An Effective Algorithm of Encryption and Decryption of Images Using Random Number Generation Technique and Huffman Coding

Data security has become most important aspect while transmission of data and storage. The transmission and exchange of image also needs a high security. Cryptography is used to maintain security. In this paper, the authors implemented security for image. They have considered an image, read its pixels and convert it into pixels matrix of order as height and width of the image. Replace that pixels into some fixed numbers, generate the key using random generation technique.
