In this research paper I have proposed the method of an efficient data hiding approach on digital color image for secret communication. The method is applicable for confidential data transfer, secret communication, copyright protection for digital media and military purpose. Steganography process is used for this. Steganography is the process of hiding secret information behind the original cover file. This file may be audio, video or image file. In this system the digital image is taken as input image and preprocessing of input image is done with the help of MATLAB. Any noise present in image is detected and removed in the image preprocessing technique. A given input image is converted into three different planes i.e. red, green and blue plane. After the plane separation embedding process takes place. Also one password is added at the time of embedding process as well as data extraction process, so that no one can easily hack the data. Chaos algorithm is used for data encryption. After the embedding process stego image is formed. In the data extraction process we have to get back original information. So that Chaos decryption algorithm is used to retrieve secret data and cover image. The primary idea of this project is to increase data hiding capacity and reduce image quality degradation.
