High Security Image Steganography with Modified Arnold cat map

TL;DR

This paper introduces a secure image steganography method using spatial domain LSB substitution combined with a modified Arnold transform applied twice, enhancing security and data hiding capacity.

Contribution

It proposes a novel combination of LSB substitution and a modified Arnold transform for improved security in image steganography.

Findings

Method is highly secure against standard attacks.

Provides high data hiding capacity.

Validated on standard images with positive results.

Abstract

Information security is concerned with maintaining the secrecy, reliability and accessibility of data. The main objective of information security is to protect information and information system from unauthorized access, revelation, disruption, alteration, annihilation and use. This paper uses spatial domain LSB substitution method for information embedding and modified forms of Arnold transform are applied twice in two different phases to ensure security. The system is tested and validated against a series of standard images and the results show that the method is highly secure and provides high data hiding capacity.
