Abstract: 
In the past decade, we have seen a remarkable growth in ability to capture and distribute digital videos. But, taking into consideration the availability of too many powerful and user-friendly video editors, the question is how to verify the authenticity of these digital videos. The problem becomes crucial, when it comes to videos used in courts as evidences or journalism. Based on our deep experience in the field of digital image forensics and cooperating with law enforcement authorities, our aim is to develop several highly needed methods for identifying tampering in digital videos as well as ballistic analysis of video signals. Specifically, we will develop methods for video source verification using adopted sensor noise patterns, provide an extensive quantitative experiment analyzing their robustness and detect video tampering using sensor noise and non-consistencies in traces of interpolation. Moreover, we propose a method detecting re-captured videos.
