Improved DCT-Based Watermarking through Particle Swarm Optimization

With the widespread use of computers and Internet, users have more chances to use multimedia data and digital contents. As a result, illegal reproduction of digital information started to pose a real problem. Digital watermarking has been regarded as an effective solution to protect various kinds of digital contents against illegal use. In this paper, a watermarking technique which applies the discrete cosine transformation and particle swarm optimization is presented. Experimental results demonstrate that the proposed technique is able to withstand a variety of attacks.
