2. INTRODUCTION:
Finger ring that contains a small microprocessor.
Built-in capabilities for the user.
It is extremely secured .
It contains an inexpensive microprocessor in stainless
steel ibutton running a JVM and it is preloaded with
applet.
4. RAM & ROM :
RAM : 134kb
----> Program & data
ROM : 32kb
----> OS
5. iButton:
iButton is a computer chip thick stainless steel can.
Address etched onto its chip inside the can.
Address can be used as a key or identifier.
10. Components for iButton
application :
An iButton device
A host system
A reader/writer device to get information into and out
of the button.
A layer of software.
11. Blue Dot Receptors:
Provides a convenient pipeline for iButton - PC

15. SECURITY:
Armored with stainless steel for the hard knocks of
everyday use.
Personal Identification Number(PIN)
16. WORKING:
The Java Ring is in fact a Java smart card, which is
capable of running Java programs.
A serial reader connects to a computer's serial port.
17. Contd..
An applet written to run on the Java ring
follows a very simple structure.
The methods are as follows:
deselect -- another applet, or possibly this
one, is about to be selected
install -- installs the applet
process -- incoming APDUs arrive here
select -- called when a select command is
received
20. ADVANTAGES:
A very easy and convenient way for users.
More secure than using passwords.
Portable.
Ruggedness.
Wearable.
Provides real memory
21. DISADVANTAGES:
Cost of implementing is high.
Limited amount of information is stored.
The machine must support the same standard ibutton
reader interfaces.
22. CONCLUSION:
Durable because of its rugged and secure stainless
packing.
The iButton form factor permits attachment to a wide
variety of personal accessories that includes rings,
watchbands, key fobs, wallets, bracelets, and
necklaces, so the user can select a variation that suits
his or her lifestyle.
