Java Ring


Java ring

A Java Ring could also be a finger ring that contains a little microprocessor with built-in capabilities for the user, a sort of revolving credit that's wearable on a finger. The rings were built by Dallas Semiconductor. Java ring a stainless-steel ring,16-millimeters (0.6 inches) in diameter. It contains an inexpensive microprocessor in a stainless-steel i Button which runs JVM and it is preloaded with the applet. The Java Ring is a particularly secure Java-Powered electronic token. Java Ring has a number of real-world applications.  
A ring may be a personal thing that the user and only the user carries along anytime and anywhere in order that she will authenticate you in every situation. Since it has not been very popular these days, it’s really a new opening for sure. The main components are RAM (134 KB), ROM (32 KB), a real-time clock, and a java virtual machine (JVM). 

The JVM is that the “processor architecture” on which java bytecode is executed. It is mostly implemented in software, and available for an outsized sort of hardware platforms, starting from mainframe computers to mobile phones and little embedded devices.  

i Button

i button

An i Button may be a device with a microchip that's encased during a durable chrome steel enclosure measuring 16 mm thick and meant to resemble a button, hence the name. It is designed to be durable and mountable anywhere in order that it is often wont to carry up-to-date information, even in harsh outdoor environments. 
• The jewel of the java ring is that the iButton 
• i Button may be a computer chip enclosed during a thick chrome steel can.  
• it's originally called “touch memory devices they were later renamed as “i Button”.  
• Java ring uses a 1-wire protocol for communication with the host and therefore the iButton 
• The i Button may be a mechanical packaging standard that places a 1-Wire component inside a little chrome steel "button" almost like a disk-shaped battery.  
• Each i Button features a unique and unalterable address laser attached to its chip inside the can lid.  
• The address is often used as a key or identifier for every i Button 

Application/Use of Java Ring: -  

  • Access control to buildings and equipment.  
  • It secures the network log in using challenge/response authentication.  
  • Storage vault for user names and passwords.  
  • It is the user profile for rapid internet form-filling.  
  • It provides a digital signature or E-Commerce.  
  • Digital photo ID and fingerprint biometrics.  
  • The java ring is often wont to hold secret codes, credit card numbers, driver licenses, other wallet contents, and even some electronic cash.  
  • Its greatest promise of java ring is to dwell its capacity to interact with Internet applications to support stronger remote authentication and remotely authorized financial transactions easily.  

Advantages of Using Java Ring: -  

  • A Java Ring becomes a customized key to protected assets and knowledge. By touching the right key to an iButton reader, the specified event, like opening a lock is enabled.    
  • Java Ring provides authentication to users which are crucial for several applications. It is easier for the administrator to maintain the security infrastructure.  
  • The Java Ring provides an easy, secure way of identifying an individual or asset. It can function as an electronic serial number that's never duplicated.  
  • Java Ring is often a customized token and acts sort of a chickenfeed purse for one or multiple applications. They are perfect for a good sort of e-Cash function like mass transit systems, parking meters, gaming systems, vending, and fleet refueling.  

The disadvantage of Using Java Ring  

  • iButton (or java iButton) features a limited processor power and memory. For better performance and scalability, it's imperative to maneuver the processing load to the appliance server.  
  • Even though iButton is often purchased for the cheaper price, so as to function, it needs a receiver like a blue dot receptor which might be very expensive.  
  • A Java Ring-based system doesn’t automatically allow any user mobility. The problem with the Java Ring that a lot of the organizations don’t even know the existence of Java Ring.  
  • Since the limited amount of data are often stored which suggests a private might got to carry quite one Java Ring.  

Conclusion: -  

Although Java Rings aren't widely used yet now, such rings and similar devices could have a number of real-world applications and work to make your lifestyle more comfortable, such as starting your car and automatically adjust to your preferences.  
The key issue a few wearable computers (java ring) isn't whether it's a hoop or another form factor: the deciding point is that you simply will always have it with you.  

Hopefully, I will be able to help you at every step along the way.
