Method for authenticating a signature
First Claim
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 the handwritten signature comprising at least one act of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one act of recording said acquired signature within a signature-recording space;
during said phase of obtaining said handwritten signature, at least one act of measuring at least one piece of complementary data representing a position of a hand of the user through said touch sensitive surface, said hand being used for writing said signature, wherein the complementary data represents a trigonometrical position of the hand around an axis of a stylus held by a user and used for writing the handwritten signature during the act of acquiring said handwritten signature; and
at least one act of recording said at least one piece of complementary data.

8. 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 act of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one act of comparing said acquired signature with a signature recorded within a signature-recording space; during said act of obtaining said handwritten signature, at least one act of measuring at least one piece of complementary data representing a position of a hand of the user through said touch sensitive surface, said hand being used for writing said signature, wherein the complementary data represents a trigonometrical position of the hand around an axis of a stylus held by a user and used for writing the handwritten signature during the act of acquiring said handwritten signature; and at least one act 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. - View Dependent Claims (9, 10, 11, 12, 13)

14. 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; 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 representing a position of a hand of the user through said touch sensitive surface, said hand being used for writing said signature, wherein the complementary data represents a trigonometrical position of the hand around an axis of a stylus held by a user and used for writing the handwritten signature during the acquiring of said handwritten signature; 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.

15. 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 for authenticating a user'"'"'s handwritten signature through a device comprising a touch-sensitive surface, when the instructions are executed on a computer by the microprocessor, said method comprising:
-
a phase of obtaining a handwritten signature comprising at least one act of acquiring said handwritten signature on said touch-sensitive surface of said device delivering an acquired signature and at least one act of comparing said acquired signature with a signature recorded within a signature-recording space; during said act of obtaining said handwritten signature, at least one act of measuring at least one piece of complementary data representing a position of a hand of the user through said touch sensitive surface, said hand being used for writing said signature, wherein the complementary data represents a trigonometrical position of the hand around an axis of a stylus held by a user and used for writing the handwritten signature during the act of acquiring said handwritten signature; and at least one act 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, said at least one piece of complementary data, without directly coming from the signature, being related to the signature by a link of connectivity directly derived from the user.
