Abstract

A method is provided for recording a user'"'"'s handwritten signature through a device including a touch-sensitive surface. The method includes a phase of obtaining a handwritten signature, which includes at least one step of acquiring the handwritten signature on the touch-sensitive surface of the device, delivering an acquired signature and at least one step of recording the acquired signature within a signature-recording space. During the phase of obtaining the handwritten signature, the method includes at least one step of measuring at least one piece of complementary data through the device and at least one step of recording the at least one piece of complementary data.

Claims

1. A method for recording a user'"'"'s handwritten signature through a device comprising a touch-sensitive surface, said method comprising:

a phase of obtaining a handwritten signature comprising at least one step of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one step of recording said acquired signature within a signature-recording space; and

during said phase for obtaining said handwritten signature, at least one step of measuring at least one piece of complementary data through said device and at least one step of recording said at least one piece of complementary data.

2. The method for recording according to claim 1, wherein said step of measuring is implemented prior to said step of acquiring said handwritten signature.

3. The method for recording according to claim 1, wherein said step of measuring is implemented periodically during said step of acquiring said handwritten signature.

4. The method for recording according to claim 1, wherein the method further comprises, prior to said step of measuring, a step of activating a module for measuring said piece of complementary data and, subsequently to said step of measuring, a step of deactivating said module for measuring said piece of complementary data.

5. The method for recording according to claim 4, wherein said module for measuring said piece of complementary data comprises said touch-sensitive surface and said step of activating comprises a step of modifying a value of capacitive sensitivity of said touch-sensitive surface and said step of deactivating said module for measuring comprises a step of restoring the value of capacitive sensitivity of said touch-sensitive surface.

6. A method for authenticating a user'"'"'s handwritten signature through a device comprising a touch-sensitive surface, said method comprising:

a phase of obtaining a handwritten signature comprising at least one step of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one step of comparing said acquired signature with a signature recorded within a signature-recording space; and

during said step of obtaining said handwritten signature, at least one step of measuring at least one piece of complementary data through said device and at least one step of comparing said at least one piece of complementary data with at least one corresponding piece of complementary data associated with said signature recorded within said signature-recording space.

7. A device for recording a user'"'"'s handwritten signature, said recording device comprising:

a touch-sensitive surface;

means for acquiring said handwritten signature on said touch-sensitive surface of said device, delivering an acquired signature; and

means for recording said acquired signature within a signature-recording space;

means for measuring at least one piece of complementary data through said device for recording; and

means for recording said at least one piece of complementary data.

8. A device for authenticating a user'"'"'s handwritten signature, said device comprising:

a touch-sensitive surface;

means for acquiring said handwritten signature on said touch-sensitive surface of said device, delivering an acquired signature; and

means for comparing said acquired signature with a signature recorded within a signature-recording space;

means for measuring at least one piece of complementary data through said device; and

means for comparing said at least one piece of complementary data with at least one corresponding piece of complementary data associated with said signature recorded within said signature-recording space.

9. A non-transitory computer-readable medium comprising a computer program product stored thereon and executable by a microprocessor, wherein the program product comprises program code instructions for executing a method of recording a user'"'"'s handwritten signature through a device comprising a touch-sensitive surface, when the instructions are executed by the microprocessor, said method comprising:

a phase of obtaining the handwritten signature through the device, including at least one step of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one step of recording said acquired signature within a signature-recording space; and

during said phase for obtaining said handwritten signature, at least one step of measuring at least one piece of complementary data through said device and at least one step of recording said at least one piece of complementary data.
