Digital Images and video encryption plays an important role in today's multimedia world. Many encryption schemes have been proposed to provide security for digital images. Usually the symmetric key ciphering algorithms are used in encrypting digital images because it is fast and use the techniques for block and stream ciphers. Data Encryption Standard is symmetric key encryption algorithm. In spite of the successful cracking of the data encryption standard by massive brute force attacks, data encryption standard algorithm is an entrenched technology and still useful for many purposes. In this paper, the authors use some of the image quality encryption measuring factors to study the effect of data encryption standard algorithm in image ciphering.
