Estimation of multimedia fingerprinting image

In this paper, the author presents the estimation method of the multimedia fingerprinting code base on BIBD and investigates PSNR of the experimental images according to BIBD code length. Fingerprinting code has become a promising approach to increase the intensity of multimedia content protection. Through an experiment with 7bits fingerprinting code, in which 91 codes on AND attack, 63 codes on OR attack and 7 codes on EXOR attack could not be used for the collusion attack code. Fingerprinting code is inserted into digital image content. And then through the processing of gray level and Y component of the experimental images, it conforms to that PSNR was 86dB when the fingerprinting code was 22bits.
