Secure and Imperceptible Intelligence Message Sharing Scheme

Abstract

With the advancement of the computer technology and networking, tons of secret information is being transmitted on the Internet. However secret message are at high risk of stealing because these messages seek attention while they are being transmitted. Therefore achieving safe exchange of secret message is an important field of research. Though symmetric key cryptographic methods offer quite high level of security but they require costly hardware to implement these methods. Stenography is a communication method which hide secret message in the cover to protect it from the potential hacker. The safest method to prevent secret message from leaking to first encrypt it and then hide this message in the cover We propose a Secure Intelligence Sharing Scheme to integrate with high hiding capacity and imperceptibility. The proposed scheme uses AES as cryptographic solution and hash type one-way function to store metadata about cover and secret message. The proposed scheme uses JPEG compression technique to control size of the transmitted message. Our experiment is performed using variety of cover data and secret messages.
