Abstract :
Copyright protection of digital contents becomes more and more important in accordance with the development of digital technology. As a solution of this problem, digital watermark technology is drawing attention and various watermarking methods have been presented. However, it is difficult for us to decide which method is better than others, because the measure for evaluating their performance has not been established yet. We propose a method that evaluates the performance of the correlation-based watermarking technique in the frequency domain.
