A Steganography Algorithm for Hiding Secret Message inside Image using Random Key

IJERT [ http://bit.ly/2X6F10M ]
"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.

An Efficient Text Steganography using Digit Arithmetic

Elsevier (AETACS2013) [ http://bit.ly/2QnBvwx ]
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.

PDAC(Parallel Encryption with Digit Arithmetic of Cover Text) Based Text Steganography

Elsevier (AETACS2013) [ http://bit.ly/3cvoj3q ]
This paper presents an efficient text steganography approach based on simple mathematical calculation and parallelism. In this approach we are doing simply addition and subtraction with the digits of ascii code of each character of cover text and then this new digits will use to encrypt our plaintext. For enhancing the performance of our algorithm we use parallelism for encryption.
