RED TACTON IN BIOMETRICS

1.ABSTRACT

Red Tacton is a Human Area

Networking technology that uses the surface

of the human body as a safe, high speed

network transmission path. The human body

acts as a transmission medium supporting

half-duplex communication at 10Mbit/s. It

uses the small electric field on the surface of

the human body and then uses this electric

field for further transmissions. Red Tacton

takes wireless communication a step further

by replacing the radio waves used for

transmission over Bluetooth, IR and similar

technologies with the minute electrical field

emitted by the human body. This technology

paves the way for a new breed of accesscontrol systems that are not based on remote

controls or access cards that rely on radio

waves that could be interfered with. This

paper deals with usage of Red Tacton in

biometrics by placing a bio-chip inside the

wrist. The person with the chip is only

allowed to open the door or access the data.

If this technology is implemented, it will be

the safest technology to be used for

biometrics. The weak electric field used

does not affect the human body. The

connection is not initiated until the person

physically touches two different Red

Tacton-enabled devices, when the person

touches the device the circuit is fulfilled, and

then authentication is verified. This

technology can be used where there is need

of high security. Red Tacton could be

installed on doors, cabinets and other

locations calling for secure access, such that

each secure access could be initiated and

authenticated with a simple touch. At the

same time, all the transaction details and

relevant user attributes (personal identity,

security clearance, etc.) could be logged by

the security system.

2.INTRODUCTION

NTT, the Japanese telecoms group,

and the team of scientists invented the Red

Tacton system. "Tacton" refers to the

communication starts by touching (Touch),

leading to various actions (Act on). We then

added the color red to convey the meaning

of warmth in communication. Combining

these phrases led to the name, "Red Tacton".

Human Area Networking (HAN), a network



where communication takes place via Red

Tacton transceivers embedded in devices

like PCs and cameras and in tags carried in.

The connection is not initiated until the

person physically touches two different Red

Tacton-enabled devices, say, a laptop and a

printer. Red Tacton does not require the

electrode be in direct contact with the skin.

High-speed communication is possible

between two arbitrary points on the body.

Red Tacton enables new generation of user

interface based on totally natural human

actions such as touching, holding, sitting,

walking, or stepping on a particular spot.

In the past, Bluetooth, infrared

communications (IrDA), radio frequency ID

systems (RFID), and other technologies

have been proposed to solve the “last meter”

connectivity problem

.

However, they each have various

fundamental technical limitations that

constrain their usage, such as the precipitous

fall-off in transmission speed in multi-user

environments producing network

congestion. Human Area Networks performs

communication within the much smaller sphere of ordinary daily activities– the last

one meter. NTT’s Red Tacton is a break-

through technology that, for the first time,

enables reliable high-speed HAN which

provides uninterrupted services based on



human-centered interactions and therefore

more intimate and easier for people to use.

A Red Tacton transmitter couples with

extremely weak electric fields on the surface

of the body. The weak electric fields pass

through the body to a Red Tacton receiver,

where the weak electric fields affect the

optical properties of an electro-optic crystal.

The extent to which the optical properties

are changed is detected by laser light which

is then converted to an electrical signal by a

detector circuit.

3.WORKING

Red Tacton takes a different technical

approach. Instead of relying on

electromagnetic waves or light waves to

carry data, Red Tacton uses weak electric

fields on the surface of the body as atransmission medium. Using a new super-

sensitive photonic electric field sensor, Red

Tacton can achieve duplex communication

over the human body at a maximum speed

of 10 Mbps.

1. The Red Tacton transmitter induces a

weak electric field on the surface of the

body.

2. The Red Tacton receiver senses changes

in the weak electric field on the surface of

the body caused by the transmitter.

3. Red Tacton relies upon the principle that

the optical properties of an electro-optic

crystal can vary according to the changes of

a weak electric field.

4. Red Tacton detects changes in the optical

properties of an electro-optic crystal using a

laser and converts the result to an electrical

signal in a optical receiver circuit.

positioning of Red Tacton with respect to

existing communication technologies. The

focus on ubiquitous service has brought

about the shortening of distances in

communication. Red Tacton is positioned as

the last 1m solution to ultimate close-range

communication.

5. IMPLEMENTING RED TACTON IN

BIOMETRICS

Touching, gripping, sitting, walking,

stepping and other human movements can

be the triggers for unlocking or locking,

starting or stopping equipment, or obtaining

data.

The biometrics can be done by

placing a bio-chip inside the hand, which is

a red tacton reciever. When the

authenticatve person touches the door

handle, from the transciever the signals flow

through through the body and and checks

the bio-chips for authentication. If bio-chip

is present then it checks whether the person

is allowed then the door opens or else the

door never opens at any means.

Using Red Tacton, communication

starts when terminals carried by the user or

embedded in devices are linked in various

combinations through physical contact

according to the human’s natural



movements. The technology uses a

transmission path established between the

body of a person carrying a Red Tacton card

key and a Red Tacton transceiver installed

in, for example, a doorknob or floor. The

person is automatically identified when they

touch the doorknob or walk on the floor, and

the transmission path is disconnected when

the body and transceiver physically separate.

With this technology we can lock our house

by just touching the door knob. The

transmission doesn’t enter the skin but is

merely carried across the surface, not

exposing the user to more electricity. In

addition, the transceiver is covered with an

insulation layer. In addition to the human

body, various conductors and dielectrics can

be used as transmission media. Also

carrying a mobile Red Tacton-capable

device in one’s pocket, ID is verified and the

door unlocked when the user holds the

doorknob normally. Secure lock

administration is possible by combining

personal verification tools such as

fingerprint ID or other biometric in the

mobile terminal.

If this technology

implemented, then this will be great

milestone in the field of biometrics.

6. ADVANTAGES

The benefit of Red Tacton -

compared to transmission technologies using

radio waves - is that transmission speed does

not deteriorate in congested areas where

many people are communicating at the same

time. A Red Tacton receiver in a cabinet

where important documents are stored

enables lock administration and keeps a

record of who accessed documents at what

time. Carrying a mobile Red Tacton-capable

device in one's pocket, ID is verified and the

door unlocked when the user holds the

doorknob normally. Outside the office, Red

Tacton offers a host of communication

options that might come in really handy. For

example, it lets you transfer pictures from

your camera just by touching the PC while

the camera is around your neck. And since

data can pass from one human body to

another, you may also swap electronic

business cards by shaking hands.

7. CONCLUSION

Human society is entering an era of

ubiquitous computing, when networks are

seamlessly interconnected and information

is always accessible at our fingertips. Red

Tacton is a break-through technology that,

for the first time, enables reliable high-speed

HAN. The advent of Red Tacton technology

by NTT is in itself revolutionary, which will



likely be targeted for use in applications

such as wireless headphones, wearable

medical devices, security applications,

point-of-sale interactions etc. This could get

as simple as two people equipped with Red

Tacton devices being able to exchange data

just by shaking hands. Red Tacton will

emerge as a technology that we use in our

day to day life in the near future.
