Proceedings of the 2nd ACM workshop on Multimedia in forensics, security and intelligence, 2010
Identifying videos on seized hard drives and other storage devices is a very tedious and time consuming task for forensic investigators. In particular, the vast amount of available material on the Internet and the large storage capacities of today's hard drives have become a strong headache for them.

Forensics and counter anti-forensics of video inter-frame forgery
Multimedia Tools and Applications, 2015Among different types of video manipulations, video inter-frame forgery is a powerful and common tampering operation. Several forensic and anti-forensic techniques have been proposed to deal with this challenge. In this paper, we first improve an existing video frame deletion detection algorithm.

Multimedia content is more accessible than ever before due to a variety of factors including more advanced compression techniques, higher throughput channels, and an increase in media sharing hardware and software. The ease with which people can send and receive media is associated with an increase in the amount of false or misleading media being ...

The PRNU Algorithm of Video Forensics
Digital Forensics (4n6) Journal, 2020The A video sequence provides more proof of an occurring event than a photo or a group of photos. Hence it is important to identify the source of the video. In this paper, we explore how the Photo Response Non-Uniformity (PRNU) noise is useful for the detection of source cameras- Metadata of a Camera.

Image and video fingerprinting: forensic applications
SPIE Proceedings, 2009Fighting movie piracy often requires automatic content identification. The most common technique to achieve this uses watermarking, but not all copyrighted content is watermarked. Video fingerprinting is an efficient alternative solution to identify content, to manage multimedia files in UGC sites or P2P networks and to register pirated copies with ...

Video forensics based on expression dynamics
2014 IEEE International Workshop on Information Forensics and Security (WIFS), 2014Digital graphics tools are nowadays capable of rendering highly photorealistic imagery, which easily puzzle our perception of reality. This poses serious ethical and legal issues, which in turn create the need for further technologies able to ensure the trustworthiness of digital media as a true representation of reality, especially when depicting ...

Median Filtering Forensics in Compressed Video
IEEE Signal Processing Letters, 2019Median filtering has received extensive attention from forensics analyzers, as a common content-preserving, smoothing, and denoising manipulation. We propose a detection scheme for median filtering of video sequences in compressed domain based on the singular value decomposition of the process matrix , which approximates the median filtering ...
