3. INTRODUCTIONTOIoT
Internet of Things (IoT) is an ecosystem of
connected physical objects that are accessible
through internet.
IoT enforces –
 Communication
 Automation
 Information

4. PROBLEM DEFINITION
The security aspect of IoT connected devices is of higher significance.
For a product owner to hold an acceptable implementation of the smart lock,
we generalized the problems as follows -
☞ How to setup a smart lock that is sufficiently secure so that the breaching factor can be minimized
ensuring strong privacy?
☞ How to provide a user friendly interface and experience regardless of how complex the security
architecture is?
☞ How to provide a lock that is durable, reliable and efficient yet budget friendly?
☞ How to develop a lock that can keep logs of all ethical and suspicious attempts to unlock the door?

5. OBJECTIVES& GOALS
The main objectives of the proposed system are as follows –
 To provide a secure locking mechanism to the user that is trustworthy and acceptable.
 To provide an easy user interface to the user so that the operations with lock can be made hassle free.
 To develop a system which can communicate with the lock and keep all its logs may it be authenticated or
an unauthorized attempt.
 To develop a lock that is durable, robust and yet economical.
The proposed system implements the following functions –
 Will able to unlock the lock using a three factor authentication mechanism
 Will able to get the logs of all authorized and unauthorized attempts
 Will be able to add, remove and change user information on the database.
 Will be able to track faulty attempts as each events will be recorded.

6. MARKET STUDY
 The global smart lock market size was estimated at USD 559.4 million in 2016.
 The demand for smart locks is expected to exceed 135 million units by 2024.
 The demand for smart lock is
increased exponentially.
 Around 50% smart locks are used
In residential areas.
Adoption of sophisticated keyless
access devices is relatively more
conventional in mature markets.

10. SYSTEMANALYSIS& DESIGN
The proposed three factor authentication smart lock will provide a 3 step authentication process via
🔑 RFID, 🔑PIN  and 🔑a random 6-digit generated OTP.
Features
☞ Secure access to resources
☞ Fast and reliable
☞ Keeps logs of all attempts
☞ Easy and lucid UI
☞ Touch based for better UX
☞ Add multiple users
☞ Manipulate existing users
☞ Less space requirement
☞ User Privacy

13. SYSTEMIMPLEMENTATION
Sl No. Components Purpose
Raspberry Pi It is considered as the heart and the
brain of the system. It checks the RFID,
PIN and OTP data entered as an input,
sends signal to the relay to activate and
deactivate the lock accordingly.
Relay Module It works as a switch that works on
signal receives from raspberry pi to
drive the electric lock.
DC Power Module It satisfies the power need of the
system. It provides 5V to raspberry pi
and the relay module and 12V to the
electric lock.
RFID Reader It reads the data of RFID card or key
fob and fetches it to raspberry pi.
TFT Touch Screen It presents a GUI for the whole system
to interact with the user as well as
takes input such as PIN and OTP.

14. Conclusion
Thus, the iSecure – 3FA Smart Lock prototype designed and implemented
is an innovative physical securing mechanism. The system employs three
factor authentication (3FA) which makes it robust to bypass or break.
The event logging facility ensures that all the events along with
relevant data and time stamp are recorded for analytics, audit and
future investigations. The system deploys open source hardware and
embraces simple and affordable building blocks, thereby reducing the
overall cost.

15. The proposed system has much scope of futuristic improvements. The
smart lock can be customized for easy configuration such that any
number or any type of authentication factor can be included. The
authentication layers such as face detection, bio-metric, GPS, Voice
enabled and the likes can be included as desired. The proposed Smart
lock prototype can be embedded with tampered-proof, battery backup
along with power indications and similar mechanisms and necessary
notifications.
