METHOD OF GENERATING ANTI-COLLUSION FINGERPRINT CODES USING

摘要

Disclosed herein is a method of generating anti-collusion fingerprint codes using a (n^a, n^2a-2, n^a-1, n, 0, 1) GD-PBIBD. The fingerprint codes are generated using computer equipment that executes a program for executing a program for generating the fingerprint codes. The method includes step 1 of receiving an arbitrary prime number n and an arbitrary integer a larger than 3, step 2 of generating an nxn index matrix, step 3 of generating n nxn type_i matrixes, step 4 of generating an n²xn² matrix using the nxn index matrix and the nxn type_i matrixes, step 5 of generating an n^axn^2a-2 matrix, and step 6 of extracting one arbitrary column from the n^axn^2a-2 matrix.
