在线签名认证的数据采集系统设计

在线动态签名认证由于其安全性和方便性，广泛适用于银行金融系统以及个人身份识别等.作为在线签名笔迹的数据采集，对后续认证的准确性显得尤为重要.利用STM32F103C8、触摸屏、触摸屏控制器TSC2046和SD卡，实现了对在线笔迹包括压力在内的3维数据采集以及存储.实验结果表明，设计的在线签名数据采集系统精度高，稳定可靠，抗干扰能力强，具有很好的认证效果.

Data Collection System of on-Line Signature Verification

Due to its safety and convenience,online signature verification is especially useful for banking and financial system and personal identification.So the basis of online signature verification data collection of handwriting is very important for followed verification’s accuracy.STM32F103C8,touch screen and touch panel controller TSC2046 and SD card are used to collect and save three-dimensional data of handwriting including stress information.The experimental results show that,the design of the online signature data acquisition and transmission system for high precision,stability and reliability,strong anti interference ability,has the very good identification effect.
