Abstract

Steganograhy sends message by concealing it so that intruder can't detect the presence of message. It is an art of hiding information in digital media. It ensures that communication between two parties remain secure. Cryptography is another approach used to hide data. After cryptography, steganography came in existence. Steganography and cryptography both are using for the secure the communication. But their way of working is different. Cryptography encodes the message but steganography hides the presence of the message. This modern era need secure communication. For this various security aspects or various techniques are there. There are two types of the steganography one is spatial and the other is frequency domain. This method belongs to spatial domain. In this method image metrix with modulus approach is used to hide data..6*6 image matrix with modulus of 3 is use. Window size is select according to remainder. New approach of modulus method is introducing in this paper. In this paper steganography with cryptography is combine. In this R.S.A. algorithm and modulus approach is combining and trying to make a secure communication.
