Abstract
A method and system of signature verification that includes receiving a signature-in-question, extracting at least one of an image of the signature-in-question and a trajectory of the signature-in-question from the received signature-in-question, accessing a reference signature, extracting at least one of a reference image and a reference trajectory from the accessed reference signature, comparing the at least one of the image of the signature-in-question and trajectory of the signature-in-question to the at least one of the reference image and reference trajectory, and determining whether signature-in-question is authentic based on the comparison.
Claims21
A method of signature verification, the method comprising:
- receiving a signature-in-question;
- extracting at least one of an image of the signature-in-question and a trajectory of the signature-in-question from the received signature-in-question;
- accessing a reference signature from a reference signature storage, the reference signature storage including at least one of a reference image and a reference trajectory;
- extracting at least one of the reference image and the reference trajectory from the accessed reference signature storage;
- and
- comparing the at least one of the image of the signature-in-question and trajectory of the signature-in-question to the at least one of the reference image and reference trajectory.
A signature verification system comprising:
- a data receiver;
- an updatable data repository functionally coupled to the data receiver;
- a display device functionally coupled to the data receiver;
- a processor operatively coupled to the data receiver, to the updatable data repository and to the display device;
- and
- a memory coupled to the processor, the memory storing instructions that, when executed by the processor, perform a set of operations comprising:
- receiving, at the data receiver, a signature-in-question;
- extracting, via the processor, at least one of an image of the signature-in-question and a trajectory of the signature-in-question from the received signature-in-question;
- accessing a reference signature storage of a reference signature, the reference signature storage including at least one of a reference image and a reference trajectory;
- extracting, via the processor, at least one of the reference image and the reference trajectory from the accessed reference signature storage;
- and
- comparing, via the processor, the at least one of the image of the signature-in-question and trajectory of the signature-in-question to the at least one of the reference image and reference trajectory.
