Abstract

A secure 5-D user identification system using 3-D facial recognition plus micro-expression recognition and head gait analysis, and method for a body-worn sensor to increase security for users and thereby decrease security circumvention for illegitimate reproduction purposes.

Claims

1. A system for secure 5-DTM user identification, comprising:

a computing device comprising at least a processor, a memory, and a plurality of programming instructions stored in the memory and operating on the processor, wherein the programmable instructions, when operating on the processor, cause the processor to;

create a video recording of a user, wherein the user'"'"'s head is recorded from a range of positions and the recording comprises segments recorded using illumination in different wavelengths.

2. The system of claim 1, wherein the video recording is used to create a point cloud model of the user'"'"'s head.

3. The system of claim 1, wherein the video recording is used to create a 3-D mesh model of the user'"'"'s head.

4. The system of claim 1, wherein the head motion, including micro-movements, is tracked during at least a portion of the video recording and a signature is derived.

5. The system of claim 1, wherein the user'"'"'s hand motion is tracked, including micro-movements for those cases where a computing device is hand-held, using either the video motion vs. background or accelerometers built in to determine hand motion, with said hand motion being tracked over at least a portion of the video recording and a signature being derived.

6. The system of claim 1, wherein at least a portion of the video recording is recorded using near-infrared, and wherein the near-infrared portion of the recording is used to construct blood vessel maps in 3-D, and a graph of each section of the face including the eyes is derived, as well as the heart rate, blood oxygen, etc.

7. The system of claim 1, wherein all derived data, signatures, and other recordings are encrypted and stored securely.

8. The system of claim 7, wherein a current reading can be compared to a historical one, and an assessment of a match can be made to confirm or deny authenticity of identification.

9. The system of claim 8, wherein the authentication includes verification of non-tampering with the stored data.

10. The system of claim 1, wherein a body-worn sensor is used to monitor uninterrupted control of the device by the legitimate user.
