"Steganography” is a Greek origin word which means “hiding writing”. The steganography word is classified into two parts: Steganos means “secret or covered”(where you want to hide the secret messages) and graphic means “writing”(Text). This paper introduces a new approach for least significant Bit (LSB) based on image steganography that enhances the existing LSB substitution techniques to improve the security of hidden information.

This paper presents text steganography approach based on mathematical calculation and rearrangement of text. In this approach we are doing simple mathematical calculation with the digits of ascii code of each character just by using simple addition and subtraction which is very fast.
