Abstract
A signature verification method based on image analysis includes capturing a handwriting data of a signatory performing a signature process by a signature capture device; capturing an image data of the signatory performing the signature process by an image capturing device; obtaining feature information from the image data; comparing the handwriting data and the feature information with authentication reference data to generate a comparison result; and determining authenticity of the signature process based on the comparison result.
Claims18
A signature verification method based on image analysis, comprising:
- capturing a handwriting data of a signatory performing a signature process by a signature capture device;
- capturing an image data of the signatory performing the signature process by an image capturing device;
- obtaining feature information from the image data;
- comparing the handwriting data and the feature information with authentication reference data to generate a comparison result;
- and
- determining authenticity of the signature process based on the comparison result.
A signature verification system based on image analysis, comprising:
- a signature capture device, configured to capture handwriting;
- an image capturing device, configured to capture images;
- a processing unit, coupled to the signature capture device and the image capturing device;
- and
- a storage unit, coupled to the processing unit and storing a program code, wherein the program code instructs the processing unit to execute a signature verification method, and the signature verification method includes:
- using the signature capture device to capture a handwriting data of a signatory performing a signature process;
- using the image capturing device to capture an image data of the signatory performing the signature process;
- obtaining feature information from the image data;
- comparing the handwriting data and the feature information with authentication reference data to generate a comparison result;
- and
- determining authenticity of the signature process based on the comparison result.
