From following the logical path System Hardware Processor Serial Number, I'm expecting to recieve the Processor's SN. Instead, I get the BIOS' SN. This gets worse when I read the source code, and I find that this value is kept in memory as 'cpuSerialNumber'. Public abstract class SerialPort extends CommPort. An RS-232 serial communications port. SerialPort describes the low-level interface to a serial communications port made available by the underlying system. SerialPort defines the minimum required functionality for serial communications ports. Author: Jagane Sundar See Also.

Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. This reference will take you through simple and practical approaches while learning Java Programming language.

Why to Learn java Programming?

Java is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning Java Programming:

  • Object Oriented − In Java, everything is an Object. Java can be easily extended since it is based on the Object model.

  • Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.

  • Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master.

  • Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.

  • Architecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.

  • Portable − Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.

  • Robust − Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.

Just to give you a little excitement about Java programming, I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link.

Applications of Java Programming

The latest release of the Java Standard Edition is Java SE 8. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.

The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere.

  • Multithreaded − With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly.

  • Interpreted − Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light-weight process.

  • High Performance − With the use of Just-In-Time compilers, Java enables high performance.

  • Distributed − Java is designed for the distributed environment of the internet.

  • Dynamic − Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time.

I'd like to get an id unique to a computer with Java, on Windows, MacOS and, if possible, Linux. It could be a disk UUID, motherboard S/N...

Runtime.getRuntime().exec can be used (it is not an applet).

Ideas?

It is common to use the MAC address is associated with the network card.

The address is available in Java 6 through through the following API:

I haven't used it in Java, but for other network identification applications it has been helpful.

The problem with MAC address is that there can be many network adapters connected to the computer. Most of the newest ones have two by default (wi-fi + cable). In such situation one would have to know which adapter's MAC address should be used. I tested MAC solution on my system, but I have 4 adapters (cable, WiFi, TAP adapter for Virtual Box and one for Bluetooth) and I was not able to decide which MAC I should take... If one would decide to use adapter which is currently in use (has addresses assigned) then new problem appears since someone can take his/her laptop and switch from cable adapter to wi-fi. With such condition MAC stored when laptop was connected through cable will now be invalid.

For example those are adapters I found in my system:

Code I've used to list them:

From the options listen on this page, the most acceptable for me, and the one I've used in my solution is the one by @Ozhan Duz, the other one, similar to @finnw answer where he used JACOB, and worth mentioning is com4j - sample which makes use of WMI is available here:

This will print some computer information together with computer Serial Number. Please note that all classes required by this example has to be generated by maven-com4j-plugin. Example configuration for maven-com4j-plugin:

Above's configuration will tell plugin to generate classes in target/generated-sources/com4j directory in the project folder.

For those who would like to see ready-to-use solution, I'm including links to the three classes I wrote to get machine SN on Windows, Linux and Mac OS:

For instance, you could use something like the following code to identify a machine uniquely:

Java Serial Number

Output for my machine:

Your output will be different since at least the processor serial number will differ.

What do you want to do with this unique ID? Maybe you can do what you want without this ID.

The MAC address maybe is one option but this is not an trusted unique ID because the user can change the MAC address of a computer.

To get the motherboard or processor ID check on this link.

On Windows only, you can get the motherboard ID using WMI, through a COM bridge such as JACOB.

Example:

And if you choose to use the MAC address to identify the machine, you can use WMI to determine whether an interface is connected via USB (if you want to exclude USB adapters.)

It's also possible to get a hard drive ID via WMI but this is unreliable.

Be careful when using the MAC address as an identifier. I've experienced several gotchas:

  1. On OS X, ethernet ports that are not active/up do not show up in the NetworkInterface.getNetworkInterfaces() Enumeration.
  2. It's insanely easy to change a MAC address on cards if you've got appropriate OS privileges.
  3. Java has a habit of not correctly identifying 'virtual' interfaces. Even using the NetworkInterface.isVirtual() won't always tell you the truth.

Even with the above issues, I still think it's the best pure Java approach to hardware locking a license.

Not Knowing all of your requirements. For example, are you trying to uniquely identify a computer from all of the computers in the world, or are you just trying to uniquely identify a computer from a set of users of your application. Also, can you create files on the system?

If you are able to create a file. You could create a file and use the creation time of the file as your unique id. If you create it in user space then it would uniquely identify a user of your application on a particular machine. If you created it somewhere global then it could uniquely identify the machine.

Again, as most things, How fast is fast enough.. or in this case, how unique is unique enough.

I think you should look at this link ... you can make a mixed key using severalidentifiers such as mac+os+hostname+cpu id+motherboard serial number.

Michel GokanMichel Gokan

The usage of MAC id is most easier way if the task is about logging the unique id a system.

the change of mac id is though possible, even the change of other ids of a system are also possible is that respective device is replaced.

so, unless what for a unique id is required is not known, we may not be able to find an appropriate solution.

However, the below link is helpful extracting mac addresses.http://www.stratos.me/2008/07/find-mac-address-using-java/

For identifying a windows machine uniquely.Make sure when you use wmic to have a strategy of alternative methods. Since 'wmic bios get serialnumber' might not work on all machines, you might need to have additional methods:

Java Disk Serial Number

In the java programs I have written for release I used the motherboard serial number (which is what I beleive windows use); however, this only works on windows as my function creates a temporary VB script which uses the WMI to retrieve the value.
