Fusion of Fractal Color Watermarking with RSA

Abstract: Now day’s security is an important aspect of life. We require security in every part of communication to transmit our information safely. Here our main aim is to secure the important information hidden in the images, while communicating we are hiding watermark inside the image by using RSA algorithm. To obtain very high image quality we use Fractal color image watermarking. Firstly we encrypt the watermark using RSA and then this encrypted watermark is used to hide inside the image using Fractal color image watermarking. To achieve watermarking we convert RGB into space. Also we are trying to achieve better parameters like PSNR (power signal to noise ratio), BER (Bit error rate) and MSE (Mean square Error).
