摘要：In the present era, due to the rapid advances in the field of Information Technology digital data can be easily created, copied, processed and distributed freely among unauthorized users. The copyright laws are not sufficient to deal with digital data. Watermarking could be used to protect the authenticity of the owner. In this paper, the Simulink based model for watermark embedding in frequency domain is implemented and simulation results are carried out. The transform used is Discrete Cosine Transform due to its robust nature.
