Using LED Backlight Display Technology to Provide Passive Forensic Marking for High Value Content
Michael A. Sterling · 2009
One of most effective and least technologically challenging ways to pirate content is to point a camcorder at a display screen. As compact and inexpensive HD solid state memory camcorders are becoming readily available, this presents a threat to those content holders attempting to protect high value content throughout the production and post-production process. — Forensic marking techniques are not new and watermarking technology exists to provide an audit trail for digital exhibition but can new technologies in home displays be leveraged to provide an effective system to protect content in post production environments? — We examine several ways in which this can be implemented and discuss the potential benefits of integrating a passive forensic marking system as part of a display device.
