SBVLC: Secure Barcode-Based Visible Light Communication For Smartphone’s

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. Due to the visual nature, 2D barcodes are subject to eavesdropping when they are displayed on the screen of a smart phone. On the other hand, the fundamental design principles of 2D barcodes make it difficult to add security features. In this paper, we propose SBVLC - a secure system for barcode-based visible light communication (VLC) between smartphones. 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 iOS smartphones.

AIM

The aim of this paper is 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.

SCOPE

The scope of this paper is SBVLC is evaluated through extensive experiments on both Android and iOS smart phones.

EXISTING SYSTEM

The proliferation of smart phones puts a portable camera in everyone’s pocket, making eavesdropping much easier. This is exacerbated by widely spread use of surveillance cameras in public areas like shopping malls. On the other hand, the fundamental design principles of 2D barcodes make it difficult to add security features. First, a 2D barcode only contains a small amount of information and hence cannot simply adopt advanced encryption primitives. Moreover, most existing barcode applications are based on a single barcode exchange, which is insufficient for establishing a secure communication channel. Recently, several systems are designed to stream a series of barcodes between a LCD screen and smart phone camera. These systems can enable high-throughput ad hoc communication between smart phones; however, they are designed based on highly customized barcodes which are not widely adopted in practice

DISADVANTAGES

·      Due to the visual nature, 2D barcodes are subject to eavesdropping when they are displayed on the screen of a smart phone

·      The fundamental design principles of 2D barcodes make it difficult to add security features

PROPOSED SYSTEM

In this project, we investigate secure barcode based communication for smart phones. Due to the inherent directionality, the visible light communication (VLC) channel of barcode exchanges yields interesting security properties. We formally analyze the security of VLC based on geometric models and propose security enhancement mechanisms such as manipulating view angles and leveraging user-induced motions. We then develop three secure data exchange protocols that encode information in barcode streams. We believe that the proposed protocols are useful in many mobile applications including private information sharing, device pairing, and mobile payment systems, etc. further propose two secure communication schemes. The first scheme, two-phase message transfer scheme, is an ultra-lightweight solution to secure smart phone data exchange and mobile payment. The second scheme, all-or-nothing data streaming scheme, is tailored for secure temporary data transfer without key exchange. It adopts the secret sharing scheme to enhance the channel security it preserves the confidentiality of all the transmitted data, if the eavesdropper misses at least one barcode frame during the entire communication. Both proposed schemes are evaluated through extensive experiments on both Android and iOS smartphone platforms

ADVANTAGES

·      Our system achieves high level security and NFC-comparable throughput

·      The system can be used for private information sharing, secure device pairing and secure mobile payment, etc.
