摘要：
A computer-based system is provided for preventing unauthorized duplication of a particular software program among a plurality of active software programs executed on a computer. The system receives an indication that the computer is executing the particular software program, and then monitors operation of the computer to determine which of the plurality of the active software programs is being currently executed. When the system determines through the monitoring that the particular software program is not the currently executed software program, it disables execution of the particular software program.
