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.
