This document discusses digital jewelry, which embeds computing components like microphones, displays, and antennas into fashion accessories. It describes a prototype phone broken into pieces of digital jewelry that communicate wirelessly, including earrings with microphones, a ring with an LED display to indicate calls, and a wrist display. The Java Ring is highlighted as a programmable access device, containing a processor, memory, and software to interface with other devices. Potential applications include access control, authentication, passwords, and digital signatures. While the concept aims to make computers more wearable and convenient, challenges around charging and costs remain.

3. INTRODUCTION
 In the fast moving world we need the
communication systems very compact
and it must be with us in every walk of
our life
The combination of shrinking computer
devices and increasing computer power
has allowed several companies to begin
producing fashion jewellery with
embedded intelligence.

4. DIGITAL JEWELLARY
Digital Jewellery
next sizzling fashion trend of the
technological wave.
Digital jewellery is the fashion jewelry with
embedded intelligence.
“Digital jewellery” can help you solve
problems like forgotten passwords and security badges.

5. COMPONENTS
 Soon, “cell phones” will take a totally new form,
appearing to have no form at all.
 Instead of one single device, cell phones will be
broken up into their basic components and
packaged as various pieces of digital jewellery.
 IBM developed a prototype of cell phone.
 Consists of several pieces of digital jewelry.
 Works using Bluetooth wireless technology

6. COMPUTERIZED-JEWELRY PHONE AND
THEIR FUNCTIONS
Microphone
Receiver
Touchpad
Display
Circuit board
Antenna
Battery

7.  Speakers embedded into
these earrings will be the
phone’s receiver.
 These days many manufacturers
are developing things like
Bluetooth devices in the form of
pendants or earrings that people
can wear that help enhance heir
mobile phones, computers
PDAs, basically anything that
uses similar Technology

8.  Users will talk into the
necklace's embedded
microphone
 They transfer the information
in the forms of signals
 It consist of sensors by these
it will work
 It is mainly by blue tooth
technology

9.  Perhaps the most
interesting piece of the
phone, this "magic
decoder ring” is equipped
with LEDs that flash to
indicate an incoming call.
It can also be
programmed to flash
different colors to
identify a particular caller
or indicate the importance
of a call

10.  Equipped with a video
graphics array (VGA)
display, this wrist display
could also be used as a
caller identifier that flashes
the name and phone number
of the caller.

11.  The same ring that flashes for phone
calls could also inform you that e-
mail is piling up in your inbox.
 This flashing alert could also indicate
the urgency of the e-mail.
 On top of the ball that ring is a little
black users will move the cursor, in
the same way that the TrackPoint
button on a laptop is used.
 Displays will no longer be tied to
desktops or wall screens. Instead,
you'll wear the display like a pair of
sunglasses or a bracelet

12. DISPLAY TECHNOLOGIES
 The digital jewelry display, for instance, every alphabet
and number system has found representation within the
electronics realm and 'dot-matrix'
This could range from LED 7-segment, 16-segment, dot matrix, and other
programmable LEDs devices to LCDs, OLEDs, and other displays

13. JAVA RING
 The Java Ring can be programmed to give you access to every
door and device.
 The Java Ring is a stainless-steel ring, 16-millimeters
(0.6 inches) in diameter, which houses a 1-million-
transistor processor, called an iButton.

14. o The ring has 134 KB of RAM, 32 KB of ROM, which is
a piece of software that recognizes the Java language
and translates it for the user's computer system
 Dallas Semiconductor is developing a new Java-based,
computerized ring that will automatically unlock doors
and log on to computers

15. BLUE DOT RECEPTOR
 The Java Ring is snapped into a reader, called a
Blue Dot receptor, to allow communication between
a host system and the Java Ring

16. HIGHLIGHTS OF JAVA RING :
o Runs Java better (plus portions enhance Java Card 2.0)
 Careful attention to physical security
 Durability to stand up to everyday use
 High memory capacity (up to 134K bytes NV SRAM)
 Retail connectivity to 250 million existing computers

17. ADVANTAGES AND DISADVANGES
Advantages
 Java ring is wearable
 Completely controlled by the user
 Rapid Zeroization
 Personalization
Disadvantages
 Charging capabilities &Cost are just a sample of
problems

18. APPLICATIONS
 Access control to buildings and equipment
 Secure network login using challenge/response
authentication
 Storage vault for user names and passwords
 User profile for rapid Internet form-filling
 Digital signatures for e-commerce
 United States Postal Service Postal Security Device
for PC Postage downloadable over the Internet
 Digital photo ID and fingerprint biometrics

19. CONCLUSION
 The basic idea behind the digital jewelry concept is to
have the convenience of wireless, wearable computers
while remaining fashionably sound.
 It is hoped to be marketable soon, however, several
bugs remain. Charging capabilities and cost are just a
sample of the problems that lurk
