DIGITAL IMAGE WATERMARKING USING DFT ALGORITHM

Image security is a relatively very young and fast growing. Security of data or information is very important now a day in this world. Information security is most important for the business industries. Embedding information so that it cannot be visually perceived. Embedding information in digital data so that it cannot be visually or audibly perceived. In this paper we review some of the digital image watermarking and techniques and then DFT algorithm is also proposed. In this paper we review the robustness and metrics.
