A Directly Readable Halftone Multifunctional Color qr Code

Chinese Journal of Electronics 2023年第3期32卷 474-484页

作者： HUANG Yuan CAO Peng LYU Guangwu Information and Communication Engineering Beijing Institute of Graphic Communnication

Color quick response(qr) code is an important direction for the future development of qr code,which has become a research hotspot due to the additional functional characteristics of its colors as the wide application of qr code technology. The existing color qr code has solved the problem of information storage capacity, but it requires an enormous hardware and software support system, making how to achieve its direct readability an urgent issue. This paper proposes a novel color qr code that combines multiple types of different identification information. This code combines multiplexing and color-coding technology to present the publicly encoded information(such as advertisements, public query information) as plain code, and traceability, blockchain, anti-counterfeiting authentication and other information concealed in the form of hidden code. We elaborate the basic principle of this code, construct its mathematical model and supply a set of algorithm design processes, which breakthrough key technology of halftone printout. The experimental results show that the proposed color quick response code realizes the multi-code integration and can be read directly without special scanning equipment,which has unique advantages in the field of printing anti-counterfeiting labels.

Enhancing Security in qr Code Technology Using AI: Exploration and Mitigation Strategies

引用

International Journal of Intelligence Science 2024年第2期14卷 49-57页

作者： Saranya Vaithilingam Santhosh Aradhya Mohan Shankar Department of Information Technology University of the Cumberlands Williamsburg KY USA

The widespread adoption of qr codes has revolutionized various industries, streamlined transactions and improved inventory management. However, this increased reliance on qr code technology also exposes it to potential security risks that malicious actors can exploit. qr code Phishing, or “Quishing”, is a type of phishing attack that leverages qr codes to deceive individuals into visiting malicious websites or downloading harmful software. These attacks can be particularly effective due to the growing popularity and trust in qr codes. This paper examines the importance of enhancing the security of qr codes through the utilization of artificial intelligence (AI). The abstract investigates the integration of AI methods for identifying and mitigating security threats associated with qr code usage. By assessing the current state of qr code security and evaluating the effectiveness of AI-driven solutions, this research aims to propose comprehensive strategies for strengthening qr code technology’s resilience. The study contributes to discussions on secure data encoding and retrieval, providing valuable insights into the evolving synergy between qr codes and AI for the advancement of secure digital communication.

On the Computing of the Minimum Distance of Linear Block codes by Heuristic Methods

引用

International Journal of Communications, Network and System Sciences 2012年第11期5卷 774-784页

The evaluation of the minimum distance of linear block codes remains an open problem in coding theory, and it is not easy to determine its true value by classical methods, for this reason the problem has been solved in the literature with heuristic techniques such as genetic algorithms and local search algorithms. In this paper we propose two approaches to attack the hardness of this problem. The first approach is based on genetic algorithms and it yield to good results comparing to another work based also on genetic algorithms. The second approach is based on a new randomized algorithm which we call 'Multiple Impulse Method (MIM)', where the principle is to search codewords locally around the all-zero codeword perturbed by a minimum level of noise, anticipating that the resultant nearest nonzero codewords will most likely contain the minimum Hamming-weight codeword whose Hamming weight is equal to the minimum distance of the linear code.
