel type are determined by identifying one or more regions within the region of interest having the highest rate of absorption of the incident infrared radiation.

6. The system of claim 2, wherein the positions of the second blood vessel type are determined by identifying the direction and/or the rate of fluid flow through the blood vessels within the region of interest.

7. The system of claim 6, wherein directionality of the fluid flow through the blood vessels is determined utilizing Doppler shift detection.

8. The system of claim 6, wherein the rate of fluid flow through the blood vessels is determined utilizing range gating to determine fluid velocity relative to each blood vessel'"'"'s cross sectional area.

9. The system of claim 1, wherein the first blood vessel type is venous and the second blood vessel type is arterial.

10. The system of claim 1, wherein the processor is coupled to a security system having one or more auxiliary devices for controlling movement of subjects between locations within the security system and wherein the processor is further configured to verify that a subject has permission to enter a location.

11. The system of claim 10, wherein the processor is configured to actuate the one or more auxiliary devices to grant the subject access to the location on determining that they have permission to enter the location and on verification of the subject identity.

12. The system of claim 1, wherein the system is integrated into a point of sale system, further comprising a plurality of said scanners and said processors, each of said scanners being positioned at various retail establishments within the point of sale system;

each of said processors being configured to communicate with each retailer'"'"'s payment gateway to verify the identity of a subject prior to commencement of a transaction between the payment gateway and the subject'"'"'s financial institution.

13. The system of claim 1, wherein each subject is provided with a unique identification number and wherein the processor is configured to request the input of the identification number to verify the subject'"'"'s identity.

14. The system of claim 1, wherein the processor is configured to send a message to the subject on access to the system, the subject being required to respond to the message before further processing of the subject commences.

15. The system of claim 1, wherein the system directs the subject to undertake a secondary identification procedure on failure to determine the subject'"'"'s identity.

16. A method for authenticating the identity of a subject from a plurality of subjects, said method including the steps of:

receiving from a scanner information relating to the locations of blood vessels of a first blood vessel type within an area of interest of the subject;

receiving from a scanner information relating to the locations of blood vessels of a second blood vessel type within the area of interest of the subject;

generating a template image of the area of interest for each subject wherein each template image includes information on the locations of the first and second blood vessel types for the subject;

receiving from the scanner sample data relating to the first and second blood vessel types within the area of interest on a subject;

locating positions of the first and second blood vessel types within the area of interest;

generating a sample image of the area of interest including the positions of the first blood vessel type and the second blood vessel type within the area of interest; and

comparing the positions of the first blood vessel type and the second blood vessel type of the sample image with the positions of the first vessel type and the second vessel type of each template image to verify the identity of the subject.
