An Optimized Image with Digital Multimedia Files Hiding Audio, Video by Using DES Algorithm

Steganography is the process of hiding information for the purpose of communication in sender to receiver. All kinds of stegano files are send, such as audio, video, text. Security of data can be achieved by implementing steganography techniques. All of the existing steganography techniques use the digital multimedia files as a cover medium to conceal secret data. Audio and video file use as a cover medium in steganography because of its larger size compare to other carrier's file such as text, image. So there are more possibilities to hide large amount of data inside digital audio, video file. Signals Various file formats are can be used, but digital images are popular because it is frequency on the internet. It also supports steganography in audio files. Intruders are easily hack the information because it is not encrypted, so we propose the hiding secret information in images and audio to sender and receiver, it is the steganography hiding secret information in image, it is the process to encrypt the message using secret key and then sends it to the receiver. The receiver then decrypts the message to get the original one. Hiding the text message in an image file, video and audio WAV file. Encryption of the same message, so as to support more secure steganography. The decoding of the message, decryption and source message retrieval are also supported.so, this steganography techniques are user friendly.
