基于嵌入式TCP/IP的在线签名数据采集系统
首发时间:2007-05-28
摘要:在线签名识别在银行金融系统及个人身份识别等领域正引起广泛关注。笔迹信息的采集是在线签名识别算法的基础,设计了一种基于嵌入式TCP/IP的在线签名数据采集系统,该系统以C8051F020 SOC单片机为核心,实现了在线签名数据的实时采集,并在有限的单片机资源基础上移植嵌入式TCP/IP协议栈,通过以太网接入Internet,将采集到的签名信息准确及时地上传到远程认证服务器。

On-line Signature Data Acquisition System Based On the Embedded TCP/IP
Abstract:On-line signature verification is attracting extensive focus in the fields of banks, financial systems and personal identify verification. Handwriting data acquisition is the base of the arithmetic of on-line signature verification. It designs a data acquisition system of on-line signature based on the embedded TCP/IP. The system takes C8051F020 MCU as core, has realized real-time data acquisition of on-line signature, and transplants the embedded TCP/IP protocol stack based on the limited MCU resources. Accessed to the internet over the Ethernet, the accurate signature information will be uploaded to the remote authentication server in time.
Keywords: on-line signature data acquisition TCP/IP C8051F020 RTL8019AS
