Task: Tracking down the originator of illegal software copies.

Premium software is delivered to registered customers via the internet. The software is not protected against illegal use, but it should be possible to track down the originator of illegal software copies.

Solution: Individualize the software with MCFACT.

Components of the software, for instance a library, can be built for each customer individually. Specific program code of the library is protected with MCFACT. The protected program code itself is the watermark which is unique for each build.
