Research On Traitor Tracing Technology Of Digital Fingerprinting

Nowadays, people pay more and more attention to copyright protection of digital contents with the rapid development of electronic business services, and cryptography is one of the important solutions to this problem. How to apply modern cryptography to the copyright protection of digital contents is the focus of this dissertation, in which the traitor tracing problem of digital fingerprinting technology is researched in order that the issue of digital contents is run by natural commercial format. Following are the main results of this thesis: Introduce the origin, evolvement and states of digital fingerprinting technology and traitor tracing, expatiate the relation of the cryptography and digital fingerprinting technology and traitor tracing. Introduce the conception of information, digital fingerprinting and traitor tracing simply, explain the terms in common use, summarize the existing results of the research, analyze and discuss the strongpoints and shortcomings of all kinds of traitor tracing schemes. Analyze the performance of the existing traitor tracing schemes, design and develop a traitor tracing scheme, with the charateristics of asymmetry, non-repudiation, full frameproof and anti-linear-attack.
