Vaibhav Joshi, PhD Scholar awarded best paper in IEEE International Conference on Computing analytics and Security Trends 2016 (CAST - 2016) at College of Engineering Pune (COEP) during 19th December to 21st December, 2016. This paper Introduces a novel and invertible fuzzy based transform which randomize the watermark inside the image. The beauty of the proposed transform is, while randomizing the watermark it does not affect the visual quality of a cover image rather increase the contrast of a cover image. For application of the transform two things are required 1) Modes of an image histogram which introduce image dependency and 2) user define enhancement factor which makes transform more robust against brute force attack.
