Survey on Digital Image Forgery Detection

Abstract—Images are the powerful tools for communication. While we may have historically had confidence in the integrity of this imagery, today’s digital technology destroy this trust. The use of digital photography has increased over past few years. With the development of powerful photo editing tools, image manipulation can be done very easily. Composite image is created by the two or more image sources. Naturally all the different images are taken from the different devices and at different world view conditions. Over past five years, the field of digital forensics has emerged to help restore some trust to digital images. While creating a composite image from a number of images, it becomes hard to match the color of one object with reference to the other. This paper analyzes different composite forgery detection methods. Keywords—Digital image forensics, Composite image
