Now-a-day's great request of net application requires data to be transmitted in a secure manner. Data broadcast in public communication structure is not safe because of interception and improper manipulation by eavesdropper. because the good-looking solution for this trouble is Secret writing, which is the art and science of writing hidden messages in this way no one, apart from the source and intend destination, suspects the existence of the message, a form of safety from side to side darkness. auditory Secret writing is the scheme of hiding the existence of secret information by conceal it into one more standard such as auditory file. The rapid spread in digital data usage in many real life application contain urged newly and effectual ways to ensure the security. The efficient secrecy can be achieved, at least in part, by implementing Secret writing techniques. The goal of Secret writing technique is to obtain secure and robust way to conceive high rate of secret data. We focus on digital audio steganography which has emerged as a prominent source of data hiding across narrative telecommunication technology such as enclosed tone over IP, audio conferencing, etc., In this paper, we are hiding an image into an audio signal. The image that needs to be transmitted securely is encrypted using Secure force algorithm. The resultant will be the encrypted image which is used to hide into the audio signal. Then the audio is then transmitted through wireless network. At the receiver end the embedded audio signal is received, from which the audio and image are decoded. The image recovered from the audio signal is decrypted to obtain the original image. This method works as an efficient method to send secured images over wireless network. © 2017 Elsevier B.V., All rights reserved.
