Abstract: Nowadays, Security system is a major concern everywhere and for this concern various access are in place to address this dispute. Additionally, terrorism, unauthorized access to places has become a major issue. With this consideration, a design and prototype of digitalized smart security voice password locking system has been conferred in this project.
This project portrays to design and physiques a low cost-effective and malleable voice based
digitalized security and monitoring system with the aid of an integrated ARDUINO and wireless protocol
connectivity for access and to control of bank locker and home remotely using Android-based Smartphone voice
app. The objective of this project is to diminish the existing challenges and troubles confronted by outwardly
debilitated individuals in locking system. It also indulges physical security with voice password using android
application. It can be used in many real time applications such as bank, home and industrial application.
Keywords: Bluetooth, RF transmitter and receiver, GSM, Voice App, LCD, Motor.
INTRODUCTION:
Security is of primary concern and in this busy,
competitive world, human cannot find ways to furnish security
to his confidential belongings manually. Instead, he finds an
alternative which can affords a fully fledged security as well as
atomized. In the ubiquitous network society, where individuals
can effortlessly access their information anytime and
anywhere, people are also endured with the risk that others can
easily access the same information anytime and anywhere.
Because of this risk, personal identification technology, which
can distinguish between registered legitimate users and
imposters, is now spawning interest.
Currently, passwords, Personal Identification
Numbers or identification cards are used for personal
identification. However, cards can be embezzled, and
passwords and numbers can be speculated or obliterated. The
present scenario to exert a bank locker is with locks which are holding keys. By this we can’t say that we are going to furnish
good security to our lockers.
The locking system is an imperative prerequisite for
all. The locking systems are traditionally the mechanical locks
that are negotiated adopting keys. Such types of systems have
demonstrated to be vulnerable for key replication and intrusion
by various ways there by flawing security. It is observed that
bank strong rooms, bungalows, houses, shops and repositories
aspect security breaches lead to disastrous effects provoking
huge financial catastrophe. Apart from that, it also leads to loss
of sensitive and confidential information. The traditional
locking mechanisms are not good enough to diagnose any
pirated access, security breach and do not provide solid
279
In order to enhance security and authentication,
electronic locking systems are devised. Encrypted and secured
smart lock system can be connected to GSM and Bluetooth.
Now, smart phone is advanced for various applications other
than phone calls and messages. With mobile operating system
and internal applications, we can remotely supervised voice
locking system for bank and many other real time applications.
OBJECTIVE:
key. For safety purpose, we had upgraded our security system.
In recent times, technology is developed with the enhancement
of internet and also we had moved to wireless communication
for locking systems. Keypad electronic locking system is
prominent. In this system, we do not need any keys, because we
use passwords and pin codes for locking system. But it has
many detriments like forgetting the password, hacking of
password, unable to open the door in case of power failure.
A Biometric system is a technological system
which adopts information about a person to pinpoint that
person. For security purpose, biometric systems such as face
recognition, fingerprint verification, iris / retinal verification
etc have been used. Biometric fingerprint locking system
affords a way to grab an identity point. Even though, this
system is extremely secure, there is a possibility of cloning.
Face recognition system is the reasonable technology which
works by correlating the tabbed facial expressions with the
given image with face. But 2D recognition of face is affected by changes in person’s appearance like person’s hair, age,
lighting in environment, facial expressions etc. Biometric iris
recognition contributes pattern recognition techniques based on
high resolution and distortion _ free images of iris of human
eye. Because of it very low margin of error and fast speed, this
system is now one of the most trusted system. In retinal scan
biometric technique, we use the unique pattern on a person’s
retina blood vessels. Biometric system improves security and
cannot be forgotten or lost. But these systems are not hundred
percent accurate. Because environment and usage can affect
measurements. To overcome those problems, we have
considered a voice password based security lock system using
Smartphone voice app.
PROPOSED SYSTEM:
A voice password will be preceded to the locker
system via Bluetooth or Wi-Fi using android app. Then the
micro controller device compares the passwords with the
programmed password. If the word is correlated, then the
locker system will susceptible, otherwise micro controller circulates the admonition message to the authenticated person’s
mobile number, using GSM and the locker will be endured in
locked position. The main convenience of this system is that it
can be controlled by the user at a appropriate distance. An
android app is also advanced to allow the user to authenticate
and regulate the system to approach all the features. It will be
used for word recognition by communicating with the locker
device.

LOCKER ROOM –RECEIVER
WORKING PRINCIPLE:
This system works by mailing the voice password to the micro controller device.”ARDUINO ATMEGA 328” using
the mobile application. This mobile app is hooked up to the
ARDUINO device via Bluetooth or WIFI. The power supply
will be handed down to the ARDUINO device which collocate
and inscribe the password.LCD display is used to acquaint
information about the status of the password.
RF transmitter acquiesces and amend password to
transmit the signal. RF transmitter bears the signal to the RF
receiver which then consigns to ARDUINO device. The
ARDUINO device where the password is already programmed
in it compares the given signal with the stored signal. Relay
driver circuit is used to lock/unlock the bank locker. If the
password is matched the lock will be susceptible, otherwise the status message will be circulated to the authenticated person’s
mobile number using GSM modem and the lock remains in the
same state.

HARDWARE DESCRIPTION:
BLUETOOTH HC05:
Bluetooth module HC05 is adopted in a
MASTER/SLAVE configuration, making it a immense
quick-fix for wireless communication. The enjoyer can benefit
it, quietly , for a serial port reinstatement to inaugurate
affliation amid Multipoint Control Unit and GPS,PC to your
embedded enterprise.

DRIVER CIRCUIT:
It is a electrical circuit adopted to jurisdict
another circuit or components such as high power transistors ,
LCD and so on.
They are customarily benefitted to oversee current
streaming via a circuit or to curb other aspects such as other

In laptops to keep information confidential.
CONCLUSION:
Most of the security system have several
loopholes which could be broken down to gain access to the
desired places and the environment. Hence, the digitalized
smart security system is a unique combination indulging
absolute solution for various aforesaid security features to
problem of security. The system has been successfully
implemented and the aim for security system is achieved
without any deviation. There is a lot of future scope for this
project because of its security capacity.
