Abstract: Disclosed herein is a method of generating anti-collusion fingerprint codes using a (na, n2a−2, na−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 n×n index matrix, step 3 of generating n n×n type_i matrixes, step 4 of generating an n2×n2 matrix using the n×n index matrix and the n×n type_i matrixes, step 5 of generating an na×n2a−2 matrix, and step 6 of extracting one arbitrary column from the na×n2a−2 matrix.
