At forensic laboratories, cases are submitted for forensic investigation of videotapes and recorders. The video investigation is often requested by the court for different types of crime, like robberies and homicides. For these investigations, most laboratories use a computer to digitize the images uncompressed in such that they try to minimize the ...

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 ...

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 ...

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.

Forensic Analysis of Binary Structures of Video Files
2021 IEEE 5th International Conference on Cryptography, Security and Privacy (CSP), 2021As technology advances, multimedia files such as videos are susceptible to manipulation. This has led to serious concerns that images and videos are not trustworthy evidence as the files can be manipulated easily. As a result, forensic analysis of electronic multimedia files plays an important role in verifying the authenticity of video files.

Video authentication in digital forensic
2015 International Conference on Futuristic Trends on Computational Analysis and Knowledge Management (ABLAZE), 2015The large amount of video content is being transmitted over internet and other channels. With the help of existing multimedia editing tools one can easily change the content of data which lead to lose the authenticity of the information. Thus, it becomes necessary to develop different methods by which the authenticity of the videos can be confirmed. In

Forensic uses of infrared video
Proceedings 1992 International Carnahan Conference on Security Technology: Crime Countermeasures, 2003A comprehensive investigation of the commercial applicability of infrared technology has been conducted. While the main focus of these efforts has been evaluation of technology applicable to an infrared facial identification system, the availability of imaging and image processing equipment has made it possible to assess the use of infrared systems and
