Abstract-Watermarking is done in digital images for authentication and to restrict its unauthorized usages. Watermarking is sometimes invisible and can be extracted only by authenticated party. Encrypt a text or information by publicprivate key from two fuzzy matrix and embed it in image as watermark. In this paper we proposed two fuzzy compositions Product-Mod-Minus, and Compliment-Product-Minus. Embedded watermark using Fuzzy Rough set created from fuzzy matrix compositions.

Abstract-Watermark is used to protect copyright and to authenticate images. In digital media, today's world images are in electronic form available in the internet. For its protection and authentication invisible watermarking in encrypted form are used. In this paper encryption is done using fuzzy ComplimentMax-Product matrix and then encrypted watermark is embedded in the digital media at desired places using fuzzy rule. The Region of Interest (ROI) is decided with fuzzification. Then, watermark is inserted at the respective positions in the image. Robustness of watermark is judged for ROI. This method of watermarking is done on all image file formats and it is resistant for geometric, noise and compression attack.

Abstract-In this paper we will discuss teaching Software Engineering by using classroom teaching and web-based learning. The teaching assignments, notes , slides are also shared in a website while assessment is done one-to-one in viva or test conducted on the learning material. We are using Information and Communication Technology ICT for teaching. Software Engineering courseware are taught in
