Embodiment Construction

[0028] Embodiments and examples of the present invention will be described in detail below with reference to the drawings.

[0029] The scope of applicability of the present invention will become apparent from the detailed description given below. It should be understood, however, that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are given for purposes of illustration only.

[0030] Current trusted timing sources include, but are not limited to, satellite navigation system timing and Internet timing. Satellite navigation systems such as GPS, Beidou, GLONASS, Galileo and other satellite navigation / positioning systems have timing functions, that is, local devices receive satellite time and give time to local devices. Internet time service refers to the time service through time calibration with the time source through the NTP protocol (Network Time Protocol).

Abstract

The invention discloses a software license validity verification method, a software license validity verification system and corresponding computer equipment. The software license validity verification method comprises the steps of: in response to the installation of software, acquiring software installation time from a trusted time service source; determining the sum of the acquired software installation time and effective duration of the software license as expiration time of the software license and recording the expiration time; after the software is successfully installed and used, automatically acquiring current time given by the trusted time service source; comparing the obtained current time with the expiration time of the software license; and determining that the software licenseis valid in response to the fact that the acquired current time not exceeding the expiration time. According to the software license validity verification method and the software license validity verification system, the problem that after the software license is expired, the user tampers the system time privately and continues to illegally use the software license can be avoided, and the effectiveness of the software license is maintained.

Description

technical field [0001] The application relates to the field of electronic digital data processing, in particular to a software license validity verification method, system and corresponding computer equipment. Background technique [0002] A software license (Licence) is a format contract, signed by the software copyright owner and the user, to stipulate and limit the right of the software user to use the software or its source code, as well as the obligations of the copyright owner. [0003] General commercial software has a license authorization, and some authorizations have a time limit. After the time limit, the authorization will become invalid, and the software can no longer be used legally. The existing technology usually determines whether the authorization period expires according to the system time of the device on which the software is installed. The disadvantage is that the user can continue to use the software normally (but illegally) by modifying the system tim...
