Abstract

Systems (110) and methods (200) securely authenticate an identity of an individual based on a pattern (350) that is traced by the individual. Embodiments of the present disclosure relate to prompting (210) an individual with a pattern (350) to trace when attempting to authenticate the identity of the individual during an identity authentication session. Motion-based behavior data that is generated by motions executed by the individual as the individual traces the pattern (350) is captured (230) via a motion-capturing sensor (130). The motion-based behavior data is unique to the individual and has a low likelihood of being duplicated by an unauthorized individual attempting to fraudulently pose as the individual. The captured motion-based behavior data is compared (250) to previously captured motion-based behavior data from previous traces (360) of the pattern (350) completed by the individual. The identity of the individual is authenticated (260) when the motion-based behavior data is within a threshold of the previously captured motion-based behavior data.

Claims

1. A method for securely authenticating an identity of an individual based on a pattern that is traced by the individual, comprising:

prompting the individual with a three-dimension authentication template that includes a defined three-dimension pattern for the individual to trace, the tracing of the defined pattern including a plurality of motions;

receiving the traced pattern from the individual generated from tracing wherein the plurality of motions generates input motion-based behavior data including behaviometric data associated with behaviometric characteristics of the individual;

obtaining previously captured motion-based behavior data associated with tracing of the defined three-dimension pattern by the individual as reference motion-based behavior data;

determining an inter-relationship of the input motion-based behavior data and an inter-relationship of the reference motion-based behavior data including generating a matrix for the input motion-based behavior data set and a matrix for the reference motion-based behavior data set, the matrices each reflecting the impact of pieces of data in the set on other pieces of data in the same set;

adjusting the input motion-based behavior data to account for the inter-relationship thereof using the matrices; and

comparing the adjusted input motion-based behavior data with the previously captured motion-based behavior data while maintaining the inter-relationship of both the input and reference motion-based behavior data to thereby authenticate the identity of the individual.

2. The method of claim 1, wherein the previously captured motion-based behavior data is stored in a motion-based behavior data database that is associated with the individual.

3. The method of claim 1, further comprising:

authenticating the identity of the individual when the motion-based behavior data is within a threshold of the previously captured motion-based behavior data.

4. The method of claim 3, further comprising:

rejecting authentication of the identity of the individual when the motion-based behavior data is outside the threshold of the previously captured motion-based behavior data; and

rejecting authentication of the identity of the individual when the motion-based behavior data is substantially identical to the previously captured motion-based behavior data.

5. The method of claim 3, wherein the previously captured motion-based behavior data includes motion-based behavior data that is associated with a previous authentication of the identity of the individual.

6. The method of claim 5, further comprising:

storing the input motion-based behavior data in a motion-based behavior data database to be associated with the previous authentication of the identity of the individual when the input motion-based behavior data authenticates the identity of the individual.

7. The method of claim 1, wherein the input motion-based behavior data is associated with a height, a width, and a depth of the defined three-dimension pattern.

8. The method of claim 1, wherein the motion-based behavior data also includes biometric data that is associated with biometric characteristics of the individual generated when the individual executed the plurality of motions to trace the defined pattern.

9. The method of claim 8, wherein the biometric characteristics used to authenticate the identity of the individual are selected from the group consisting of a finger length ratio for each finger relative to each other respective finger and/or a phalanx to metacarpal ratio for each finger.

10. The method of claim 1, wherein the behaviometric characteristics used to authenticate the identity of the individual include a position and/or speed of a hand throughout the trace of the defined pattern and/or the position and/or the speed of each finger throughout the trace of the defined pattern.

11. The method of claim 10, wherein the position and/or the speed of the hand and the speed and/or the position of each finger is captured for each axes of motion.

12. The method of claim 1, wherein the behaviometric characteristics used to authenticate the identity of the individual are selected from the group consisting of:

a sequence of dots included the defined pattern that are traced together by the individual, each limb included in a movement in completing the trace of the defined pattern, and/or an angular position and/or velocity of a wrist over time.

13. A system for securely authenticating an identity of an individual based on a pattern that is traced by the individual, comprising:

one or more processors; and

a memory including instructions that, when executed by the one or more processors, cause the system to;

prompt the individual with a three-dimension authentication template that includes a defined three-dimension pattern for the individual to trace, the tracing of the defined pattern including a plurality of motions;

receive the traced pattern from the individual generated from tracing wherein the plurality of motions generates input motion-based behavior data including behaviometric data associated with behaviometric characteristics of the individual;

obtain previously captured motion-based behavior data associated with tracing of the defined three-dimension pattern by the individual as reference motion-based behavior data;

determine an inter-relationship of the input motion-based behavior data and an inter-relationship of the reference motion-based behavior data including generating a matrix for the input motion-based behavior data set and a matrix for the reference motion-based behavior data set, the matrices each reflecting the impact of pieces of data in the set on other pieces of data in the same set;
