SBVLC: Secure Barcode-based Visible Light Communication for Smart phones

ABSTRACT:

As an alternative to NFC technology, 2D barcodes have been increasingly used for security-sensitive applications including payments and personal identification. However, the security of barcode-based communication in mobile applications has not been systematically studied. In this paper, we propose SBVLC - a secure system for barcode-based visible light communication (VLC) between smart phones. We formally analyze the security of SBVLC based on geometric models and propose physical security enhancement mechanisms for barcode communication by manipulating screen view angles and leveraging user-induced motions. We then develop two secure data exchange schemes. These schemes are useful in many security-sensitive mobile applications including private information sharing, secure device pairing, and mobile payment. SBVLC is evaluated through extensive experiments on both Android and I OS smart phones.

In our application we have implemented the idea of QR code as password verification to overcome all the hacking issues. We have two modules as banker and the user. In the user module there will be two categories they are shopping and paying bill. In the shopping section user will shop the product and enter the card and bank details and send request to the banker regarding the transaction purpose. And in turn the banker module there are two categories they are the create OTP and the send OTP details. The banker will check the details of the user request regarding the purchase and all the card and balance details and prepare a password in the form of QR code. The password will be I the form of QR code and will be sent to the user through the mail service to the user personal mail id. In turn the user will pay the bill by loading the QR from the mail and scanning. On scanning the password will generate if the password matches with the banker details the transaction will become successful. Thus password hacking, key logging and eavesdropping issues will be overcome.

 

 

EXISTING SYSTEM:

Short-range communication technologies including near field communication (NFC) and 2D barcodes have enabled many popular smart phone applications such as contactless payments, mobile advertisements, and device pairing. Evolved from the RFID technology, NFC can enable reliable low-power communication between RF tags and readers. However, NFC requires additional hardware and has been supported by only a few smart phone platforms on the market. Recent studies have shown that NFC is subject to security vulnerabilities such as eavesdropping and jamming. Moreover, most existing barcode applications are based on a single barcode exchange, which is insufficient for establishing a secure communication channel. Whenever a user types in her password in a bank’s sign in box, the key logger intercepts the password. The threat of such key loggers is pervasive and can be present both in personal computers and public kiosks; there are always cases where it is necessary to perform financial transactions using a public computer although the biggest concern is that a user’s password is likely to be stolen in these computers. Even worse, key loggers, often root kitted, are hard to detect since they will not show up in the task manager process list.
