Who can provide such a registration machine can only be downloaded once and used once!

Let customers download a registration machine (like downloading a ringtone on a mobile phone and downloading it only once after paying), and can only be used once after downloading, that is, after completing registration of their computer, the registration machine is locked at this registration number, and other numbers are also Don't go in.
If the above functions can be realized, it is more convenient to use an electronic registration process with a computer and a registration number, that is, the customer does not need to return the computer serial number, and you give him the registration number.

Just make a mark in the registry or other place when you use it for the first time, and use the check mark next time.

This is the same as judging whether to register or not.

Consistent with the idea upstairs! !!

Let the software connect to the service and make a note of the connection

I guess lz means that the software registration fee is charged when downloading this registration machine, right?

So, let's analyze what features this registration machine needs to have:

1. This registration machine should have the feature of invalid copy. If someone downloaded it once and copied dozens of them for others to run, it would definitely not work. My idea is that at the same time as downloading, the download leaf generates cookies on this machine, and then verify the cookies when running this program, it must be run within a certain period of time to be effective. In order to prevent customers from disabling cookies, the registrar cannot be operated and payment is made in vain. Before charging, the webpage needs to confirm that the customer has not disabled cookies.

2. This registration machine should be bound with computer features. If the customer system has been reinstalled, customers who have already paid should be able to run this registration machine again. Considering that the customer may change the configuration, my idea is that when the registration machine is running, some characteristics of the computer are transmitted to the server, such as the serial number of the hard disk, the serial number of the motherboard, the serial number of the CPU, and the MAC address. The server matches this information with the information in the database. If it matches most of a record, it is considered that the computer has been registered and cookie verification is not required; otherwise, it is considered not registered. If you haven't registered, you need to verify cookies.

3. What if someone has registered on a computer, and then packaged the registered unlocked software and redistributed it? In this case, the software should also verify the operating environment, and the operating environment needs to be re-registered.

4. What if one person upgrades a lot of hardware at once (or simply the computer is completely broken, buy another one)? It can be re-registered with the mobile phone number used for registration. This registration process only charges a small fee. The previous registration records will be deleted and you can re-register with the registration machine.

The friends upstairs basically considered the problems. It seems that it will be more difficult to achieve.
1. The first thing to do is to prevent copying. This barrier is difficult to pass. My idea is that before the user downloads, after the payment operation, the one-time registration machine is bound to the user's computer (such as the user's computer A certain feature), so it is meaningless to copy the registration machine.
2, If you omit the user's computer and the server to hook, but the registration machine only recognizes the serial number of the user's computer hard drive?
3. If the registered software can be repackaged and released, there is a master at this level, the merchant may not be able to do it!
4. If it is a hard drive replacement, as long as it is not installed on another computer, can you search for the hard drive online (can this re-search?), and you can register again, (such as limit 2~3 Replace the hard disk every time, don't you change the hard disk often?)
What is the specific code to realize the above idea? This is what I want, which expert can help
