Alpha Tec : Watermarking : Videomark
heading_3d.gif (3100 bytes)
Overview

bullet_blue.gif (554 bytes)  VideoMark is a software for casting and detecting invisible watermarks on digital video for copyright protection. Watermarks correspond to specific ID-numbers that are called watermark keys. Each copyright owner of digital video uses his/her private key to cast an invisible watermark. This watermark can be detected later by using the VideoMark and the correct watermark key and without resorting to the original product. VideoMark is available in two versions:

bullet_blue.gif (554 bytes)  Full Version

bullet_blue.gif (554 bytes)  Demo Version

Each copy of the full version is characterized by a unique ID number associated with a specific private key used for watermark casting.

For the demo version, watermark casting can be applied by using 100 keys defined in a particular region. Any key can be tested for watermark detection.
Below, you can download an original video sequence without watermark in mpeg format, and its watermarked version in avi format.
