    Digital fingerprinting , a copyright protection tech-nique of multimedia data , is considered. For digital finger-printing , measures against collusion attacks , where several fingerprinted copies of the same content are mixed to disturb their fingerprints , should be taken. In this paper , we propose a shortening method of collusion-secure fingerprinting codes based on finite geometries , which reduces the code length with keeping the number of codewords and the codes' resilience. We also propose a concatenated coding method which combines a conventional collusion-secure fingerprinting code and an error correcting code for increasing the coding rate , ue to the new fingerprinting codes , the system can deal with a larger number of users to distribute a digital content.
