Abstract: The quick response code (QR) has become most popular barcode because of its larger data capacity and increased damage resistance. Barcode scanners can easily extract information hidden in the QR code when scanning data forms. However, some confidential data stored directly in QR codes are not secure in real world QR apps. To proposed approach to visual secret sharing scheme to encode a secret QR code into distinct shares. In assessment with other techniques, the shares in proposed scheme are valid QR codes that may be decoded with some unique that means of a trendy QR code reader, so that escaping increases suspicious attackers. An existing sharing technique is subjected to loss of security. On this premise, consider the strategy for (k, n) get to structures by using the (k, k) sharing occurrence on each k-member subset dependent on specific relationship. In addition, the secret message is recovered with the aid of XOR-ing the qualified shares. This operation which can effortlessly be achieved the use of smartphones or different QR scanning gadgets. Contribution work is, working on optimal partitioning methods and compare original message with shared message using hashing techniques. Keywords: Hashing, partitioning algorithm, error correction capacity, high security, Quick Response code, visual secret sharing scheme

O massivo uso de smartphones está provocando a incorporação destes aparelhos para funções aquém da comunicação. Seja para buscar informações, comprar produtos ou localizar-se em lugares não habituais, os smartphones vem substituindo outros recursos, principalmente devido sua mobilidade. Diante disso, o potencial deste aparelho para práticas educativas, pedagógicas e turísticas é corroborado através do relatório produzido pelo Hosteltur (2013), que, ao elencar as tecnologias que estão afetando a forma que o turismo é praticado, diagnosticou que o acesso a sites de museus, cresceu de 5% em 2011 para 30% em 2013, tendendo a se estabilizar em 50% a médio prazo. Além da navegação na internet, os smartphones oferecem outras possibilidades, através da instalação de aplicativos de acordo com interesses individuais. Diante deste contexto, considera-se a necessidade de aproximar o conhecimento científico de forma holística, ao descrever que: a cada dia erguem-se vozes para denunciar a distância que separa o conhecimento da vida, pois a forma como se desenvolve a educação acentua o isolamento do sujeito a respeito de sua realidade. Sob esta perspectiva, objetivou-se com este estudo desenvolver códigos bidimensionais – QR Code (Quick Response Code), que contenham informações sobre atrativos, visando educar os visitantes in situ. Os QR Codes, criados com objetivo de aumentar a quantidade de dados contidos em códigos de barras convencionais, ocupando menor espaço após sua impressão, passou a ser amplamente utilizados em diferentes segmentos ao longo da última década. Assim, utilizou-se como ferramenta para a gerar estes códigos o software invertexto, no qual foram criadas mensagens educativas que auxiliam o visitante a compreender e interpretar a origem das formações rochosas do Parque Estadual de Vila Velha – PEVV (PR), nas cores branca e verde para integrá-los com menor impacto ao meio ambiente e índice de confiabilidade mínima de 93% para os três principais sistemas operacionais atuais. Os resultados demonstraram que os QR Codes podem ser confeccionados em placas retangulares e verticais, nas dimensões de 23 x 20 cm, dispostas a aproximadamente 80 cm do solo, no decorrer da trilha de acesso à formação principal da Unidade de Conservação. Por fim, acredita-se que o uso de smartphones e sua interação com o meio ambiente por meio da tecnologia poderá despertar a curiosidade dos visitantes em descobrir o que os códigos ‘escondem’, estimulá-los a aprender de forma lúdica e incentivá-los à conservação do local, conscientizando-os das fragilidades existentes no PEVV. Symbiosis between mobile technology and natural heritage: an educational proposal ABSTRACT TThe massive use of smartphones is leading to the incorporation of these devices to function beyond communication. It’s used to looking for information, to buy products or locating in unusual places. Thus the smartphone is replacing other resources, mainly due to their mobility. The potential of this device for educational, pedagogical and tourist activities is stated out by the report produced by Hosteltur (2013), which had listed the technologies that are affecting the way that tourism is practiced and diagnosed that access to museum sites increased from 5% in 2011 to 30% in 2013, tending to stabilize at 50% in the medium term. In addition to web browsing, smartphones offer other possibilities to use by installing applications according to individual interests. Given this context, it was based in the need to bring scientific knowledge holistically, it is important to fill the gap between the knowledge of life, because the way that develops education accentuates the isolation of the subject about his reality. From this perspective, the aim of this study was to develop two-dimensional codes – QR Code (Quick Response Code), containing information about attractions, aiming to educate visitors in situ. QR Codes, created in order to increase the amount of data contained in conventional bars, but occupying less space after printing, became widely used in different segments over the past decade. The tool that it was used to generate these codes was the invertexto software. Educational messages were created to help the visitor to understand and interpret the origin of the Parque Estadual de Vila Velha – PEVV (PR, Brazil) rock formations. It was used the white and green colors, to integrate them with less environmental impact, beyond the minimum reliability index of 93% for the three major current operating systems. The results shows QR codes with a rectangular form and they were made in vertical signals, with the dimensions of 9.05 x 7.87 (in), arranged at approximately 31.49 (in) above the ground. They could be located at the main trail formation at PEVV. Finally, it is believed that the use of smartphones and their interaction with the environment through technology may arouse the curiosity of visitors to find out what the codes 'hide', encouraging them to learn, making them aware about the potential impacts at PEVV. KEYWORDS: Mobile Technology; Natural Heritage; Pedagogical Tourism; QR Code; Parque Estadual de Vila Velha.

QR code (quick response code) is used due to its beneficial properties, especially in the mobile payment field. However, there exists an inevitable risk in the transaction process. It is not easily perceived that the attacker tampers with or replaces the QR code that contains merchant’s beneficiary account. Thus, it is of great urgency to conduct authentication of QR code. In this study, we propose a novel mechanism based on visual cryptography scheme (VCS) and aesthetic QR code, which contains three primary schemes for different concealment levels. The main steps of these schemes are as follows. Firstly, one original QR code is split into two shadows using VC multiple rules; secondly, the two shadows are embedded into the same background image, respectively, and the embedded results are fused with the same carrier QR code, respectively, using XOR mechanism of RS and QR code error correction mechanism. Finally, the two aesthetic QR codes can be stacked precisely and the original QR code is restored according to the defined VCS. Experiments corresponding to three proposed schemes are conducted and demonstrate the feasibility and security of the mobile payment authentication, the significant improvement of the concealment for the shadows in QR code, and the diversity of mobile payment authentication.

This paper aims to explain the nature of quick response (QR) codes and their possible applications in attendance monitoring system at several universities. The aim of this research was to avoid QR code scanning for students who do not attend classes. A QR Code is a two dimensional barcode that is capable of storing a lots of information and various types of information. QR codes have a wide range of uses, including easy storage and transmission of data including web link URLs (Uniform Resource Locators), plain text, email addresses, contact information, SMS or MMS, calendar entries, Wireless network login and more. Based on research and observation, there are many students who like to take a picture of the code and send it to their friends who do not attend the class. There will be an injustice between students attending classes and not attending classes with this problem. Therefore, this research has developed an application of QR code scanner that can scan the QR code whether it is original or copy. In addition, the research has also developed a system of QR code generator and the system will generate the code to become Dynamic QR Code.


Quick Response (QR) Codes are tiny compatible printed pattern on solid surface to transfer a data from a printed medium to a digital medium. The coding information cannot be viewed by the naked eye thus the manipulation of printed pattern is very difficult. In general, QR code is printed in the two-dimension using white and block named QR code modules or data pixels. Static and Dynamic QR codes are available now a days. More than 3000 characters can be encoded over a very tiny space using QR graphics. The data are encoded by QR generator using ISO/IEC 18004:2006. Various types of data can be restored using QR codes and every QR Code contains segment devoted to informing the reader what sort of data it holds and used for coding and decoding the data easily. The most common data types of QR codes are SMS, Email address, phone number, plain text, geo location etc. Nowadays the QR codes are used in various fields. For example, it is used in the marketing and industries to provide the information about the products. In education it is used to register the information about the students in their certificates and to access the information in a website.

<p>Teknologi terbaru yang dapat diterapkan untuk identifikasi yaitu <em>Radio Frequency Identification</em> (RFID) yang merupakan sistem identifikasi tanpa kabel bisa melakukan pengambilan data dengan cepat, mudah tanpa harus bersentuhan dan dapat digunakan untuk operasi otomatis. Sistem RFID terdiri dari tag, pembaca, middleware, aplikasi program dan server. Seiringin perkembangannya muncul juga teknologi pilihan lain yaitu QR Code atau <em>Quick Respon Code</em> dalam mengatasi masalah identifikasi data menjadi efektif dan cepat. Untuk mengakses informasi <em>QR Code</em> berbeda dengan teknologi RFID yang membutuhan perangkat khusus atau <em>reader</em>  sebagai pembaca tag melainkan sangat mudah hanya membutuhkan perangkat camera atau <em>webcam</em> kemudian difokuskan QR Code pada kamera dan akan langsung terbaca dengan cepat. Saat ini dalam mengidentifikasi data medis masih dilakukan secara konvensional yaitu mengetik nomor ID dengan keyboard maka ada kemungkinan terjadi kesalahan dan membutuhkan waktu yang lama sehingga tidak efesien, untuk mengatasi masalah tersebut menggunakan RFID dan QR Code adalah solusi yang tepat, dengan RFID dan QR Code hanya cukup menempelkan pada RFID reader selanjutnya kode akan dilakukan pecarian langsung secara otomatis. Manfaat yang diperoleh pada penelitian ini adalah mengetahui perbandingan RFID dan QR Code melakukan pencarian data medis, dan dapat mengidentifikasi pencarian data medis dengan lebih mudah, cepat dan akurat.</p>


This paper proposed a Quick response code (QR code) based strategy to provide authentication to our digital images. Quick response code is used to provide protection to digital images because of its important characteristics like detection from direction and large data encoding capacity. First of all, Least Significant Bit (LSB) approach is applied on the original image to select LSBs from each block of the image. Next, LSB image is partitioned into sized blocks and mean is calculated for each block of the cell. Then Singular Value Decomposition function is performed on this cell to get singular values which are used as authentication data. After that QR Code generator is used to generate QR code matrix from these singular values. And finally this code is inserted into MSBs to get an authenticated image. Experimental result shows that proposed method produces images with good quality.
