Embodiment Construction

[0025] figure 1 It is a schematic flow chart of the present invention, such as figure 1 The process flow of the present invention shown comprises the following steps:

[0026] The software developer generates and sends a license information installation package with a license information serial number.

[0027] Step 101, the software developer terminal sets the content of license information.

[0028] In this step, the software developer terminal sets the scope of application of the license information, the target software protection device of the license information, and the license content of the license information.

[0029] Step 102, the software developer calculates and sets the license information serial number of the license information.

[0030] In this step, the software developer calculates the license information serial number of the new license information according to the preset license information serial number transformation rules, and sets the license inform...

Abstract

A method for preventing the repeated release of license information is used for ensuring the one-time validity of the license information. The method realizes the one-time validity of the license information by adding a serial number of the license information in the license information. The serial number of the license information is ordered data, and the size of the serial number of the licenseinformation refers to the sequence of the serial number of the license information in the ordered data. The later of the position of the serial number of the license information is in the ordered data, the bigger the serial number of the license information is. The one-time validity of the license information is realized by saving the installed biggest serial number of the license information in a software protection device and only allowing the license information with the serial number which is bigger than the serial number of the license information saved in the software protection device to be installed.

Description

technical field [0001] This law relates to software protection technology, especially software license control technology, especially a method for preventing duplicate software licenses. Background technique [0002] Functional modules: codes, data, or codes and data extracted from software products by software developers that can or have been placed in software protection devices for external calls. [0003] With the rapid development of economy and technology, software has penetrated into all walks of life as an auxiliary tool. Software products are the crystallization of the wisdom of software designers and software programmers. The survival and development of software developers is the basis for sufficient supply of software products. Therefore, it is of great practical significance to protect the copyright of software products and prevent software products from being pirated. [0004] Among the many strategies that software developers have used to protect software prod...
