SECURED QR CODE
 PANKAJ JESWANI

INTRODUCTION
• QRCodes which Encode AES Encrypted user Information with One
Time Password.
• Similarities and differences between the QRLogin systems and
traditional OTP systems.
• Developments within two factor identification systems are
significantly increasing the application of security systems to
protect personal information.
• Our implementation is about new authentication scheme for secure
OTP distribution in net banking through QR codes.

INTRODUCTON
Problem Definition
• To avoid remembering username and password and also to ease
online transactions, QRLogin is developed.
• The main aim is to provide secured login systems which also
perform online transactions. The QRLogin includes 2D barcode
‘QRCode’ which consists of encrypted user information with time-
sensitive One Time Password (OTP) by using well known
Asymmetric Encrypted Standard (AES) algorithm.
• The objective of our project is to come up with banking website and
online shopping website that implement and demonstrates how QR
Code can be used with Encryption algorithms to ensure data
security as it provides dual security with data optimization.

INTRODUCTON
Relevance of Project
• Our project “Secured QRCode” includes Encryption which changes
data or information that is normally plaintext through the usage of
an algorithm so that someone must possess certain knowledge to
access it.
• The bank can make Secured QR codes of Costumers which includes
confidential data such as user information and one time password.
This means people outside the bank cannot decode the Encrypted
QR code without unique key.

INTRODUCTION
Scope of the Project
• QRLogin system revolutionizes web site login and
authentication. It eliminates many problems inherent in
traditional login techniques.
• It is more secure as it involves AES encryption technique and
it is easy to use also gives freedom from remembering so
many username and password for different websites.
• The simple and straightforward SECURED QRLogin system
yields a surprising array of features and benefits and can be
used in various applications like e-commerce, e-retail, e-
booking, e-learning and many more

KEY PROCESS
• Encryption & Decryption
• QR-Code Generation
• QR-Encoding
• Decoding

ENCRYPTION & DECRYPTION
• A message that is completely readable and is in no
way scrambled or disguised is called plaintext. Plaintext
is unencrypted data.
•Encryption is the process of scrambling or disguising
plaintext by applying a cryptographic algorithm to
produce cipher text.
•Cipher text is encrypted data.
•Decryption reverses the encryption process and turns
cipher text back into its original plaintext form

QR CODE GENERATION
• To create a QR code, we need string of data in this case the
encrypted message.
• The method is discussed in details below:
• The Encrypted file, which is created using the method AES is
now treated as the input file and the string is extracted from
the file to generate the QR Code.
• Step 1: call function file_read(output_file)
• Step 2: call function generate_QRCode( str[] )

QR CODE DECODING
• We here follow the reverse process of the above generateQRCode()
Algorithm to detect the QR Code Image using Library Class and get
back the encrypted message.

Design Approach
• PHP
• YII Framework
• XAMPP

PHP (Hypertext Pre-Processor)
 PHP is a scripting language designed to fill the gap
between SSI (Server Side Includes) and Perl, intended for the
web environment. Its principal application is the
implementation of web pages having dynamic content.
 PHP is currently divided into two major versions: PHP 4 and
PHP5 , although PHP 4 is deprecated and is no longer
developed or supplied with critical bug fixes. PHP 6 is
currently under development.

YII(Yes It Is)
• Yii is an open source, object-oriented, component-based MVC PHP web
application framework. Yii is pronounced as "Yee" and it's an acronym for “Yes
It Is!”

XAMPP
• XAMPP is a free and open source cross-platform web server
solution stack package, consisting mainly of the Apache HTTP
Server, MySQL database, and interpreters for scripts written in
the PHP and Perl programming languages.

DEMONSTRATION
• Shopping Cart [Whole Demonstration]
• QR Code Auth System [QR Login System]
• QR Decoding [Decoder]

CONCLUSION
• In our project “Secured QRCode” we have proposed a secure and
reliable authentication scheme for net-banking through QR code
based OTPs. In recent years there has been a steep increase in the
number of net-banking users.
• Hence the proposed system satisfies the high security requirements
of the online us and protects them against various security attacks.
Also the system does not require any technical pre-requisite and
this makes it very user-friendly.
• Hence QR code proves to be versatile at the same time beneficial
for both the customers in terms of security and vendors in terms of
increasing their efficiency. Hence it is most widely used to advertise
and market the products by most businesses.

CONCLUSION
• In future, we will like to enhance our project by creating an android
application which will be used as way of retrieving OTP by just
scanning a QRCode.
• It will be more easier and at the tip of the user’s fingers as all the
bank transactions will be done by Smartphone which will save users
time and will be more secure than traditional transaction system.
