vhdl code for watermarking

Digital watermarking technology is a frontier research field and it serves an important role in information security. Digital Watermarking is a technology of embedding watermark with intellectual property rights into images, videos, audios and other multimedia data by a certain algorithm. The basic characteristics of digital watermark are imperceptibility, security, reliability, low complexity of watermarking algorithm and security of the hiding place. According to the analysis of the definition and basic characteristics of digital watermarking technology, the system model of digital watermarking is given. The system consists of two modules which are watermark embedding module and watermark detection and extraction module. In this paper we employed the two dimension wavelet transform on the Windows platform by using VHDL program language to embed the watermark. VHDL implementation is done to save resources and for faster operation. The embedding and retrieving of watermark using this is faster than that done through high level programming languages. The experiment result shows that the digital watermark is non-perceptible; the watermark information can be extracted even if it has been attacked, and the expected effect can
be achieved.
