Research On Digital Fingerpriting Of Information Hinding

With the rapid development of new IT technologies and electronic commerce, intellectual property for digital content has been a crucial issue. This problem also becomes an internal motive for information hiding. Fingerprinting and watermarking are the most important two main methods. Traitor tracing is a kind of broadcast with traceability, which falls into the category of fingerprinting. This paper will focus on fingerprinting, mainly including the following contents: Introduce the background and significant of studying information hiding and digital fingerprinting, and their relation with cryptology. Specify the class and model of information hiding, and then depict the features, development and application of this technology. The requirement, peculiarity and current conditions of fingerprinting are also introduced. Two typical fingerprint schemes are proposed. A scheme based on the blind signature is introduced. A traitor tracing scheme based on the Chinese remainder theorem is introduced. Propose another scheme based on the B-F scheme.
