Novel Method of Highly Secured Image Encryption Technique

A major challenging issue in the today’s internet is the secure transmission of the images. There are methods that are been developed for secure transmission, but there is every possibility for acquiring the image and to change the content in the image. Most of the methods are complex and diesign is also very difficult. In this paper, we proposed a novel method for transmitting the image over the internet. The proposed method is based on original image to be sent, a cover image which is also called as reference image, three secret keys or passwords. It’s like a triple protection with the help of secret keys and at the same time cover image is used to encode the pixel values in to index values. After images decryption, the image quality has been verified with the original image for the image quality assessment. In the proposed method it is very difficult to retrieve the original image from the encrypted image.
