Copyright protection method and equipment based on Linux operating system

Abstract

The invention relates to a copyright protection method and equipment based on a Linux operating system. The method comprises the following steps: powering up and starting copyright protection equipment; decompressing a mirror image compressed file of the Linux operating system, loading the mirror image compressed file into a memory, and guiding to start a kernel; calling a system process program,starting a system service and entering a system initialization stage; starting a copyright protection application program, and enabling the copyright protection application program to communicate withthe security chip; enabling the copyright protection application program to detect the characteristic value transmitted by the security chip in a polling manner; if the copyright protection application program does not detect the corresponding characteristic value in the preset time period, feeding the characteristic value back to the system process program and ending the operation of the Linux operating system; even if other people copy the mirror image file of the Linux operating system, it is avoided that the Linux operating system cannot be normally started on other equipment due to the fact that the corresponding characteristic value cannot be detected in a polling mode, and therefore the Linux operating system is effectively prevented from being copied at will, and the copyright ofthe Linux operating system is protected.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a copyright protection method and equipment based on a Linux operating system. Background technique [0002] The so-called embedded is to realize the maintenance-free version with specific functions. According to the current situation, the Linux operating system replaces the Windows desktop system. From a technical point of view, it is not suitable for a comprehensive replacement. The reason is that, firstly, graphics and image processing and graphics card 3D acceleration are obvious shortcomings of the Linux operating system, and there will be no changes in the short term; , so it is difficult to achieve a comprehensive replacement. However, in specific fields, such as daily office work, using WPS Office can meet the daily work requirements, while the Linux operating system is fully capable; another example is some professional systems: POS cash registers, cash m...

AI Technical Summary

Problems solved by technology

[0004] 1. Make an image that runs on a specific hardware. If you can copy it without restriction, it may fail to replace the untested hardware platform, which will increase the difficulty of management and reduce the availability of the system.

[0005] 2. For a specific embedded application, it may involve certain security requirements. If it can be copied and run at will, it will reduce the security of the system

[0006] 3. The interests of developers cannot be guaranteed, because developing and customizing a specific Linux operating system will consume a lot of manpower and material resources, and the investment cost is high. It is only possible to promote the continuous upgrading and improvement of the Linux operating system with the guarantee of commercial returns. Copying will lead to a lot of low-price competition and seriously damage the interests of developers
