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.

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

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.

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

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

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

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.

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.

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.

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.
