Embodiment Construction

[0016] A first embodiment of the present invention is proposed for implementing protection of executable files in a flash disk.

[0017] This embodiment is based on the WINDOWS operating system and the FAT file system. The FAT file system has a chain structure, and each file has a linked list, which records the storage addresses of all fragments of the file, and organizes multiple file fragments stored in the memory into a complete file. The read operation of the file is based on the linked list of each file, and according to the storage address of the file segment in the linked list, the corresponding file segment is read out from the memory. The read operation on the file includes operations such as reading, copying, or running the file.

[0018] When the information in the file link list is destroyed, the operating system cannot read all the file fragments, thus making the operating system unable to restore the file correctly, and the operating system will report an error ...

Abstract

The invention provides a program file protection method used for a storage device. At least one protection address field is arranged in a program file. The method also comprises the following steps: (1) reading the program file via the storage device to check at least one protection address field; and (2) reading the program file content or canceling the reading operation via the storage device according to the check result. The invention also provides a program file protection device. According to the program file protection method and the protection device provided by the invention, anti-copy protection of the program file is achieved without influencing the normal operation of the program film. The method is safe, reliable, simple and easy to be extended.

Description

technical field [0001] The invention relates to the field of electrical digital data processing, in particular to a program file protection method for a storage device. Background technique [0002] At present, many software providers are troubled by piracy, and there is a need to prevent copying of program files that can be executed by software programs. They hope that program files can be stored in storage devices such as flash drives, and programs can run in storage devices. Unable to copy it out. But in theory, the program must be able to read the content of the program to run, and can read the content must be able to copy. Therefore, this requirement has not been realized. Contents of the invention [0003] The purpose of the present invention is to provide a program file protection method and a protection device, which can realize copy prevention protection for the program file without affecting the normal operation of the program file. [0004] A program file pro...
