Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0053] A specific method and device for improving the difficulty of cracking Java software, a verification method and a verification device provided in the embodiments of the present application are described below with reference to the accompanying drawings.

[0054] Such as figure 1 As shown, a method for improving the difficulty of cracking Java software provided in the embodiment of the present application includes:

[0055] S101, add an AOP aspect class i...

Abstract

The present invention relates to a method and device for improving the difficulty of cracking Java software, a verification method and a verification device, including adding an AOP section class in the source code of the Java software to obtain the newly added source code of the Java software; compiling the source code And package the compilation result into the first Jar file; perform code obfuscation on the first Jar file and package the obfuscation result into the second Jar file, obtain the first summary information and hard-code the first summary information into the aspect class; again The source code is compiled and the compiled result is packaged into a third Jar file; the third Jar file is code-obfuscated and packaged into a final released Jar file. This application can automatically weave the code of the anti-tampering module into a large number of business processing methods through the compiler, and identify whether someone has tampered with the software copyright protection module after the software is released in multiple places in the Java software. Combined with code obfuscation technology, it will greatly increase the Java The workload and difficulty of software cracking increase the copyright protection of Java software.

Description

technical field [0001] The invention belongs to the technical field of software copyright protection, and in particular relates to a method and device for improving the difficulty of cracking Java software, a verification method and a verification device. Background technique [0002] The binary files compiled by the Java program can be easily decompiled to obtain the source code, and the source code can be reverse engineered, or after the source code is obtained, the software copyright protection part can be modified and then compiled to crack the software. , which poses a challenge to the software copyright protection of Java programs, and a more effective method for protecting Java software is urgently needed. [0003] At present, the software copyright protection modules provided by many software developers often obtain computer fingerprint information based on one or more information such as the unique characteristic code information of the computer, such as the network...
