Images have a significant role in communication, entertainment and business etc. Images may convey confidential information, so various image encryption algorithms ensure security of secret images. The correlation coefficient in encrypted image is an important security criterion to measure the level of security of encrypted image. Various factors can affect the correlation coefficient in the encoded image. So, this work reveals the effect of image encryption method and the size of an image on correlation coefficient in the corresponding encrypted image. General TermsData Security, image encryption, image processing.

The rapid development of communication technology due to the global spread of the internet and the digital information revolution has given rise to a huge increase in the use and transmission of multimedia information. Encryption technology is studied in this paper, and a new image encryption algorithm based on correlation of pixels is proposed. The main goal of this paper is security management. Researchers have proposed incompatible methods to encrypt images. So, here we go through a new way of image encryption and decryption using block based image encryption using affine transform. First of all the plain image is divided into fixed size blocks. All these blocks then shuffled according to the proposed algorithm and we get a block shuffled image. At last the encrypted algorithm of affine is used iteratively for each of the pixels. It uses the keys for the purpose of encryption.

“…However, these techniques are capable to encrypt text data nevertheless deficient in image encryption [2]. Images are different from text data due to bulky data, high redundancy and strong correlation between pixels [3,4,5,6]. So there is a need of encryption technique that is suitable for images [3,4,5].…”

Images are gaining popularity in communication, entertainment and business etc. Some images can have confidential information so the security of these confidential images is a crucial issue. There is the image encryption technique that uses a one-dimensional random scrambling and provides security to secret images. The drawback of this technique is that it does not produce different histogram from the histogram of original image even after encryption procedure and this unchanged histogram reveals useful information about the original image. In this paper, an image encryption method is proposed that eliminates this drawback and provides better security than algorithm that uses one dimensional random scrambling. General TermsCryptography, image security, image processing.
