Abstract
Recently, by the development of digital technology, it is creating variety multimedia contents and the contents producer can make high quality of audio and video, By the development of internet and communication technology it is possible to connect and distribute these contents to the world. According to the development of these technology, some problems are occurred as like a illegal copying, a illegal distribution and infringe author's authority et al. So, for the solution of these problems, some methods were proposed as like watermarking which inserts the information of authority to the contents and the ciphering for authentication to DRM which prevents a illegal copying using RSA.
In this paper, the author used BIBD code into the bit-plane of image contents for DRM with RSA, and implemented RSA block on FPGA.
In whole proceeding, multimedia fingerprint based on BIBD code is inserted to the image contents. Among the decoding proceeding, the author has experimented with the consideration of the transmission and the image transformation.
As a results, the author confirmed that the detection ration of the inserted multimedia fingerprint code is 60% with AWGN 7dB upper and completely 100% with AWGN 10dB upper.
For the external attack of image using stirmark benchmark, 7dB of AWGN is inserted to the image. The inserted multimedia fingerprint code is detected 60% upper from PSNR 30, 40, 70 and 80 of stirmark attacks.
For the experiments, the author implemented RSA H/W block using Altera Quartus II and Altera Cyclone II FPGA. And for the simulation the author used Matlab, Visual C++, Maple, Modelsim and Synopsys.
