With the increasing need of sensitive or secret data transmission through public network,security demands using cryptography and steganography are becoming a thirsty research area of last few *** two techniques can be merged and provide better security which is nowadays extremely *** proposed system provides a novel method of information security using the techniques of audio steganography combined with visual *** this system,we take a secret image and divide it into several subparts to make more than one incomprehensible sub-images using the method of visual *** of the sub-images is then hidden within individual cover audio files using audio steganographic *** cover audios are then sent to the required destinations where reverse steganography schemes are applied to them to get the incomprehensible component images *** last,all the sub-images are superimposed to get the actual secret *** method is very secure as it uses a two-step security mechanism to maintain *** possibility of interception is less in this technique because one must have each piece of correct sub-image to regenerate the actual secret *** superimposing every one of the sub-images meaningful secret images cannot be *** files are composed of densely packed *** high density of data in audio makes it hard for a listener to detect the manipulation due to the proposed time-domain audio steganographic method.
