1.ABSTRACT:
This work describes a ARM processor-based data logging system using
RedTaction to record the details of a particular person. The system is
simple to use the data of a particular system is stored in a transmitter which
will be in touch with a body of a person and a same data is prestored in a
data base when a person comes in a contact with receiver the entire data of
a person is fed to base system to be login and updated.
2.OBJECTIVE:
The objective of this project is to give a better security system to
transmit a data via body. Since there is no problem of hackers as our body
itself acts as transmission medium and can be used more in the fields
where there is a need to upgrade the security in times of high theft rate

4.METHODOLOGY:
This module consists of RedTacton transmitter, RedTacton
receiver, Driver, ARM controller unit and the Voice bank. RedTacton is a
HAN; body of human being is used for transmission of signals. RedTacton
transmitter consists of a DTMF encoder which generates both valid and
invalid signals and can be transmitted through human body through the
RedTacton receiver (DTMF decoder) for further processing. In RedTacton
receiver by the use of DTMF decoder the transmitted signal is identified.
The Redtaction transmitter consist a data of a person whose data is to be
logged in when he touch to a redtaction receiver the data is transmitted and
compares the corresponding data which is previously feded into controller.
As the transmitted signal is of very low voltage, buffers and drivers are
used to send the received signal to the electromagnetic switch.
Electromagnetic switch checks the received signal with the predefined valid
code. If an invalid code is received and detected in the switch then the buzzer
starts ringing indicating that an unknown person is trying to enter into a
particular location. If a valid code is received, then only the switch sends the
signal to the main control unit which is the microcontroller and data of log in
is updated.
5.ADVANTAGES AND DISADVANTAGES:
ADVANTAGES:
1.
RedTacton does not require the electrode to be in direct contact with the
skin.
2.
Can transmit data at a rate higher than that of peer technologies. (max. of
10Mbps) and Security is more.
3.
RedTacton transceivers are programmable and we can decide what to share
with whom and what devices you communicate with.
4.
Each communication occurs in separate channels.
5.
Transmission speed does not deteriorate even though the number of users
increases. And More secure than Bluetooth.
6.
Data loss during transfer is less
7.
Use of minimum amount of power (of some milli -volt range)
8.
Superior than infrared technology & Wi-Fi
9. No problem of hackers. It is very hard to pick up stray electronic signals
radiating from the body.
DISADVANTAGES:
1.
The obvious barrier to entry is that the cost and time to develop HAN TECH.
is very expensive.
2.
As a new technology HAN need to gain popularity among users to help pull
the technology into the marketplace instead of having it pushed upon them.
3.
Widespread marketing campaigns will need to be developed to highlight the
benefits of HAN technology to facilitate its adoption.
4.
It can be useful within few centimeters only
6.APPLICATIONS:
1.It can be used in corporate fields.
2.In bank security
3.In defense
7.CONCLUSION:
The proposed RedTacton based data logging has been
implemented successfully and is tested on hardware. Experimental results
verify the effective developed operation. When we compare RedTacton
with other technologies, it can give a better security since there is no
problem of hackers as our body itself acts as transmission medium and can
be used more in the fields where there is a need to upgrade the security in
times of high theft rate. And no need to carry id’s where the system
transmitter can fix to watch, chains or jewels.
