Description: 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.
Keywords: Stenography, Text stenography, Security, Secrecy, Privacy.
