摘要：In our digital society, the major source of communication is digital media such as images, video, audio or text. So impersonate and copyright protection of digital content remains an indispensable problem across the globe. To deal with this problem, digital watermarking has become advantageous solution for providing ownership of digital content. In this paper we have developed a robust DCT based image watermarking using fusion of Fuzzy Logic and Neural Networks. In this technique, we embed and extract biometric watermark using the fuzzy-neuro based watermarking in middle frequency band. This paper illustrates a modified algorithm for DCT based digital watermarking. To demonstrate working of the aforesaid algorithm, an experimental system is also developed with different input and displays the comparison of the PSNR values for them.
