Abstract

Digital forensics deal with cyber crime detection from digital multimedia data. In the present day, multimedia data such as images and videos are major sources of evidence in the courts of law worldwide. However, the immense proliferation and easy availability of low-cost or free, user-friendly and powerful image and video processing software, poses as the largest threat to today's digital world as well as the legal industry. This is due to the fact that such software allow efficient image and video editing, manipulation and synthesis, with a few mouse clicks even by a novice user. Such software also enable formation realistic of computer-generated images. In this chapter, we discuss different types of digital image forgeries and state-of-the-art digital forensic techniques to detect them. Through these discussions, we also give an idea of the challenges and open problems in the field of digital forensics.
