Video watermarking. A video watermark is an indelible pattern embedded in video content that is imperceptible to the eye. By embedding a unique watermark into video material at the time of production or broadcasting, content owners can identify copies of their material and even the source of these copies, and whether they are legal or not. Watermarking is ideal for, among others, protection of intellectual property rights.

Philips' video watermarking technology has been used successfully for identifying the source of illegal copies of the 2003, 2004 and 2005 Academy Award Screeners.

Audio watermarking. Similar to its video counterpart, digital audio watermarking is a technology to hide information in an audio file without the information being audible to the listener, and without affecting in any way the audio quality of the original file. Its main use is for protection of intellectual property rights, especially protection against online music piracy. Other uses for watermarking technology include embedding auxiliary information or meta-data related to a particular song, e.g., lyrics, singer and other album information.

Video fingerprinting. Next to its leading watermarking technologies, Philips Research has also successfully developed fingerprinting technology. An essential difference compared with digital watermarking is that fingerprinting changes none of the original content. Video fingerprinting provides a digital ‘fingerprint’ of a video file by deriving unique features that can be used to identify the video content by comparing it with reference fingerprints stored in a central database. Some major potential applications of video fingerprinting are video sharing, broadcast monitoring and various triggering applications.
