A New Steganographic Technique Matching the Secret Message and Cover image Binary Value

TL;DR

This paper introduces a steganographic method that encodes secret messages by matching message bits with cover image pixel positions without altering the image, enhancing secrecy through position files and secret keys.

Contribution

It presents a novel steganography technique that encodes messages using pixel position files, avoiding modifications to the cover image for increased security.

Findings

No change to cover image pixels

Secure message retrieval using position files and secret keys

Effective hiding of secret messages without visual distortion

Abstract

Steganography involves hiding a secret message or image inside another cover image. Changes are made in the cover image without affecting visual quality of the image. In contrast to cryptography, Steganography provides complete secrecy of the communication. Security of very sensitive data can be enhanced by combining cryptography and steganography. A new technique that uses the concept of Steganography to obtain the position values from an image is suggested. This paper proposes a new method where no change is made to the cover image, only the pixel position LSB (Least Significant Bit) values that match with the secret message bit values are noted in a separate position file. At the sending end the position file along with the cover image is sent. At the receiving end the position file is opened only with a secret key. The bit positions are taken from the position file and the LSB values from the positions are combined to get ASCII values and then form characters of the secret message
