Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The process of the first embodiment of a method for software deadline verification in the present invention, see figure 2 , the method includes:

[0027] 101: When starting the software, obtain the time when the software is used for the first time, the time when the software is used last time, and the current time, the time when the software is used for the first time and the time when the software is used last and written to the registry the last time said software was launched.

[0028] The time when the software is used for the first time and the time when the software is used last time are recorded in the registry, and when the software is started, the time when the software is used for the first time and the time when the...

Abstract

The invention discloses a method and a device for verifying a software deadline, belonging to the field of software encryption. The method includes: when starting the software, acquiring the time when the software is used for the first time, the time when the software is used last time and the current time, the time when the software is used for the first time and the time when the software is used last time are respectively Write into the registry when the software is started for the first time and last time; judge whether the time when the software is used for the first time is earlier than the time when the software was used last time, and whether the time when the software is used last time is earlier than the current time ; if yes, run said software; if no, prompt user to register. Through the method and device for verifying the software time limit, the present invention realizes the effective verification of the software time limit, and solves the problem that the user modifies the system time by himself in order to prolong the software use time.

Description

technical field [0001] The invention relates to the field of software encryption, in particular to a method and device for verifying a software expiration date. Background technique [0002] With the development of the information society, how to protect one's own software copyright has always troubled every programmer. In various software development and software intellectual property fields, it is quite necessary to use flexible, convenient and economical software registration methods, which not only have a great effect on the protection of software copyrights but also reduce costs and deserve benefits for enterprises. recycling has practical significance. [0003] Such as figure 1 As shown, the process of realizing the registration function is described. After the program is started, registration verification and term verification will be performed. When the output result of registration verification is false, term verification will be performed. According to the resul...
