Image Encryption and Decryption Algorithm using XOR Operator

As the result of the rapid development of technology, information science has become much easier, and therefore the problem of information security is growing. This paper deals with the secretiveness of images, so image encryption is that the latest trend in information caching. The novelty of the work lies in generating crucial images for encryption. The crucial image is then created with the assistance of a secret alphanumeric key. Each alphanumeric key will have an 8bit value generated by the binary key table. The challenge is to return up with an image encryption algorithm that is simple yet safe, with featherweight computer processing. This encryption algorithm which mixes Playfair cipher and therefore the Vigenere cipher gives better results. An experiment showed a correlation between the precipitation of the image after encryption and its decline. Supported the standard of quality of encryption, the speed of change of image pixels was high enough for the cipher image to be difficult to spot. The image is meant to be more distorted in this fashion. The deciphered image is obtained by applying the backward process.XOR technique is used in the present paper, for security analysis using XOR technique is an effective method of scrambling, in visual component which may be used as an important visual cryptography. For secure transmission of an image XOR cipher is a best technique.
