As technologies in multimedia are growing quickly, a huge amount of multimedia data is produced and broadcasted. The internet also permits the extensive allocation of data. Because of this it becomes very simple to duplicate, alter and reproduce digital information. This becomes a serious safety and security issue and it became mandatory to ensure protection because. Of its confidentiality which may tolerate some crucial information that should be not or partly be accessed by the users which are general. The second issue with digital videos and information is that small alterations can be made with the help of extensively available minute devices, again putting the safety issue on stake. Cryptography focuses on protecting such crucial information being generated by digital devices and then being transmitted. This paper compares the AES, DES and Present cryptographic algorithms. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
