  4. 4. INTRODUCTION • Java ring is a finger ring that contains a small microprocessor with built in capabilities for the user. • Java ring is a sort of a smartcard that is wearable on a finger • Java ring a stainless-steel ring,16-millimeters (0.6 inches) in diameter.
  5. 5. CONTINUED… • It contains an inexpensive microprocessor in a stainless steel iButton which runs JVM and it is preloaded with applet. • The java Ring is an extremely secure Java-Powered electronic token. • Java Ring have number of real-world application.
  6. 6. THE JAVA RING • Contains a tiny Java Virtual Machine • Implements the Java Card 2.0 API • Stores information in NVRAM ,ROM • Runs applets • Includes microprocessor, memory, clock and battery
  7. 7. JAVA RING IN ITS NATURAL ENVIRONMET..
  8. 8. COMPONENTS • Java Virtual Machine (JVM) • RAM • ROM • real-time clock • iButton • Blue dot reciptor
  9. 9. JAVA VIRTUAL MACHINE The java virtual machine is the piece of software that recognizes the java language and translates the byte Code.
  10. 10. RAM • Java ring contains 134kb of non-volatile random access memory . • This non-volatile random access memory offers high read/write speed. • It also provides rapid zeroization.
  11. 11. ROM • The java ring contains 32kb of ROM . • Special kind of operating system called e-commerce operating system is stored in the ROM
  12. 12. REAL TIME CLOCK • Real time clock gives the exact time of the day and it can run up to 10 years continuously . • It is driven by a constant 32KHz crystal oscillator. • In addition ,the frequency of the processor clock is not constant ,ranges from 10-20MHz. • This aspect prohibits hackers in obtaining the information from the iButton.
  13. 13. i BUTTON
  14. 14. i BUTTON… • The jewel of the java ring is the iButton. • iButton is a computer chip enclosed in a thick stainless steel can. • It is originally called “touch memory devices they were later renamed as “iButtons”. • Java ring uses 1-wire protocol for communication with the host and the iButton.
  15. 15. CONTINUED… • The iButton is a mechanical packaging standard that places a 1-Wire component inside a small stainless steel "button" similar to a disk-shaped battery. • Each iButton has a unique and unalterable address laser attached onto its chip inside the can lid. • The address can be used as a key or identifier for each iButton.
  16. 16. i BUTTON STRUCTURE
  17. 17. BLUE DOT RECEPTOR • The Blue Dot Receptors are iButton reader/probes that provide convenient pipeline into the PC for iButton-to-PC communication. • The receptor's cable connects to a USB, serial, or parallel-port 1-Wire adapter, whichever type of port you wish to use. • The receptor itself easily affixes to any accessible spot on the front of the PC. a

  19. 19. CONTINUED… • Key features: • It has a coiled cable for connecting iButtons to 1-Wire networks . • Adhesive pad for mounting on objects. • Supports for up to two iButtons at once. • Can be used with any Dallas Semiconductor port adapter
  20. 20. WORKING • Java Ring is programmed with the applets and the programming is done according to our application • Whenever the user pushes his ring on a ring reader(Blue Dot Receptor), the corresponding application will take place.

  23. 23. CONTINUED… • Information is transferred between your iButton and a PC with a momentary contact at up to 142kbps. • You simply touch your iButton to a Blue Dot receptor or other iButton probe, which is connected to a PC. • The Blue Dot receptor is cabled to a 1-Wire adapter that is attached to a spare PC port. 1-Wire adapters exist for USB, serial, and parallel ports.
  24. 24. SECURITY • The barrier substrate and the triple-layer metal construction techniques employed in the silicon fabrication effectively deny unauthorized access to the data stored in the NVRAM. If any attempt is made to penetrate these barriers, the NVRAM data is immediately erased. • Java rings are authorized through Personal Identification Numbers (PINs) so that no one can steal a person's ring and use that ring.
  25. 25. APPLICATIONS • The java ring can be used to hold secret codes, credit cards numbers, driver license, other wallet contents, and even some electronic cash. • Its greatest promise appears to lie in its capacity to interact with Internet applications to support strong remote authentication and remotely authorized financial transactions.
  26. 26. CONTINUED… • For opening the door • E-banking application • Logging in your PC • Providing security in your car • Used to fill forms
  27. 27. ADVANTAGES • The Java Rings are very easy and convenient for users. • It can function between -40C to+70C and in much harsher environment. • It has higher durability.
  28. 28. CONTINUED… • Easier for administrator to maintain the security infrastructure. • Provides real memory, more power, and a capacity for dynamic programming . • Provides authentication to user which is crucial for many applications.
  29. 29. DISADVANTAGES • The cost of implementing the system is high. • It needs a high level tools and method in order to program application efficently, reliabily,securily. • iButton has a limited processor capacity and memory , which means an individual might need to carry more Java Ring. than one
  30. 30. CONCLUSION • Although Java Rings aren't widely used yet, such rings or similar devices could have a number of real-world applications, such as starting your car and automatically adjust to your preferences. • The key issue about a wearable computer (java ring) is not whether it is a ring or another form factor: the deciding point is that you will always have it with you.
