Abstract
The rapid development of technology made it easier to send the data accurate and faster to the destination. The most important factor of information technology and communication is the security of the information. This security can be achieved through steganography. Steganography is art and science of invisible communication. This paper mainly focuses on audio and video steganography. Video Steganography hides secret data within a video and audio steganography deals with hiding secret data within audio. The secret data is first compressed, encrypted and then embed into the cover frames in such a way that eight bits of the secret data are divided into 2, 2, 2, 2 and then embedded into the RGB (Red, Green, Blue) pixel values of the cover frames respectively and the remaining 2 bits are inserted in the next pixel of cover frame and so on. The proposed technique is compared with existing LSB (Least Significant Bit) based steganography and the results are found to be encouraging.
