As the rise of the digital era, analog data such as text, audio, photo and video are transformed to digital format for wide use and applications. In order to easy use and analysis on computers, analog images are transformed to digital file format by digital encoding techniques. Although digital images are widely used and analyzed on computers, the ease of alteration and duplication over the Internet also causes a serious issue on digital content protection. Digital images are easily altered by using photo editing softwares. These types of softwares include Photoshop, Picasa, Photoscape and online alternatives are Pixlr.com, Paint.net, Photoshop.com. Therefore these tampered images can not be taken for the purpose of any proof. So,detection of these tampered areas in image is a serious challenge for forensic department. This paper shows that digital watermarking methods are of increasing interest and gaining popularity for image tamper detection. Digital watermark is one type of marker which is embedded in the signal such as audio or image data. Digital watermarking is a process of hiding information in the original data for protection of illegal duplication and unauthorized alteration.
