Review of Digital Watermarking Techniques

Abstract

Digital watermarking is delicate to various attacks in spatial domain, Hence in most of the watermarking technique’s transform domain is used. This paper takes a survey of such digital watermarking techniques and methods like Discrete cosine transform (DCT), Singular value decomposition (SVD), SVD-DCT, DWT-SVD with different approaches along with their applications, advantages and disadvantages. Further future work and implementation plan is also mentioned in the paper.
