Abstract

The invention discloses an authentication system based on a writing pen-strength identification. The authentication system comprises a single chip, a touch screen control module, a resistor touch screen and an upper computer procedure module. A first output end of the single chip is connected with the resistor touch screen through the touch screen control module, a second output end of the single chip is connected with the upper computer procedure module, the single chip and the resistor touch screen jointly complete acquisition of pen-strength information, a serial port is in data communication with the computer, the upper computer procedure module establishes a pen-strength information database, and finally authentication of a user is completed through a matching alignment algorithm. With combination of a handwriting identification technology and authentication of writing strength, the authentication system based on writing pen-strength identification improves accuracy of authentication.

Description

technical field [0001] The invention relates to an identity verification system, in particular to an identity verification system based on recognition of writing strokes, and belongs to the technical field of single-chip microcomputer control. Background technique [0002] In today's information society, people pay more and more attention to personal privacy, business secrets, and national security. Information needs to be easily read and reliably protected. However, some of today's authentication schemes are not perfect, and even iris and fingerprint recognition, which are considered irreproducible, can be impersonated in extreme cases where criminals obtain body parts such as eyeballs or fingers. Since the writing habits of adults, including the shape, speed, strength and angle of writing, are fixed for a long period of time, the shape of the signature has long been used as the basis for authentication. Chinese characters, in particular, are often used as identification d...
