基于银行卡信息安全的数字水印方案

Digital watermarking scheme based on information secure of bank card

近年来研究的数字水印技术主要运用在保护版权和电子产品等方面,针对银行卡存在的信息安全问题,提出一种数字水印技术和IC芯片结合的新方案来保护银行卡的安全,防止被非法复制。方案中的银行卡是以芯片作为介质的,与磁条卡相比,芯片卡安全性高,卡内敏感数据难以被复制。利用现在已经存在的实践和理论知识相结合的主要研究方法,得到实际需要的防复制水印和IC芯片。给出了方案设计流图,仿真实验结果表明,该方法可以实现防复制功能。

In recent years the digital watermark technology is mainly used in the protection of copyright and electronic products etc.To the bank of information security analysis suggested a new scheme,which digital watermarking technology and IC chip combine to protect the safety of bank card,prevent illegal copy.In the scheme,the chip in the bank card serve as a media,compared with the card of magnetic stripe,the chip cards has higher security,the sensitive data in the card is hardly copied.The main method of practical and theoretical knowledge combining is used,which already exists now,the copy protection watermarking and IC chip of the actual need is gotten.The design of flow chart and the simulation result are obtained.It is indicated the method can realized the function of prevent replication.
