Text Steganography: A Novel Approach
Debnath Bhattacharyya, Poulami Das, Samir Kumar Bandyopadhyay, Tai-hoon Kim · 2009
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. 1.
