A Multi Layer Security Model for Text Messages
2009
Of late in the field of Information Security, we have plenty of security tools which are made to protect the transmission of multimedia objects. But approaches for the security of text messages are comparatively less. In this paper, a security model is proposed which imposes the concept of secrecy over privacy for text messages. This model combines cryptography, steganography (taken as security layers) and along with that an extra layer of security has been imposed in between them. This newly introduced extra layer of security changes the format of normal encrypted message and the security layer followed by it embeds the encrypted message behind a multimedia cover object.
