Improvement of security in cloud systems based on steganography

In recent years, many cloud computing systems have been developed over the world. However, since there are many malicious people who want to access secret and personal information stored in cloud servers, information security is still a serious problem to solve. To conceal and protect secret and personal information, in this paper we propose and develop a system that can encrypt secret message and embed it into an image file by using a new morphing based steganograph technique. Even if the malicious people may steal the image containing the secret information, they cannot read the secret information because this is almost impossible without the stego key. Consequently, we expect improvement of security in cloud systems by using our method.
