High Security Image Steganography with Modified Arnold cat map
This addresses security for data hiding in images, but it appears incremental as it builds on existing Arnold transform and LSB methods.
The paper tackles secure image steganography by applying a modified Arnold cat map transform twice in different phases with LSB substitution, achieving high security and high data hiding capacity as validated on standard images.
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.
