Digital videos play an important role in court rooms, in news, defense and for security purpose to ensure their authenticity and integrity is a important task and also a challenge. On the other hand due to advancement of technology and availability of various editing software tools has made the digital video tampering possible allowing it to modify, edit and alter easily, the digital forensics demands effective research in this field to find different techniques to detect the video forgeries. The various techniques are proposed by the researchers for video tampering detection. But passive techniques are based on detecting the forgeries without the need of pre embedded information .This review paper focuses on various passive techniques which are used to detect forgeries in videos.

The image forgery is practiced in most of the fields such as manipulation of important government documents, wills, financial deeds and educational certificates etc. When the forged images are produced as a proof in a court room that might derive wrong decisions due to illegitimate. Hence checking the genuineness and authenticity of images is one of the most important and active research areas in digital image forensics. In this survey paper we attempt to provide an overview of different approaches for detecting image splicing forgeries.

On the other hand, the availability of free advanced mobile applications and audio editing software like Adobe, Audition CC, etc. enabling people to edit easily the meaningful content of audio recordings data for getting benefit from e-services or producing it in a courtroom for the purpose digital proof. Perhaps, most of the people do it for fun as well as the strong intention of hiding reality present. Moreover, the audio recording captured in a real-life today does not contain digital watermarking and signature content for authentication because of expensive procedure. Therefore, in recent years the researches focused more on developi...
