A multi-purpose image-based QR code is designed in this paper. There are four purposes for the generated code. In first purpose, basic with look of a host image an ingenious layout to be identified easier. second one, saliency region detection method adopted enhancing quality third embedded into further access image; Finally, visual cryptography-based watermarking applied case that specific use...

This article traces the history of machine-readable data encoding standards and argues that QR code has become an infrastructural gateway. Through analysis patents, corporate documents advertising, ethnographic observations, interviews with professionals, I describe global making argue convergence standards, mobile computing, machine vision algorithms, platform ecosystems led to emergence a new...

Counterfeit production is a threat for every genuine business causing damage to their brand image and stealing revenues. The aim of this paper topresenta novel method prevent counterfeit products using cryptography, QR code webservice. requires that original product manufacturer obtain cryptographic key pair, securely store private publish public on website as code. needs print unique item pack...

With the rapid popularization of QR code technology, colour is an important direction its development, making it great value to research a that can be read directly while improving data capacity. This letter proposes novel composite by combining coding and multiplexing technology. Based on actual demands high-capacity, this presents public identification information in form plain conceals secre...
