Copy Move Image Forgery Detection with Exact Match Block Based Technique

Priyanka Arora* and Derminder Singh

[ View:    Abstract ] [ HTML Full Text]

Digital images are a momentous part of today’s digital communication. It is very easy to manipulate digital images for hiding some useful information by image rendering tools such as Adobe Photoshop, Microsoft Paint etc. The common image forgery which is easy to carry out is copy-move in which some part of an image is copied and pasted on another part of the same image to hide the important information. In this paper we propose an algorithm to spot the copy-move forgery based on exact match block based technique. The algorithm works by matching the regions in image that are equivalent by matching the small blocks of size b b. The program is tested for 45 images of mixed image file formats by considering block sizes 2, 4, 6, 8, 10, 12, 14, and 16.? It is observed from the experimental results that the proposed algorithm can detect copy-move image forgery in TIF, BMP and PNG image formats only. Results reveal that as the block size increases, execution time (time taken by CPU to display output) also increases but the number of detected forged images increases till block size 10 and attains saturation thereafter. Consequently block size should be set to 10 for getting good results in terms of less execution time.

E-learning system is designed to aid students build their comprehension towards their respected academic subjects to make their experience in learning more nourishing and engaging. The researchers decided to conduct this study to be au fait the benefits of online education and how the students accept the change this innovation gave. A survey questionnaire was distributed to the enrolled college students of AMA Computer College Year 2018-2019 to make the research more reliable, accurate and at the same time tackle the benefits of the said innovated education system. The said research was a success in defining what helps the students in their education as well as the improvement it can do in terms of catering different subjects and assessing the learners’ competency. The researchers recommend the future researchers to further expand and elaborate the topic in order to enhance the study. To further extend the scope and distribute further information regarding the tackled study.
