Digital Watermarking is a technology, to facilitate the authentication, copyright protection and Security of digital media. The objective of developing a robust watermarking technique is to incorporate the maximum possible robustness without compromising with the transparency. Singular Value Decomposition (SVD) using Adaptive Quantization provides this objective of an optimal robust watermarking technique. In this paper watermarking technique has been developed using Adaptive Quantization and
