Abstract


In today's information-oriented society , more and more frequently to the Internet and other open network - based e-commerce activities , personal electronic authentication is the inevitable trend of future development of society . The development of network information technology personally identifiable information security has become a key issue for the society . Identification is a problem faced by the protection of information security , compared with the traditional identification methods , biometric identification has been more widely used because of the security is good , portable, easily lost and forgotten . Line signature recognition is a person 's biometric identification technology , computer online signature image , stroke , speed and pressure real specimen signatures , the authenticity of the signature to the real-time identification . The focus of this study is based on four-wire resistive touch screen online signature data acquisition system hardware and software design . Acquisition system hardware design includes data acquisition module, display module, USB communication module and the control module of the four components . Its working principle is through a four-wire resistive touch screen collected a sampling frequency of 200Hz signer's handwriting , and passed to the MCU in real time . The MCU data after simple processing to the display module the handwriting image restoration , for the reference of the signer . After this data through the USB interface to the PC to display and save , described in detail on the basis of the overall circuit design ideas , also introduced the four-wire resistive touch screen and touch screen controller ADS7846 control mode , the LCD controller SED1335 works and USB bus control chip PDIUSBD12 work. The system software is designed mainly contains firmware, procedures and PC procedures of two major application development . The application shows that the design of online signature data collection and transmission system acquisition of high precision , stable and reliable , anti-interference ability , stable and reliable data for subsequent matching signature recognition processing .
