PDAC (Parallel Encryption with Digit Arithmetic of Cover Text) Based Text Steganography
Elsevier
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. In this approach one character of cover text hides four character of plaintext so it will increase the performance such as me
ECR(Encryption with Cover Text and Reordering) based Text Steganography

This paper presents ECR(Encryption with Cover Text and Reordering) based text steganography approach which works on simple encryption technique using ExOR Operation of to characters and reorder them which would be more secured and hard to fetch original message from enciphered text. Our encrypted text is reordered using Eight bit random key for hiding our data in a more secure way. Our Eight bit random key will contain four number of zero and four number of one where one bit describes our encrypted text and
