摘要: 在外包数据库运行模式下,由第三方提供的数据库服务器处于非信任域,存在数据文件盗版、数据内容篡改等安全风险。构建了一个基于信息隐藏技术的外包数据库版权保护系统,综合运用数字水印、PK工机制与数字证书、数字签名及可信硬件模块USB Key等技术,设计相应的水印协议,实现对外包数据库的版权保护。与传统的以数据加密、数字签名等方法为主要技术手段的解决方案相比,它具有冗余存储量及网络附加流量小、隐蔽性好、验证信息难以删除等优点。
关键词: 外包数据库,信息隐藏,数字水印,版权保护,USB Key
Abstract: In outsourced database scheme, since the database server, which is provided by the third part, is not in the trust domain, the data files may be pirated, and the data contents may be tampered with. A copyright protection system for outsourced database using information hiding technique was built, which was based on algorithms of database watermarking, as well as their corresponding protocols, and was combined with technologies of PKI, digital signature and USB Key. Compared with traditional solutions which of data encryption or digital signature, the copyright protection system for outsourced database based on information-hiding possesses advantages of less redundant capacity either for storage or for communication, better imperceptibility, and validation information harder to be removed.
Key words: Outsourced database, Information hiding, Digital watermarking, Copyright protection, USB Key
