Abstract

The present invention relates to software copyright protecting method, and is especially software copyright protecting method by extracting partial codes from program file to the enciphering device. The compiled program file has its codes decomposed into partial codes running in the enciphering device and the other in the computer, and this makes it possible for the software developer to raise the enciphering safety degree without increasing load in developing software protecting functional module. The software copyright protecting method is superior to traditional shell enciphering method.

Description

technical field

[0001] The invention relates to a software copyright protection method, in particular to a software copyright protection method for extracting part of codes from a compiled program file containing instruction codes to an encryption device. technical background

[0002] Program file: refers to the file containing binary instruction code generated after compilation. The present invention is a technical solution for software copyright protection implemented for program files.

[0003] Data files: mainly refers to those files that do not contain instruction codes, such as pictures, documents, database files, etc.

[0004] The codes mentioned in this article refer only to binary instruction codes unless otherwise specified.

[0005] Source code files: generally in text format, including character strings and identifiers that can be recognized by the corresponding compiler to describe the program flow and calculation rules, and can be converted into program files...
