Increased Throughput SBVLC system using Color Barcodes

Color barcodes are used to increase the system throughput of the SBVLC system.2D barcodes have an advantage of significant penetration rate in mobile applications. This is largely due to the extremely low barrier to adoption almost every camera-enabled smartphone can scan 2D barcodes. As an alternative to NFC technology, 2D barcodes have been increasingly used for security-sensitive mobile applications including mobile 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 smartphone screens. On the other hand, the fundamental design principles of 2D barcodes make it difficult to add security features. SBVLC is a secure system for barcode-based visible light communication (VLC) between smartphones. Three secure data exchange schemes that used to encode information in barcode streams. These schemes are useful in many security-sensitive mobile applications including private information sharing, secure device pairing. Here the system throughput can be increased using color barcodes streaming. In terms of barcode design, by taking advantage of more colors, some new color barcodes are proposed to increase the capacity.
