• The main executable files on a DiscGuard-protected CD-ROM are encrypted.
• A special digital signature is inscribed onto a pressed CD-ROM, and mapped into a software decryption key. The digital signature is not reproducible by either counterfeiting (re-mastering) or disc burning.

When an authentic disc is used, the signature is present, decryption occurs and the application runs. The user is not even aware that the product is protected. When a copy is used, the signature is not present, no decryption occurs and the application does not run. Instead, a message, a limited demo, a link to an e-commerce web site or a presentation is launched. This transforms every illegal copy into a marketing tool and revenue generator.

It can be used virtual for any kind of media:  CD-ROM, CD-R, DVD-ROM & DVD-R

Addressing both problems of illicit mass-reproduction of software or other electronic content (counterfeiting) and copying by a casual user using the low-cost CD recorders available on the market today (disc burning), the Company's innovative solution for CD replication protection is integrated into the laser optics system of CD mastering machines. This technology enables the detection of unauthorized reproduction of the CD itself, without reference or change to the data contained on it.

The unique DiscGuard™ signature is not reproducible by pressed disc counterfeiting nor by CD-R burning. Thus, a pirate who attempts to replicate a DiscGuard™ disc will be able to only copy its content but not the embedded signature.

When the DiscGuard™ verification software detects that the application is being run from a unauthorized copy CD, a demo version of the application or other alternate program can be run at the software developer's choice.
