DATA SECURITY USING TEXT BASED GRAPHICAL PASSWORD AND QR CODE

Abstract

Conventional password schemes are vulnerable to shoulder surfing attack and many other attacks like
brute force attack and dictionary based attack. Traditional alphabetical and numeric passwords have disadvantages
from a usability standpoint, and these usability problems translate into security problems. The system combines the
applications effectively in a way to transfer data securely. System provides data security with the help of
ColourCombination authentication, and cryptography using QR Code Techniques. The universal technique for providing
confidentiality of transmitted data is cryptography. The system provides a method to encoding the data using QR Code.
The information is mainly present in the Colour Strip of 8 bits colour combination. In this system data is securely
transmitted with the help of 8 bit colours acting as security element thereby providing authentication using The QR
Code.
