This paper investigates a novel approach to secret sharing using QR codes. The proposed QR code secret sharing approach exploits the error correction mechanism inherent in the QR code structure, to distribute and encode information about a secret message in a number of shares. Each share in the scheme is constructed from a cover QR code, and each share itself is a valid QR code which can be sca...

It is important to differentiate between various objects and places in the real world. Any Smartphone equipped with a camera can read the content of QR code directly. QR codes being a two dimensional codes are useful in storing the information .This information isn’t present in human readable form hence an individual cannot anticipate whether this is a valid information or a maliciously manipul...

Since the angular deviation produced when shooting a QR code image by a camera would cause geometric distortion of the QR code image, the traditional algorithm of QR code image correction would produce distortion. Therefore this paper puts forward the algorithm which combines corner detection with convex hull algorithm. Firstly, binaryzation of the collected QR code image with uneven light is o...

In view of the simple keys, time-consuming in encryption and decryption process and the loss of original function characteristics in encrypted image QR two-dimensional code, we adobe a kind of encryption method of QR code based on ECA state ring. In this method, the simple structure, highly parallel of elementary cellular automaton is being used. Operating each pixel point on the quick response...

For this study, we designed a QR Code Identity Tag system to integrate into the Turkish healthcare system. This system provides QR code-based medical identification alerts and an in-hospital patient identification system. Every member of the medical system is assigned a unique QR Code Tag; to facilitate medical identification alerts, the QR Code Identity Tag can be worn as a bracelet or necklac...

With the continued proliferation of smart mobile devices, Quick Response (QR) code has become one of the mostused types of two-dimensional code in the world. Aiming at beautifying the appearance of QR codes, existing works have developed a series of techniques to make the QR code more visual-pleasant. However, these works still leave much to be desired, such as visual diversity, aesthetic quali...

QR code is the type of matrix barcode, which was first designed for the automotive industry by Denso Wave in Japan. The QR Code system has become admired outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes. This paper take account of QR codes basics, its real time application in day to day life and research areas associated....

O artigo é um recorte da dissertação de conclusão do Mestrado Profmat desenvolvido na Universidade Federal Rio Janeiro (UNIRIO), apresentada em Agosto 2021 (SILVA, 2021). objetivo deste trabalho mostrar que códigos podem ser utilizados nas aulas matemática básica com a finalidade manter os alunos interessados disciplina e desenvolvermos alguns conteúdos forma concreta, trazer realidade para den...
