Novel Algorithm of Collusion Secure Fingerprint Coding and Traitor Tracing for Relational Database
一种合谋安全的数据库指纹编码与盗版追踪算法

It is necessary to provide secure mechanism to resist the piracy from the renegade users when databases are distributed as software products.In this paper,a scheme of traitor tracing for rational database based on digital fingerprinting is presented.In the proposed scheme,the database fingerprints are composed of copyright watermarks and user's fingerprints by using the chaos binary sequence,and are embedded into the database under the control of the secret key.The fingerprints are extracted and the traitor...
