This document discusses biochip technology, including its uses for tracking animals and humans, how it works using radio frequency identification, and some applications and concerns. Biochips are microchips implanted under the skin for identification purposes. They are passive transponders that can store identification information and be read by a scanner. Over 7 million animals and 6 million humans have been implanted with biochips for identification. However, some worry that if kidnappers learn about the chips, they could harm people to access the information stored on the chips. The document proposes some solutions to address security and privacy concerns with widespread adoption of biochip technology.

2.  Introduction
 Biochip Technology
 Working of biochip
 Applications
 Problem of biochips
 Solutions for the biochips
 Conclusion

3.  “Biochips”- exciting future technology for
Computer science, Electronics & Biology.
 It was developed in 1983 for monitoring fisheries.
 Now it is used over 300 Zoos & 80 government
agencies in 20 countries.
 Yearly, 6 million recipients of prosthetic devices
and breast implants are “biochipped”.
 Over 7 million animals have been biochipped
 Major biochip companies are A.V.I.D (American
Veterinary Identification Devices), Trovan
Identification Systems.

4.  Biochip implant is a small (micro) computer chip,
inserted under the skin, for identification
purposes.
 Biochips system is radio frequency identification
(RFID) system.
 RFID system uses low-frequency radio signals to
communicate between the biochip and reader.

5.  It’s a new type of bio-security device to accurately
track information .
 No need of remembering pesky PINs, Passwords
& social security numbers.
 No need to carry the medical records to hospital &
cash/credit cards.
 Biochips have the capability of locating lost
children, wounded soldiers

6.  Transponder in biochips is of passive type,
contains no battery of its own.
 Advantage of passive transponder is, it has very
long life up to 99 years and no maintenance.
 Transponder consists of four parts
i) Computer micro chip
ii) Antenna Coil
iii) Tuning capacitor
iv) Glass Capsule

7. Microchip :
•It stores identification numbers from 10 to 15
digits long
•The ID number is etched via laser on to the
microchip
Antenna coil:
•It’s a simple coil of copper wire around a iron
core which receives and sends the signal from
reader
Tuning capacitor:
•It stores the small electric charge sent by
reader or scanner and activates the
transponder.
Glass capsule:
•It houses the entire transponder ;usually of the
size of a uncooked grain of rice measuring
about 11 mm in length and 2 mm in diameter.
•It is made of soda lime glass.

8.  It consists of an “exciter” coil which creates an
EM field via radio signals.
 It provides necessary energy (< 1/1000 of a watt)
to excite the implanted biochip
 Reader also carries a receiving coil that receives
transmitted code from the implanted biochip
 This is all takes places very fast (milliseconds)
 Reader contains the software to decode the
received code and result in an LCD.

10.  With a biochip tracing of person/animal, anywhere in
the world is possible.
 A biochip can store and update financial, medical,
demographic data, basically everything about a person
 A biochip leads to a secured E-Commerce systems
 Biochips really are potent in replacing passports, cash,
medical record

11.  Biochip as Glucose Detector
 Proposed principle of Glucose detection
 Biochip as oxygen sensor
 Biochip as an Blood Pressure sensor

12.  A chip implant would contain a person’s
financial world, medical history, health care —
it would contain his electronic life“.
 "It is very dangerous because once kidnappers
get to know about these chips, they will kill
people to find them.

13.  The Biochip must retain data only if it is placed in a
fluid medium like blood & not in any other medium.
 Generic model of biochips consists of only ROM
component because passport number, Bank card
number normally permanent in nature.
 This technique is suitable for identification of dead
bodies (murdered by the kidnappers) as it loses the
data about the social security number
 But the induction of RAM component in addition to
ROM is a mere solution.

14.  A chip implanted somewhere in human bodies might
serve as a combination of credit card, passport, driver's
license, personal diary.
 A chip inserted into human bodies might also give us
extra mental power.
