An Efficient Approach of Sensitive Area Watermarking with Encryption Security

Recently in the field of watermarking there are lots of facilities in communication, transmission and changes of data or information. There are lot of digital watermarking techniques have been made and implemented to stop the illegal use of the digital multimedia images or data. Robust and reversible watermarking technique is one of them. In this paper, we propose a reversible visible watermark technique, which embeds data into images to create a watermark. This paper tries to simply calculate n1,n2,n3 three variable with the help of key to achieve the digital watermark without any complex calculations and calculate the PSNR ,robustness and capacity of colored image. A reversible watermarking technique is used to embed the watermarking data, which can be used to recover the main images, into the watermarked images.
