Handwriting verification apparatus and handwriting verification method

Abstract

The invention provides a handwriting verification apparatus. The apparatus comprises a parameter storage unit for storing preset characteristic parameters of hand-written handwriting, an obtaining unit for recognizing a user's hand-written handwriting and obtaining the characteristic parameters of the hand-written handwriting, a parameter comparison unit for making a comparison between the characteristic parameters of the hand-written handwriting and the preset characteristic parameters, and a determination unit for determining whether the characteristic parameters of the hand-written handwriting match the preset characteristic parameters, in case of matching, determining that the hand-written handwriting is successfully verified, and in case of unmatching, determining that the hand-written handwriting fails to be verified. The invention also brings forward a handwriting verification method. By using the technical scheme provided by the invention, original handwriting of hand-written input can be verified, and the verification demands of client groups demanding hand-written signing approval are satisfied.

Description

technical field [0001] The invention relates to the technical field of handwriting verification, in particular to a handwriting verification device and a handwriting verification method. Background technique [0002] With the popularization of electronic products and the improvement of users' demand for information security, coupled with the continuous development of image processing technology, signature anti-counterfeiting has become an important means to protect information security and property security, and the application of electronic signature is becoming more and more extensive. , The importance of anti-counterfeiting verification technology for signing and approval is self-evident. [0003] The existing anti-counterfeiting verification technology is mainly an encryption algorithm. The encryption algorithm generally adopts the RSA algorithm or the DSA algorithm, and the verification message adopts the MD5 algorithm or the SHA-1 algorithm. Through the existing encryp...

Problems solved by technology

[0003] The existing anti-counterfeiting verification technology is mainly an encryption algorithm. The encryption algorithm generally adopts the RSA algorithm or the DSA algorithm, and the verification message adopts the MD5 algorithm or the SHA-1 algorithm. Through the existing encryption and decryption technology, electronic files in a fixed format can be effectively verified. processing, but the existing technology can only perform mechanical judgment on fixed fonts, and for the customer group of handwritten signatures, different users have different writing methods and habits, and the fonts input by handwriting are not fixed , the existing technology cannot meet the original handwriting verification requirements of the customer group for handwritten signatures
