Video-based Air Signature Authentication Method

Abstract

The present invention provides a video-based aerial signature authentication method, which extracts features of signatures to be authenticated and registered signatures, and respectively obtains track features of signatures to be authenticated and track features of registered signatures; and then traces of signatures to be authenticated Signature authentication is achieved by matching the signature with the trajectory signature of the registered signature. The video-based aerial signature authentication method of the present invention can effectively improve signature recognition accuracy, thereby improving the accuracy and effectiveness of signature authentication.

Description

technical field [0001] The invention relates to the technical field of image processing and analysis, and more specifically, relates to a video-based aerial signature authentication method. Background technique [0002] In recent years, with the rapid development and wide application of biometric authentication technology, users have put forward more and higher requirements for biometric authentication technology, which has led to some new development trends in biometric authentication, such as stronger anti-counterfeiting , higher recognition accuracy, and higher user acceptance. [0003] Although online signature authentication has been rapidly developed and applied, there are still some shortcomings, mainly reflected in the following aspects: [0004] (1) The number of strokes and words in the signature is limited, so it is difficult to accurately grasp when selecting representative features; [0005] (2) At different times, through different writing tools, and under th...

AI Technical Summary

Problems solved by technology

[0004] (1) The number of strokes and words in the signature is limited, so it is difficult to accurately grasp when selecting representative features;

[0005] (2) At different times, through different writing tools, and under the circumstances of changes in psychological and physiological conditions, inconsistencies may be caused before and after the signature. Therefore, compared with other biological characteristics such as fingerprints, the stability is poor and the accuracy rate is low. Low;

[0006] (3) The explicit form of the signature makes some static features of the signature easy to be stolen and forged, so the anti-counterfeiting is affected to a certain extent;

[0007] (4) The dependency condition based on WordPad also makes it have the problem of narrow application occasions

[0008] The above-mentioned problems are areas where online signature authentication faces improvement
