Embodiment Construction
[0033] The present invention is a signature-based two-dimensional code information hiding and authentication method. The present invention first obtains the signature image through a scanner, preprocesses the image, extracts the geometric moment feature of the signature, and then performs training, and obtains Digitally sign and encrypt the threshold value and geometric feature vector, and code it into the quick response code according to the national standard of quick response code to hide the signature information, and then print the two-dimensional barcode with hidden biometric information on various certificates, Provide identification. Then the QR code is identified, decoded, decrypted, and compared with the on-site signature for authentication.
[0034] The present invention has following three technical key points:
[0035] 1) Binarize the signature image by using OTSU, segment the original image by horizontal and vertical projection, and complete the preprocessing of ...

The invention provides an autograph two-dimension code representing and authentication method, belongs to the image processing technical field, and relates to an autograph authentication algorithm and a two-dimensional code coding and recognition algorithm. The autograph two-dimension code representing and authentication method mainly comprise the following steps: firstly, achieving and preprocessing an autograph image through a scanner; then conducting feature extraction on torque features of the autograph image, hiding the autograph feature in the two-dimension code; lastly printing the two-dimension hiding biography feature information on various certificates and providing recognition. The autograph two-dimension code representing and authentication method can combine behavior features of autography with internet of things technology, provides a novel identity authentication and anti-fake method, and contributes to circulation and management of information.
Description
technical field [0001] The invention relates to a signature authentication algorithm and a two-dimensional barcode encoding and recognition algorithm, in particular to a novel identity representation and authentication method based on signature features, which belongs to the field of image processing. Background technique [0002] Nowadays, with the rapid development of the Internet of Things, two-dimensional codes, as an important component of the development of the Internet of Things, have received more and more attention, and are widely used in various fields such as logistics and documents. Signatures have a very long history in China. They have been used as a method of identifying different people from a long time ago. Compared with biological characteristics such as fingerprints and irises, signatures have a good psychological foundation for users and are easily accepted by users. However, directly exposing the signature information does not have concealment and confid...
