VEIL forensic tracking involves the use of imperceptible VEIL marks embedded into content by content owners using a real-time process. These marks allow tracking of the content through the distribution path and into consumer grade playback devices. When a piece of pirated content is discovered, the marks can be recovered and thereby identify the original location that created the leak. This is a low-cost solution that allows content owners the ability to track where their content is delivered and help close possible leaks.
