Framework of multimedia forensic system

In this paper, framework composition for the design of multimedia forensic system is composed. Fingerprinting code used in the forensic marking of multimedia content is based on BIBD code characteristics {v,k,λ parameters} and generated dynamically. A firing vector of the fingerprinting code of the content user uses the feature point that is detected from audio, image and video content itself. It dynamically generated fingerprinting code for forensic marking is inserted into a content, and then the content is distributed. If a detected fingerprinting code from the distributed content is not in the user fingerprinting codebook, then this code is assumed a colluded code. And using a resiliency{λ parameter} which BIBD code has, it could be traced the user who attended in a collusion attack. Again, new fingerprinting code will be regenerated using a firing vector by another feature point in the content. Then it is reinserted into the content and redistributed. Thus, it cut off the illegality distribution, and an intellectual property right is protected.
