Intelligent Document Scanner
Abstract: AbstractThere is an irresistible trend in the present world for scanning the paper documents and convert it into a digitalized format. Most of these scanning treat the whole document as an entire image. In this scenario, we propose a novel “Intelligent Document Scanner” which automatically segment and classify the contents of the image document including texts, tables and images and store it as a PDF document with three sections that …

Rotation Invariant Copy-Move Image Forgery Detection Using a Method Based on Fuzzy-Zernike Moments
Abstract: AbstractWithout leaving any visual clue, digital images are easy to manipulate due to the availability of countless editing software packages. Any image manipulation can become a forgery. Copymove forgery is a very common method of creating forge images by copying some part of the image and pastes it on the same image. In this paper, we propose a copy-move digital image forgery detection method using Fuzzy-Zernike Moments. The proposed method …

Authentication Scheme using Matrix
Abstract: AbstractThese days, textual passwords are mostly used for authentication. But, these are not much secure because of the problems like brute force attacks, eves dropping, shoulder surfing and guessing. So, there are another authentication schemes to remove these problems, based on session passwords for authentication, and are called color and image authentication schemes. Matrix authentication scheme is based on the session password but with the help of matrix pattern. User …
