This paper proposes a hybrid approach to enhanced data security using special matrices in conjunction with Steganography. The special matrices are used for mapping the actual characters to numbers which are actually pointers to the location of the characters in the matrices. The generated numbers corresponding to each character of the message are embedded in the image pixels at the least significant bit position prior to transmission. The change of LSB values of the image pixels do not distort the image significantly, allowing for undetected transmission of any message to its intended receiver.
