In this paper, a security model is proposed which imposes the concept of secrecy over

privacy for text messages. In the recent years, we have plenty of security tools which are

developed to protect the transmission of multimedia objects. But approaches for the security

of text messages are comparatively less. The model proposed by us 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.
