Abstract

Embodiments of the invention are generally directed to systems, methods, devices, and machine-readable mediums for implementing gesture-based signature authentication. In one embodiment, a method may involve recording a first gesture-based signature and storing the recorded first gesture-based signature. Then the method compares the first gesture-based signature with a second gesture-based signature. Then the method verifies the first gesture-based signature as authentic when the first gesture-based signature is substantially similar to the second gesture-based signature.

Claims

1. A method, comprising:

recording a first gesture-based signature;

storing the recorded first gesture-based signature into a first storage location;

comparing the first gesture-based signature with a second gesture-based signature already stored in a second storage location; and

verifying the first gesture-based signature as authentic when the first gesture-based signature is substantially similar to the second gesture-based signature.

2. The method of claim 1, further comprising:

registering the second gesture-based signature prior to recording the first gesture-based signature, wherein the registering comprises

recording the second gesture-based signature a plurality of times;

calculating an acceptable variability range of the second gesture-based signature; and

storing a version of the second gesture-based signature in the second storage location in response to the version at least falling with in the calculated variability range.

3. The method of claim 1, further comprising:

associating a text-based password with the second gesture-based signature; and

providing the text-based password in response to a password request when the first gesture-based signature has been verified as authentic.

4. The method of claim 1, wherein the verifying includes a relative temporal element that at least requires the first gesture-based signature to be recorded in a first period of time, the first period of time being within a predetermined maximum discrepancy of time in comparison to a second period of time, the second period of time comprising the amount of time to record the second gesture-based signature.

5. The method of claim 4, wherein the verifying further includes comparing data recorded at a plurality of intervals of time associated with the first gesture-based signature with corresponding data recorded at the plurality of intervals of time associated with the second gesture-based signature.

6. The method of claim 1, wherein the first gesture-based signature includes at least one of a touch-screen glyph, a spoken phrase, and a movement in three-dimensional space.

7. A machine-readable medium having stored thereon instructions, which if executed by a machine causes the machine to perform a method comprising:

recording a first gesture-based signature;

storing the recorded first gesture-based signature into a first storage location;

comparing the first gesture-based signature with a second gesture-based signature already stored in a second storage location; and

verifying the first gesture-based signature as authentic when the first gesture-based signature is substantially similar to the second gesture-based signature.

8. The machine-readable medium of claim 7, wherein the performed method further comprises:

registering the second gesture-based signature prior to recording the first gesture-based signature, wherein the registering comprises

recording the second gesture-based signature a plurality of times;
