A Modified Image using DES Algorithm – A Review

Image encryption is distinct from text encryption. Normal text encryption algorithms are not work efficiently onmultimedia objects. To increase security of multimedia data we propose a novel technique. In this paper, we propose anovel scheme to encrypt image object to protect it from external attacks in transmission. This method is based on DataEncryption Algorithm and can be used in data parallel fashion to reduce the time required time to encrypt and decryptimage so that we can attain the purpose of high speed. The method is implemented by block cipher method. Key generationis done using amplitude modulation technique and provides more security against attacks. Pixels of image are rearrangedand algorithm is applied on the basis of channels. Basics are very much similar to DES algorithm with some new schemesrelated to image processing. Significant increment in security is expected to be achieved in the proposed method.
