JAVA RING WITH IMPLEMENTATION.ppt

  1. 1. 1 BY MALINI.M SOWNDRYA.G 3RD CSE
  2. 2. INTRODUCTION  Digital jewellery is the fashion jewelry with embedded intelligence.  Each piece of jewelry will contain a fraction of the components found in a conventional mobile phone.  Together, the digital-jewelry cell phone should work just like a conventional cell phone.  The digital jewellery are Braclets , chains, necklace, ear rings, java ring etc,..  Among them java ring is compact and easy to carry anywhere and it is also secure the information with unique ID. 2
  3. 3. WHAT IS JAVA RING ? • Java ring is the finger ring that contain a small microprocessor with build-in capabilities for the user, a sort of smart card that is wearable on the finger. • The main objective of the Java Ring is to maintain security and portable. COMPONENTS:  134KB of RAM  32KB of ROM  Real Time Clock  Java Virtual Machine  iButton  Blue Dot Receptor 3
  4. 4. 4 WHY JAVA RING ? Only by JAVA it is supported to all OS. That why even supported for Ecommerce OS(e-cash). By JVM ,it supports automatic garbage collection for efficient reuse of memory space. An applet written to run on the java ring follows a very simple structure.
  5. 5. IMPLEMENTATION OF JAVA RING • Java Ring is used for the security purposes and also used for authority permissions. • For example ,in a family son , father, mother and other members are not anticipate about the speed limits. • So by the use of java Ring is to limit the features and speed in car to avoid accidents. 5
  6. 6. IMPLEMENTATION OF JAVA RING • By the use of Java Ring the unauthorized peoples cannot use or access the device. And there is personal identification number(PIN).so no one can do mischievous behaviour can be done, even it is lost. • The java Ring is used for the security purposes. • In future ,the java Ring is used to start the car by unique ID. 6
  7. 7. REQUIREMENTS OF JAVA RING • The Java Ring has 134KB of non volatile Random Access Memory(RAM),by this it offers high read/write speed. • Rapid erasing of the SRAM memory is known as zeroization. When an iButton detects any intrusion, it erases its private keys leading to zeroization. • The Java Ring has 32KB of Read Only Memory(ROM) and a special kind of OS called E-Commerce OS is stored in ROM. • In Real Time Clock,the frequency of the processor clock is not constant that ranges from 10-20MHz.This aspects prohibits the hackers in obtaining the information from iButton. 7
  8. 8. REQUIREMENTS OF JAVA RING • Java Ring uses the 1-wire protocol for communication with the host and the iButton. • Java iButton is designed more compatible in java card 2.0 standard processor. • The iButton memory can be read or written with a momentary contact to the "Blue Dot" receptor provided by the adapter. • The lifetime of java Ring is atleast for 10 years. 8
  9. 9. PICTORIAL REPRESENTATION 9
  10. 10. WORKING AND APPLICATION • Java Ring is programmed with the applets ,whenever the user pushes the ring on the ring Reader(Blue Dot Receptor) the corresponding application take place. • Communication is based on APDU format. APPLICATIONS:  To unlock the cars/doors/computers .  Secure way of identifying the asset.  Banks , authorized areas  e-cash  Useful to carry informations even URL’s. 10
  11. 11. ADVANTAGES AND DISADVANTAGES ADVANTAGE: * Many information and passwords carried in different devices is replaced in single Java Ring. * Higher durability. * It functions even in -40C to +70C,in harsher environment. * It supports Dynamic programming. * cost negligible. * Asset management ,access control,e-cash etc.., DISADVANTAGE: * Many peoples don’t aware of it. * iButton has a limited processor power and memory. * High level tools and method is required to program application efficiently and reliablity. 11
  12. 12. CONCLUSION • The key issue about a wearable computer (Java Ring ) is that whether it is a ring or another form factor : the deciding point that always that will be with you. 12
