金融票据混沌水印加密算法研究与实现

Research and Implementation of Chaotic Watermark Encryption Algorithm for Financial Notes

针对金融票据关键信息内容的认证,提出了一种基于混沌水印的加密方法。对关键的数字信息,采用双重水印加密方法,对金融票据进行可见水印和不可见水印的双重加密,提高了信息安全程度。实验结果显示,利用混沌加密算法进行的票据认证,具有较高的实用价值,能有效提高金融系统的安全性。

A chaotic watermark encryption algorithm is proposed for authentication of the key information content in financial notes. Aiming to improve the security of the information,dual watermarking encryption algorithm is adopted for the key numbers. At the same time,visible and invisible dual encryption algorithm is employed for the financial notes. Experimental results show that the note authentication based on chaotic encryption algorithm has a great potential value in practice and improves the security of financial system.
