Image steganography in high entropy regions using a key & modified LSB for improved security
Sreekutty S Kumar, S. V. Sylish · 2017
In this modern era, the internet has become the most widely used communication channel. The contents of transmission must be of any forms i.e. message texts, voices, images etc. To secure these contents various techniques are used. Steganography is one such technique where the data is hidden from an intruder. This paper makes use of the concept that more information can be hidden in the edge regions when compared to that of smooth regions. The cover image used for embedding the payload or information bits is first altered using a key, which adds to the security of the system. An improved cover image, a novel edge preserving mechanism along with a final control improves the efficiency of the system. The experimental results show the performance of the proposed scheme.
