Hiding of Confidential Data and its Retrieval using Advanced Algorithms and QR Authentication system

Abstract

In this era of digital world, with the evolution of technology, there is an essential need for optimization of online digital data and information. Nowadays, Security and Authenticity of digital data has become a big challenge. This paper proposes an innovative method to authenticate the digital documents. A new method of QR code is introduced here, which allows multiple encryption and decryption of digital data. In this paper, we propose a new method, where the resume of a candidate will be encoded in QR (Quick Response) Code in encrypted form, so that if an intruder tries to change the data in the resume then he cannot do that. This is because; the encryption key is unknown to him. Encryption changes data or information that is normally plaintext through the usage of an algorithm so that someone must possess certain knowledge to access it. This special knowledge is normally called a key. For example, something is encrypted if someone must enter a password to access it. Encrypted QR codes are QR codes that everyone cannot scan and access. They are not very common, since most QR codes are used in marketing, and the developers of those codes want them to be accessible by everyone. Secure QR codes can be made that make the scanner enter a password to be able to access the content. I. Introduction Quick Response (QR) code is a type of 2 dimensional matrix barcode, which gained popularity because of its large capacity to hold digital data and it can be integrated in any mobile devices. It can be applied to encrypt data in defense system, banking sector, mobile network.QR code was invented by DENSO CORPORATION in 1994. Approved as AIMI Standard in 1997 and ISO/IEC Standard in 2000. Adapted as an industry-wide standard code by AIAG, JAMA and JTA. High readability by a reader is pursued.QR code is a barcode which is readable by any camera-enabled smart phone. They are typically seen as a white square with black geometric shapes.Users point their phones at the QR code, scan it, and are then taken to the end data. This could be text, a website, a YouTube video, a podcast… QR Codes are two-dimensional bar-codes with unlimited potential for embedded information. The QR code was developed by the automotive sector for tracking parts and data associated with the parts. Unlike traditional bar codes commonly used in retail, the QR code is capable of storing mass information and links to digital media. The QR code is multifaceted and can function as a link or storage system for information. The QR codes are scanned by a digital device and the user is either provided with the information embedded in the QR code or routed to the link associated with the QR code. Link codes are common but the reach of QR codes is unlimited and these codes are gaining popularity in retail, web and mobile applications.
