SYSTEMS AND METHODS FOR SELECTIVELY CONTROLLING AND RECORDING EFFECTIVE USE OF PROGRAMMES SUCH AS SOFTWARE PACKAGES ON COMPUTER STATIONS

摘要

the system detects an instruction to launch a program, verifies in memory the remaining usage time allowed, and allows launching of the program if sufficient time remains. During execution of the program the time counter is progressively decremented. The user's computer (PC) is connected through a network (RE) to a server (SV) which loads the time value to local memory after receipt of payment.
