(57) ABSTRACT A new framework for extending monochrome barcodes to color which offers
higher data rates is described. In one embodiment of the present invention, the framework …

We propose a color barcode framework for mobile phone applications by exploiting the
spectral diversity afforded by the cyan (C), magenta (M), and yellow (Y) print colorant …

All printed documents/credentials are potentially subject to counterfeiting and forgery.
Conventional counterfeiting solutions such as watermarking or printing using special-quality …

Considering incompatibility between the color QR code and the standard QR code decoder
and insecurity of information storage in the open network environment, this paper proposes …

Quick response (QR) code is a printed code of black and white squares that is able to store
data without the use of any of the electronic devices. There are many existing researches on …

Abstract The Quick Response (QR) code is an enhancement from one dimensional barcode
which was used to store limited capacity of information. The QR code has the capability to …
