Method and system for tracking illegal distributor and preventing illegal content distribution
First Claim
1. A system for tracking an illegal distributor and preventing an illegal content distribution, the system comprising:
- a forensic mark generator configured to receive content and a content identification code from a content providing apparatus to generate a forensic mark by combining the content identification code, a distributor identification code, and a user identification code, wherein the forensic mark generator includes;
a first balanced incomplete block design (BIBD) matrix generation module configured to receive a total number of distributors and a number of first detectable ones in collusion to generate the distributor identification code;
a second BIBD matrix generation module configured to receive a total number of users and a number of second detectable ones in collusion to generate the user identification code;
a forensic mark database configured to store the generated forensic mark and store content transaction information when requested to transmit the content information by a content utilization apparatus afterward;
a forensic mark insertion unit configured to insert the forensic mark into the content;
a content database configured to store the content into which the forensic mark has been inserted; and
a content transmitter configured to transmit the content into which the forensic mark has been inserted to the content utilization apparatus.
