An Image based Steganography Scheme Implying Pseudo-Random Mapping of Text Segments to Logical Region of Cover Image using a New Block Mapping Function and Randomization Technique
Shiladitya Pujari, Sripati Mukhopadhyay · International Journal of Computer Applications · 2012
This paper presented a new scheme of image based Steganography where the secret message is divided or segmented into random number of units holding equal number of characters and the cover image is logically divided into a random number of square blocks.Each logical block of image is used to hide each unit of message in a pseudo-random fashion.These mappings are done by using a new mapping function.
