Document Type and Number:
WIPO Patent Application WO/2021/142973
Kind Code:
A1
Abstract:
An electronic signature validity identification method and system, and an electronic apparatus and a storage medium. The method comprises: respectively acquiring a template signature, and a multi-dimensional feature vector combination set of each Chinese character of a signature to be analyzed (S110), wherein the template signature is a signature which is confirmed to be valid, and the signature to be analyzed is a suspicious signature which cannot be confirmed; according to the multi-dimensional feature vector combination set, acquiring a DTW criterion value, a CNN criterion value, a stroke speed criterion value, a stroke criterion value and a stroke order criterion value of the signature to be analyzed (S120); if the stroke criterion value reaches a standard, respectively assigning a corresponding weight value to the DTW criterion value, the CNN criterion value, the stroke speed criterion value and the stroke order criterion value (S130); and according to the weight value of each of the criterion values, calculating the similarity between the signature to be analyzed and the template signature, and determining, according to the similarity, whether the signature to be analyzed is a valid signature (S140). By means of the method, the problems of traditional manual signature examination being low in efficiency and causing waste of a large amount of manpower and financial resources, and a misjudgement often occurring during manual examination can be solved.
