Abstract

The invention provides a control method and system for a period of validity of software. The method comprises the following steps of: setting an initial date and an expiration date of the software in the software, wherein the period of validity of the software ranges from the initial date to the expiration date; after installing the software in a server and when the server starts the software, starting a built-in clock by the software to record the service life of the software, triggering a guard process to guard a system main process when the software is closed, and starting a timer to record the guard time; updating the service time according to the guard time by the built-in clock of the software, and comparing the updated service time with the period of validity of the software to confirm whether the usage of the software expires.

Description

technical field [0001] The invention belongs to the field of software protection, in particular to a method and system for controlling the valid period of software. Background technique [0002] In commercial software, it is usually necessary to determine the usage time of the software used by the user, so as to charge according to the usage time or provide a free trial period for a certain period of time. However, at present, based on security considerations, users not only allow the software to run on the Internet, but also allow the software to run on an independent local area network. In this way, when a commercial software runs on a closed server, the user can modify the server time and other related system parameters to achieve the purpose of extending the validity period of the commercial software, which will cause losses to the commercial software seller. Contents of the invention [0003] The present invention provides a software validity period control method an...
