Abstract

The invention discloses a file protection method and device, wherein the method includes: encrypting each resource file to obtain each encrypted first resource file; packing the executable file to obtain the packed executable file; The shell of the packed executable file is used to hijack the operation function of the resource file, so as to determine the target first resource from each of the first resource files when the operation function of the resource file is called file, to verify the legality of the target first resource file, and to decrypt the target first resource file when the target first resource file is verified to be legal. The present invention can effectively protect the resource files by encrypting the resource files of the executable files, solves the problem of the resource files being stolen because the resource files are directly stored in the disk, improves the security of the resource files, and further improves the security of the resource files. Executable file security.

Description

A file protection method and device technical field [0001] The present invention relates to the field of software protection, in particular to a software protection method and device. Background technique [0002] There are more and more industries in which the Unity3D engine is applied, such as games, urban planning, entertainment, arts and education, military With aerospace industry, interior design, real estate development, industrial simulation, in cultural relics, Web3d / product / still life display, geography, etc. The industry is using it. [0003] When the Unity3D program runs, it needs to use a lot of other resource files, such as text, pictures, sounds, video frequency etc. The existing program packing method only encrypts the executable program and does not process the resource file. The resource file of program can not be protected using above-mentioned packing method, and these resource files can directly store In the disk, it will face the risk of being m...
