Embodiment Construction

[0026] Please check figure 1 , which is a schematic flow chart of an anti-piracy method in a preferred embodiment of the present invention. The anti-piracy method, which includes:

[0027] Step S100, the step of making a fingerprint, which is executed when installing the software. Generally, the software is installed by a designated user, such as installed by an operator. The step of making a fingerprint includes:

[0028] Step S110, read the feature code MAC of the hardware device from the MAC address of the network card, the MAC is inserted when the hardware device leaves the factory, and has unchangeable and unique characteristics;

[0029] Step S121, using the feature code MAC as the plaintext of the encryption algorithm, and the encryption algorithm calculates a calculation data;

[0030] Step S122, compressing the calculation data to obtain and save the cryptographic fingerprint, the cryptographic fingerprint data can be compressed into a single byte;

[0031] Step S1...

Abstract

The invention discloses a piracy preventing method of a system, comprising a step S100 of a fingerprint manufacturing step which is executed when software is installed, and a step S200 of a fingerprint verification step which is executed when the software is executed. The fingerprint manufacturing step comprises a step S110 of reading a feature code MAC built-in by hardware equipment and a step S120 of calculating a storage password fingerprint according to the feature code MAC of the hardware equipment and storing the storage password fingerprint on the hardware equipment. The fingerprint verification step comprises a step S210 of reading the feature code MAC built-in by the hardware equipment and the storage password fingerprint, a step S220 of calculating a verification password fingerprint according to the feature code MAC of the hardware equipment, and a step S230 of judging whether the verification password fingerprint and the storage password fingerprint are equal or not, wherein, the calculation method is the same as that in the fingerprint manufacturing step; if the verification password fingerprint and the storage password fingerprint are equal, the software is continuously executed; and if the verification password fingerprint and the storage password fingerprint are not equal, the software is stopped executing. Because the piracy preventing method judges whether a rights exists or not before the software is executed, a condition that the software is embezzled after the software is copied is effectively avoided, and the piracy preventing function is powerful.

Description

Technical field [0001] The invention relates to a system anti-piracy method. Background technique [0002] At present, embedded software is usually installed on a common storage device, such as a flash disk. Because this type of storage device is versatile, and embedded hardware systems are becoming more and more common, such as systems using X86 and ARM, it will cause the content stored in the storage device to be directly copied to another same storage device. And applied to other hardware systems. In order to prevent the system from being pirated, many solutions have been proposed, mainly including the following two. [0003] The first is to use the network confirmation method. When installing the software, you need to obtain the registration number through the network, and you can only register after obtaining the registration number. This method has the following deficiencies: 1. Because the existing anti-piracy method only judges whether it is authorized to install ...
