Method and apparatus for detecting tampering with software operation time

Abstract

The invention, which relates to the technical field of information, discloses a method and apparatus for detecting tampering with software operation time. When someone tampers with software operation time, the tampering can be found timely and thus correlated operation for limiting the software operation is carried out, thereby guaranteeing safety and reliability of software copyright protection. The method comprises: reference time and current time of software operation are obtained, wherein the reference time of the software operation is historical time of the software operation; whether the current time exceeds the reference time is determined; and if not, tampering of the time of software operation occurs; and if so, tampering of the software operation time is not done. The method and apparatus are mainly applied to the control process of the software operation.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for detecting tampering of software running time. Background technique [0002] With the development of computer technology, the software industry is also developing and has penetrated into all walks of life. In the process of software use, how to implement copyright protection and prevent software from being stolen is of great significance. In the field of software copyright protection, time-limited control methods are usually used to protect software copyrights. This time-limited control method allows software to be used only before a certain set date, such as software regular trials, leases, and regular use licenses. Way. In order to monitor the software running time, it is necessary to obtain the real-time running time of the software so as to monitor the service life of the software. [0003] At present, the way to obtain the real-time running tim...

Problems solved by technology

[0004] Although accurate timekeeping can be achieved by attaching a clock chip and battery, there are still problems: when crackers discharge the clock chip or send commands through the signal pins of the chip to change the timing information inside the chip, they can obtain information beyond the software. license for use

Faced with this kind of problem, although the method of sealing the pins of the clock chip with glue can prevent the tampering of the internal clock information of the clock chip to a large extent, the glue on the pins of the clock chip is easy to be damaged. After being stripped, the cracker can directly modify the internal information of the clock chip through the pin leads, and obtain the authorization to use the software beyond the service life. In this case, there is no relevant detection method to detect that the running time of the software has been tampered with, resulting in The security and reliability of software copyright protection are low
