摘要

针对关系数据库数据在使用时必须要求真实性的原则

提出一种可用于关系数据库的可逆水印技术方案

该方案可以从无篡改的水印数据库中无损地恢复原始数据

该水印算法只有拥有密钥和其他秘密参数的用户才可以完全恢复原始数据.通过算法分析和实验分析

该水印方案还具有不可见性和可行性等特点.

Abstract

Now people are concerned about that how to protect the digital media copyright more and more.And for relational data

that how to protect its ownership and not to affect its usage becomes a difficult problem.A reversible watermarking scheme for relational databases on numerical attribute is proposed.The basic idea of the scheme is to embed the watermark information into relational databases with exclusive or under some secret parameter

and the original data can be recovered losslessly from the unmodified watermarked relational databases with exclusive or under the same secret parameter.Only the person who owns the private key and other unique parameters can recover them perfectly.Through the algorithms and some experiments analysis

the scheme is proved to be invisible and feasible.
