Video device fingerprinting
All video recorders leave individually identifying clues in the data. The information can be used forensically in many ways, including matching a particular machine to a certain video. The EU-funded 'Digital image and video forensics' (DIVEFOR) project studied the forensic applications of video device fingerprints and of hidden data. The former included device identification and detection of licensing infringement. Research addressed measures to prevent removal or alteration of the digital fingerprint. The set of applications based on hidden video data involved authentication, content integrity verification, copyright protection and detection of covert communications. The four-member consortium ran between mid-2010 and mid-2014. Technical milestones included formulation of the device fingerprint vector, development of forensic applications, and detection of device fingerprint removal and substitution. The team also developed semi-fragile/fragile digital watermarking, robust digital watermarking, and steganography and steganalysis. The work yielded a total of 24 conference papers and 10 journal papers. The project applied for four patents, three of which were pending as of the project's conclusion. Additional dissemination work included a set of 4 technical reports, and a series of 20 lectures and demonstrations. The DIVEFOR project resulted in development of applications of digital fingerprint analysis technologies for video. The consortium also secured a number of future collaborations and funding opportunities.
