Problems solved by technology

Its disadvantages are: professional programmers are required to implement the development of the scheme, the development cycle is long, the protection strength is low in controllability, and the strength is limited by the developer's experience
The disadvantage of shell encryption is that the cracking process of different application software protected by the same shell encryption tool is similar, and the protected content will be reproduced in the memory of the computer

Embodiment Construction

[0029] The present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] figure 1 It is a schematic diagram for protecting program files. refer to figure 1 , where the program file d is a program file that can run normally without any protection. Such a program file is easy to be copied by software pirates and sold at a low price without restriction, causing the owner's economic interests to be greatly affected. infringement. In order to protect the copyright of the program file d from infringement, the protection method of the present invention is used for processing.

[0031] from figure 1 It can be seen that the tool file T contains the encryption algorithm E, the key interface GK filling code F and the protection related code M. Among them, the encryption algorithm E can be 3DES, AES, etc., and is used to encrypt the program file d; the key interface GK can be used to associate with the smart ...

Abstract

The disclosed software copyright protection method comprises: adding protection code into the program file, modifying file entry point information to let first execute the protection code when loading file and execute the program after interactive processing the program file by the code and key. This invention is simple and has strong protection function.

Description

technical field [0001] The invention relates to a software copyright protection method, in particular to a method for realizing software copyright protection by adding software protection related codes on the basis of program files. Background technique [0002] With the development of computer technology, the software industry is also constantly developing, the functions of software are continuously enhanced, and the number of software is also increasing. However, software piracy has been a major problem for many software developers for many years, so many software developers have to In the development process of software products, efforts are devoted to compiling software protection function modules, especially those industry software products with relatively high prices and oriented to specific fields. However, it is not always possible to achieve the expected results by putting energy into the software protection function during the development of a product. After all, t...
