Get something unique about your computer to create a free trial

Question

I know that there are several ways to create free trials. My algorithm, which I thought was as follows:

• get what identifies the computer on which the application is installed. let's say I decided to get a Windows product identifier, which might look something like this: 00247-OEM-8992485-00078.

• then the hash of this line and say I end the line: ckeer34kijr9f09uswcojskdfjsdk

• then create a file with random letters and numbers that looks like this:

  ksfjksdfjs98w73899wf89u289uf9289frmu2f98um98ry723tyr98re812y89897982433mc98lpokojiaytfwhjdegwdehjhdjwhbdwhdiwhd78ey8378er83r78rhy378wrgthe6766168168

• then in the file that was randomly generated, find the second number (in this case 8) also find the last number (in this case it is 6) now we multiply these numbers and you get 48: then this will be the position at which I start enter the hash string that I got if you remember: ckeer34kijr9f09uswcojskdfjsdk, so the 48 characters of the file are "f", so replace this "f" with the first character of the hash string, which is c. therefore replace f with c. then move two characters to the right to place 50 and put the next character of the hash line, etc.

• I could also encrypt the file and decrypt it to be more secure.

• every time the user opens the program, check this file and see if the algorithm follows it. if it does not match the algorithm, then this is not a full version of the program.

as you can see, I just need to get something unique with respect to the computer. I was thinking about getting a Windows product key, which I think will be unique, but I don't know how to get it. Another thing I was thinking about is getting the mac address. But I do not think that it is effective, because if the user changes this card, the program will not work. Any information that is unique about the computer will help me a lot.

Answer 1

I know that many companies use a MAC address for this. I'm not sure what the pros and cons of this approach exist, but it's worth a look.

I believe that you can use this method to get the MAC address:

/// <summary> /// returns the mac address of the first operation nic found. /// </summary> /// <returns></returns> private string GetMacAddress() { string macAddresses = ""; foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces()) { if (nic.OperationalStatus == OperationalStatus.Up) { macAddresses += nic.GetPhysicalAddress().ToString(); break; } } return macAddresses; } 

This SO question discusses it in detail: A reliable method to get the MAC address of a machine in C #

EDIT

As others have pointed out, the MAC address is not guaranteed to be unique. After doing a bit more research, there are several other options that may work better. Two that stuck out for me:

• Processor serial number
• Hard Disk Volume Serial Number (VSN)

Get processor serial number:

 using System.Management; public string GetProcessorSerial() { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_BaseBoard"); ManagementObjectCollection managementObjects = searcher.Get(); foreach (ManagementObject obj in managementObjects) { if (obj["SerialNumber"] != null) return obj["SerialNumber"].Value.ToString(); } return String.Empty; } 

Get the serial number of the hard drive:

 using System.Management; public string GetHDDSerial() { ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia"); ManagementObjectCollection managementObjects = searcher.Get(); foreach (ManagementObject obj in managementObjects) { if (obj["SerialNumber"] != null) return obj["SerialNumber"].ToString(); } return string.Empty; } 

Answer 2

Everything that has been described can easily be bypassed by a party who wants to spend an hour working on it and writing “hack”.

In addition, the Windows product identifier is not unique. Honestly, for any computer there is no "unique identifier". ( How to get the computer ID? )

I would say keep it simple. Just create a reg key with an encrypted date / time to expire. Read the key every time you start the program to determine when it should expire. Yes, it is as easy to crack as before. However, you will not spend much time developing a complex algorithm that is just as simple.

The fact of the matter is that the Judicial Method is just honest honest people. Those who are going to steal your application will do it independently. So don’t waste your time.

All of the above, I would recommend that you do not even bother. Again, people who want to steal your application will be. People who will pay for it will go ahead and pay. Instead of having a limited test time, change it to a restricted application and give it away. If people want additional features, they can pay and download the unlocked version. At this point, you give them some type of identifier to install in the installer.

Answer 3

If you want something unique about the computer, then you need to put it there.

Create a GUID or other unique value, encrypt it and save it on the computer and on your server.

Answer 4

I used this code in my project. It reads the serial number of the hard drive:

 using System.Management; ... public string ReadHddSerial() { const string drive = "C"; ManagementObject disk = new ManagementObject("Win32_LogicalDisk.DeviceID=\"" + drive + ":\""); if (disk != null) { disk.Get(); return disk["VolumeSerialNumber"].ToString(); } return "other value (random ?)"; } 

You can combine this method and, for example, read the MAC addresses.

Answer 5

Try combining multiple artifacts from a computer instead of one.

Microsoft Windows product activation uses several parmeters, as described here:

There are so many things that a computer can identify. check this!

Now, if I can say that I want to get the serial number of the motherboard, for example, using intelesence, I will do something like:

  var b = new MySystemInfo.Win32_BaseBoard(); b.property = Win32_BaseBoard.Property._SerialNumber; MessageBox.Show("this computer BaseBoard serial number is: " + b.GetInfo); 

also the nice part about this is the visual studio skill:

In this picture, I just showed you the available things that I could get about the Baseboard, but take a look at all that you might want to get:

You guys may not need this to create a free trial, but that's good. I hope you will like it

Answer 7

Thank you very much for your help ... Therefore, based on all your answers, I thought about the following:

so it’s true that there is no specific part about this computer that identifies it. But it’s true that some parts do not change often, for example, information about the motherboard, nic card, etc., Therefore, my new algorithm looks like this:

1) force the user to create an account and save his email and password on my server.

2) get information about the MainBoard user and create a file with the same algorithm that I previously showed.

3) get the MAC address of users, if it has an explicit card, and create another file with the same algorithm as I showed earlier.

3) get the cpu computer id and do the same.

4) another thing may arise that is currently unique in relation to this user, maybe on the hard drive, something like this.

5) when the lauches program checks to see if at least one of the files follows an algorithm. I mean, what are the chances of someone changing their motherboard, blank card, processor, etc ... and if this happens, ask the user to go online to authenticate with the server. In other words, the user can change his nic card, and the program will still be running, because the file for the cpu processor still follows the algorithm.

Answer 8

I cannot add so many characters to my previous questions. add these additional classes to the MySystemInfo namespace that I recently posted:
