Random Image Steganography using Pixel Indicator to Enhance Hiding Capacity

M. Padmaa and Y. Venkataramani
Steganography presents us with a secure means of data transfer which protects confidential information from unauthorized change. Putting it simple, it is a boon to prevent the unauthorized access or misuse of secret information. There are a lot of techniques (both spatial and transform domain) in Steganography. The question of “Which technique is the best” can only be answered hypothetically. Every steganographic technique is unique in its own way and produces desired result, that is, protection of information. The technique proposed in this study sheds light on capacity of embedding and high quality visual while being immune to steg analysis attack. Complexity is driven by means of stego key and LSB substitution.
