University IoT Project: Biometric System Design and Implementation

This project report focuses on the Internet of Things (IoT) and its application in biometric systems. The report introduces the concept of IoT, highlighting the interconnection of physical devices with sensors and actuators for data exchange, and identifies the problem of security and identity verification in organizations. The solution proposed is a biometric system, which uses fingerprint, facial, or voice recognition for identification and authentication. The report details the features of such a system, including its ability to record attendance and save time. A diagram visualizes the system, and the report explains the working of a fingerprint scanner, including the components like ATmega328 and the process of data transfer and matching. The advantages and disadvantages of using biometric systems are discussed, including time-saving, enhanced security, and accountability, alongside the risks of security breaches and the need for robust systems. The report concludes that biometric systems, though with limitations, offer significant benefits in security and time management, and can be enhanced with artificial intelligence.

Topic of the project
The topic of the project is Internet of things
Introduction and the problem
The technology internet of things is defined as the interlinking of the physical device
such as the fan, TV, oven or any other electronic devices. These electronic devices are attached
with sensors or actuators which allow these devices to exchange data. These data contains the
instructions of the user on which these devices perform operations.
The following assignment is project related to Internet of things, the chosen project for
this assignment is biometrics system. The biometric is the machine which is used for security
purpose in identification and authentication services. These devices automatically identify and
recognize the identity of a particular person through different behavioral characteristics (Gubbi,
2013). The behavioral characteristics include fingerprints of thumb, facial, voice, eyes
recognition. In various organization where thousands of worker are working at a time, it is
difficult and time taking to check the identity of each employee whether he is working in that
company or not. If a person who is not the part of that organization enters the premises with the
intention of stealing the confidential data, he can succeed in his work if the organization does not
have a strong identity checking machine.
Solution with the features
The problem arising in the previous section is solved by the usage of biometric machine.
Nowadays every company install a biometric system at the entrance point of the office and each
employee has to give prove his identity in terms of voice, face, eye that he is working for that

organization. The biometrics captures the identity and matches with the registered employee
identity which can be vocal, iris, thumb if the match is successful then the person will be allowed
to enter or else he cannot enter the organization. Most organization uses the biometric for the
attendance purpose. The biometric records the entry and exit time of the employee during
identity check thus helping company to know whether the employee is late or early and can be
penalized according to the same (Mhaske & Patankar, 2013). Besides the attendance using
biometric saves time, easy to use and affordable thus it is the great machine to check the persons
identification in seconds.

Explanation of the working
To construct a simple biometric finger print scanner following things are required(Rao & Satoa,
2013):
 Fingerprint scanner (and JST connector)
 Serial LCD kit (w/ATmega328)
 ATtiny85
 NPN transistor
 Buzzer
 Speaker wire
 3D printed case
 Copper tape
 5V voltage regulator
 9V battery
 9V battery connector
 SPDT limit switch
The ATmega328 is a powerful processor which not only controls the LCD display but also can
act as audrino to exchange the data with the fingerprint scanner. It communicates at 3.3 volt the
component is soldered with the ATmega328 and the sample fingerprint is stored in ATmega328
in it fingerprints database. After the fingerprints the programming is performed for the LCD test
and for the blink test so that it will alert the user fingerprint is not registered (Bolle et al, 2013).
A serial data is transferred to the by the fingerprint scanner to the microcontroller. The code
received is then matched with predefined numbers stored in the flash ROM, and then a signal
high is send to the module 1 if the number becomes valid.

Pros and Cons of using biometric
The usage of biometric has various advantages:
Time
The biometric sensors take least time to check the identity of the person thus has lage
application in the big organization.
Application
Besides the finger biometric also has capability to scan the voice, iris, face thus provide
more security in the scanning of the identity.
Accountability
Biometric identification creates a concrete account trail to help establish accountability.
Each negative or positive action of the employee will be recorded and clearly documented by the
individual associated with it which reduces the possibility of system misuse and fraud (Xia et al,
2012).
Other advantage of using biometric is that easy to install , affordable and very simple to work on
it.
Cons of using Biometric system
Security
There are various links available online which shows how to forge a biometric system
therefore if a organization does not have a good biometric it can be easily hacked. In order to
install stronger biometric system greater budget is required (Das, 2013).

Reset
If the data of the biometric system is hacked or compromised with the security then there
is no way the data can be retrieved back.
Breaching
It is easy to breach the biometric if the someone presents the recorded voice of the
registered person then it can be easily opened.
Conclusion
From the assignment it can be Internet of things is used to connect the appliances which
contains an IP address. The biometric scanner which is the application of the Internet of things
has saved huge time in verifying the data of the user as it can do that in seconds. The usage of
biometric scanner has huge application in business sector as it can be upgraded to provide the
security to the data of the company. Though it has some limitation but it can be overcome
through usage of artificial intelligence in the syatem.
