However, the local time of the computer can be changed, and the software will be reactivated after being changed to an appropriate time point, and there is a risk of the license being reused
[0003] In addition, although some software will record the usage time of the software in the registry or file system, to a certain extent, it can prevent users from modifying the time to reuse the license, but When the user reinstalls the system after modifying the time and re-registers, the license can still be reused

Embodiment Construction
[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] according to Figure 1-2 Shown, the software License verification method of a kind of anti-tampering time of the present invention is illustrated, comprising the following steps:
[0031] S1. Give the license a unique identifier when generating the software license. When registering the software license, first verify the legality of the time of the license file;
[0032] For non-lifetime authorized licenses, it generally includes the effective time period. When registering the soft...

The invention provides a software license verification method capable of preventing time tampering, which comprises the following steps: S1, endowing a unique identifier to a license when the softwarelicense is generated, and verifying the legality of license file time when the software license is registered; S2, acquiring a hardware unique identification code of the system, and encrypting and storing the hardware unique identification code, the unique identification of the software license and the system time in a license verification file; S3, taking the hardware unique identification codeas a sector logic number, finding a corresponding sector, and writing the content of the license verification file into the sector to obtain a license verification sector; and S4, verifying the legality of the license by adopting a periodic verification mode or a verification mode when software is started, and meanwhile, checking the legality of time in the license verification file and the license verification sector. According to the invention, a user can be prevented from multiplexing the license by modifying the system time, and the user can also be prevented from multiplexing the licenseby reinstalling the operating system.
Description
technical field [0001] The invention relates to the technical field of software, in particular to a software license verification method for tamper-proof time. Background technique [0002] The traditional software license verification method simply compares the local time of the computer with the effective time range of the license authorization, expecting that the software can only be used normally within a specific time range. However, the local time of the computer can be changed, and the software will be reactivated after being changed to an appropriate time point, and there is a risk of the license being reused. [0003] In addition, although some software will record the usage time of the software in the registry or file system, which can prevent users from reusing the license by modifying the time to a certain extent, but when the user reinstalls the system after modifying the time and then re-registers, the license will still remain. can be reused.
