Steganography based on image morphing
Qiangfu Zhao, Tosiyasu L. Kunii · 2013
Nowadays, large scale data-centers have been built around the world, and cloud computing is becoming more and more popular. With the help of cloud computing, users can access their data and obtain different services anywhere and anytime. However, many people and companies still hesitate to use cloud based services because of the information security problem. If the problem cannot be solved properly, the "clouds" may become a threat to the whole world. Although cryptography is an important technology for solving the problem, it also reveals the existence of secret information and may attract pin-point attacks. In this study, we propose a new type of steganography, in which secret is embedded as hidden information into a virtual but natural image synthesized through image morphing. The basic idea is to make the existence and the meaning of the information unaware, and to make it extremely difficult for unauthorized persons and groups to read or even to find the information. Initial analyses show that the proposed technology is secure, and can be a very promising technique for protecting secret information in cloud computing environments.
