MCFACT has been designed to link program code with a specific security hardware. The security of the MCFACT hardware link is based on a hard mathematical problem. Linking program code with a security hardware is the basis for software copy protection.

Software Copy Protection
A protected software product is comprised of MCFACT protected program code and a security hardware. Without the security hardware the software product is incomplete and the protected application can not be executed because the MCFACT protected program code requires the security hardware to run correctly.

Link to Security Hardware
In general, the MCFACT hardware link can be implemented with any programmable micro controller. The highest level of security is achieved with hardware that has tamper-resistant properties, e.g. a smart-card.

Link to Remote Server
Instead of using a security hardware, the MCFACT hardware link can also be implemented using a DRM system that runs on a remote server.
