Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 shows a flowchart of a method for securely applying software according to an embodiment. It can be understood that the method can be executed by any device, device, platform, or device cluster that has computing and processing capabilities. The method will be described below by using a terminal device (for example, a computer) to execute the method.

Referring to Figure 1, the method includes:

Step 101: When running the executable file used for installation in the software installation package, obtain the unique identification information of the terminal device to install the software.

In step 101, by obtaining the unique identification information of the terminal device to install the software, it is beneficial to determine whether the terminal device is installing the software for the first time in combination with the registration information of the software in subsequent steps.

In some implementations, the unique identification information includes the host name, hard disk serial number and MAC address of the terminal device. Generally speaking, the serial number of the hard disk of the terminal device is unique, therefore, the unique identification information at least includes the serial number of the hard disk. In order to further increase the uniqueness of the terminal device, other hardware parameters of the terminal device (such as host name and MAC address) can also be taken into consideration.

Step 102: Obtain the registration information of the software.

Usually, industrial software generally includes two versions: network version and stand-alone version. In order to adapt to different versions of software, the storage media of software registration information are different. For example, the registration information of the software of the network version can be stored in the authorization center, so as to use the authorization center to centrally manage and control the software of multiple network versions; CD). What needs to be pointed out here is that in the prior art, there is also an anti-piracy method using hardware modules such as dongle U disks. However, this method usually means that one dongle U disk can only install one software in one terminal device. For terminal device installation, you either need to purchase a new dongle USB flash drive, or you need to uninstall the software installed in the original terminal device, and then install the software in the replaced terminal device. It can be seen that this anti-piracy hardware method is not conducive to reducing installation costs.

In the following, the registration information of the online version of the software is stored in the authorization center, and the registration information of the stand-alone version of the software is stored in the USB flash drive.

In some implementation manners, step 102 may include the following two specific situations.

Situation 1. When the version of the software is the online version, execute: encrypt the unique identification information and send it to the external authorization center; after the authorization center passes the verification of the encrypted unique identification information, receive the Software registration information.

In case one, the unique identification information may be encrypted using encryption algorithms such as AES and base64. If the authorization center can decrypt the encrypted unique identification information with the pre-agreed encryption algorithm, it can prove that the unique identification information is legal. Furthermore, in order to prevent the unique identification information from being maliciously tampered with, the terminal device can encrypt the unique identification information according to certain encryption algorithms to obtain a verification value. When the authorization center decrypts the encrypted unique identification information, it will also obtain the corresponding check value, compare the two check values, if they are the same, it means that the verification is passed, and at the same time, the authorization center sends the pre-stored registration information of the software to the terminal device. It can be seen that the above solution can increase the confidentiality of the software registration information during the acquisition process.

Case 2: When the version of the software is a stand-alone version, execute: obtain the encrypted registration information of the software stored in an external storage medium; decrypt the encrypted registration information of the software to obtain the registration information of the software.

In the second case, the registration information of the software can be stored in a USB flash drive, that is, the software provider can provide a bundled sale of the USB flash drive and the software installation package to increase the security applicability of the software. However, this method provided by the present invention can reduce the cost and prevent the problem that the software cannot be recovered due to the system crash compared with the method of using the dongle USB disk in the prior art. The analysis process can be referred to below, and will not be carried out here narrative.

By encrypting the registration information of the software stored in the U disk, it is beneficial to increase the confidentiality of the registration information of the software during the acquisition process. In some implementations, algorithms for encrypting registration information include but are not limited to encryption algorithms such as AES and base64.

It should be noted that the U disk used in the second scenario can be a common U disk, which can reduce the cost compared with the dongle U disk. First of all, it is necessary to repartition the ordinary U disk, for example, through the relevant API interface of the terminal device (such as the DeviceIoControl interface), and then pass in API parameters such as IOCTL_DISK_GET_DRIVE_GEOMETRY, IOCTL_SCSI_PASS_THROUGH, etc., to obtain the size, sector, track, etc. of the U disk information, clear the U disk partition table, and repartition the U disk. Then, write the new setting partition into the U disk to form an encryption area and a common area. The common area can be used normally (the function is the same as that of an ordinary U disk), and the encryption area is used to store the registration information of the software.

In some implementations, in order to ensure that the registration information of the software will not be illegally tampered with, it may be considered to compare the check value generated during the encryption process of the registration information to ensure the integrity of the data.

Specifically, the encrypted registration information of the software includes a first check value generated by encrypting the registration information of the software using a preset encryption algorithm;

In case 2, the encrypted registration information of the software is decrypted to obtain the registration information of the software, including:

decrypting the encrypted registration information of the software by using an encryption algorithm, and generating a second check value;

If the first check value and the second check value are equal, the registration information of the software is obtained.

Step 103: If the registration information does not include the unique identification information, then execute: determine whether the software can be installed on the terminal device according to the registration information; if yes, install the software on the terminal device, and add the unique identification information to the registration information middle.

When installing software on a terminal device, it is necessary to verify whether the software is installed on the terminal device for the first time, so as to improve the installation efficiency of the terminal device. In the embodiment of the present invention, it is judged whether the software is installed on the terminal device for the first time by judging whether the registration information of the software includes the unique identification information of the terminal device. Specifically, if the registration information does not include unique identification information, it proves that the software is installed on the terminal device for the first time; if the registration information includes unique identification information, it proves that the software is not installed on the terminal device for the first time. That is to say, installing the software on the terminal device and adding the unique identification information to the registration information is beneficial to verify whether the software is installed on the terminal device for the first time, so as to improve the installation efficiency of the terminal device.

In some implementations, the registration information includes remaining registration points, and the software will consume a preset number of remaining registration points each time it is installed on a terminal device. In step 103, it is determined whether the software can be installed on the terminal device according to the registration information. On the terminal device, it may specifically include the following steps:

In this embodiment, whether the software can be installed on the terminal device is judged indirectly by using the remaining registration points included in the registration information. For example, the registration information in the U disk corresponding to software A includes 10 remaining registration points (i.e. available registration points), and 5 registration points are needed (or consumed) to install software A, so the U disk can still Perform two installations on different terminal devices; if the remaining registration points in software A are 0 points, you cannot continue to install on different terminal devices. It can be seen that the U disk can not be limited to install one terminal device by setting the number of registration points. The more remaining registration points included in the U disk, it means that the U disk can install software to different devices. The greater the number of terminal devices, the lower the cost of software installation (mainly hardware cost). In some embodiments, the preset number may be 1. That is to say, installing software by using an ordinary U disk is safer, more convenient and flexible than using software, and the installation cost is lower than using hardware (such as dongle U disk).

Further, after the step of adding the unique identification information to the registration information, it further includes:

The result of subtracting the preset quantity from the remaining registration points included in the registration information is used as the new remaining registration points, and the new remaining registration points are added to the registration information.

For example, following the previous example, when the remaining registration points in software A are 10 points, 5 registration points need to be used (or consumed) to install software A. After installing a terminal device (and this terminal device is the first installation) The software), the remaining registration points in software A are 5 points, and then the registration information is updated, that is, the new remaining registration points (that is, 5 points) are added to the registration information.

In this embodiment, as the installation of different terminal devices proceeds, the remaining registration points included in the registration information of the software are correspondingly updated synchronously, so as to ensure the integrity of the data.

Step 104: If the registration information includes unique identification information, then execute: determine whether there is a program file formed after the successful installation of the software package in the terminal device; if yes, skip the installation step; Install the software on your computer and leave the registration information for the software unchanged.

When installing software on a terminal device, if it is determined that the software has already been installed on the terminal device, the registration points of the registration information do not need to be consumed. Among them, "installed" includes two situations where the software already exists in the terminal device, or does not exist (for example, the software is lost due to system flashing) and the registration points of the software have not been recovered.

In the case that the software already exists in the terminal device, that is, there is a program file formed after the successful installation of the software package in the terminal device, at this time, the installation step can be directly skipped to ensure the installation efficiency of the terminal device.

In the case where the software exists on the terminal device (for example, the software is lost due to system flashing) and the registration points of the software have not been recovered, it can prevent the problem that the software usage rights cannot be recovered due to system crashes, that is, in the In this case, the software can be continuously installed on the terminal device that has installed the software without consuming registration points.

It can be seen that in the process shown in Figure 1 above, by obtaining the unique identification information of the terminal device to be installed and the registration information of the software, if the terminal device is installed for the first time, the registration information does not include the unique identification information, and it needs to be registered according to the registration information. Information to determine whether the software can be installed on the terminal device, so that the user does not need to input a registration code or serial code that matches the software, which improves the security applicability of the software; if the terminal device is not installed for the first time, then You can choose to skip the installation or reinstall directly according to whether there is a program file formed after the successful installation of the software package in the terminal device, so that the user does not need to input the registration code or serial code that matches the software, which improves The security applicability of the software.

It can be understood that the safe application of software is not only reflected in the process of installing or registering the software, but also in the process of uninstalling or recycling the software. Among them, please refer to the following for the uninstallation process of the software.

In some embodiments, after step 103 and step 104, the above method further includes the following steps:

When running the executable file used for uninstallation in the software installation package, delete the unique identification information included in the registration information, and increase the number of remaining registration points included in the registration information by a preset number as the new remaining registration points, and Add the new remaining registration points to the registration information.

In this embodiment, the registration points can be reclaimed when the software is uninstalled, and the reclaimed registration points can be used to install on other different terminal devices. It can be used freely by personnel, that is, it can be understood that after the user purchases a USB flash drive that can be installed to a certain number of terminal devices, the limit of the number of terminal devices that can be installed to meet the number of terminal devices can be realized from beginning to end, and will not change.

To sum up, the above technical solution does not need to add other security devices, and the stand-alone version or the network version can be installed according to the needs. Even if the installation process is skipped after being cracked, the installed program lacks the registration information in the U disk and cannot run normally. Therefore, The safety applicability of the software can be further enhanced.

In addition, when the software is uninstalled, the registration points can be recovered for the installation of other terminal devices; and the software exists on the terminal device (for example, the software is lost due to system flashing) and the registration points of the software have not been recovered. Among them, it can prevent the problem that the software usage authority cannot be recovered due to the system crash, and increase the user's satisfaction with the product.

Fig. 2 shows a flow chart of a method for securely applying software according to another embodiment. Referring to Figure 2, the method includes:

Step 201: When running the executable file used for installation in the software installation package, obtain the unique identification information of the terminal device on which the software is to be installed.

Step 202: Obtain the registration information of the software.

Step 203: If the registration information does not include unique identification information, execute: if the remaining registration points included in the registration information are not less than the preset number, install the software on the terminal device, and subtract the preset number of remaining registration points from the registration information. The result after the number is used as the new remaining registration points, and the new remaining registration points and unique identification information are added to the registration information.

Step 204: If the registration information includes unique identification information, then execute: determine whether there is a program file formed after the successful installation of the software package in the terminal device; if yes, skip the installation step; Install the software on your computer and leave the registration information for the software unchanged.

Step 205: When running the executable file used for uninstallation in the software installation package, delete the unique identification information included in the registration information, and increase the number of remaining registration points included in the registration information by a preset number as a new remaining registration points and add the new remaining registration points to the registration information.
