ABSTRACT:
A keyed-build system for controlling the distribution of software. The system and method of the present invention control distribution of software by keying computer-executable programs with device identifications. Each of the computing devices of the keyed-build system contains a device identification that is uniquely associated with and is embedded in the device. A computer-executable program for use in a particular computing device is keyed with the device's unique device identification during the build process of the program. When the computer-executable program is launched on a computing device, the device identification in the program is compared with the device identification embedded in the computing device. If the two device identifications do not match, the computer-executable program is disabled.
