Fingerprinting Algorithm Based on the Figure’s Collusion Data Base

Under the application occasion of using data base as the soft products publication, there should be corresponding safety system, which could abstain the privacy actions from the betray users. A privacy tracing and solution resolution is raised in this thesis based on the digital fingerprinting relationship data base. Data fingerprinting database, which combined by patent watermarking and user’s fingerprint in chaotic binary sequence, is imbedded into the data base under the control of encryption key. Based on the chaotic binary sequence’s randomness, to abstract the fingerprinting and trace the betrayer. The plan has strong conclusion safety, at the same time lower the fingerprinting inspection and betray tracing algorithm complexity. The thesis describes the data base fingerprinting encode, embedment, fingerprinting inspection and abstraction algorithm, analyzes the algorithm’s robustness and betray tracing ability, and has experiment testimony.
