A Robust and Secure Methodology for Network Communications
With the rapid development of a network multimedia
environment, digital data can now be distributed much faster and
easier. To maintain privacy and security cryptographic alone is
not enough. In recent years, steganography has become attractive
vicinity for network communications. In this paper, an attempt is
made to develop a methodology which calculate the variance of
secret message (which the sender wishes to send) and
accordingly create a carrier file. This carrier file can be sent in
any network (secure & unsecure) without giving any doubt in the
attackers mind. The practical implementation of this has been
done on Microsoft platform. Experimental results show the
feasibility of the proposed techniques.
