Fig. 6 shows an example of QR code symbol. The figure is version 1 (type 2) and the module is 21 X 21 cells, vertical 21 cells and horizontal 21 cells. This version is specified from 1 to 40, increased by 4 cells per one version up. The maximum version is 40 and the size is 177 X 177 modules. Fig. 6 is a case of the QR code version 1 modules that are arranged in a grid pattern of black and white squares. In this QR code symbol [11][12][13], there are three position detection patterns (Finder patterns) in the upper left corner, bottom left and top right corner. Then the timing pattern is placed between every one of these position detection patterns. Additionally, alignment patterns are introduced in the version 7 or higher. Then Table I shows the main specifications of the QR code. There are four modes available, (1) number mode, (2) alphanumeric mode, (3) 8 bit byte mode and (4) kanji and kana characters ...

The modern technologies and applications compatible working with various operating systems increase the accuracy of completion and quick access, and as a result of the increasing reliance on Wi-Fi networks and the use of mobile phones and their applications and the spread of e-learning with the tendency to e-books on a large scale, This paper focused on developing a system that generates a unique QR code containing information and an identifier number for each electronic book within E-library system based on a customized database. The system will automatically generate a unique QR code for each book, that includes brief information about the book and its ID number, this QR code can be scanned by any scanner application and identify the book's information quickly and easily, noting that the QR scanning process can be done without the need for the mobile device (scanner by camera) to be connected to the Internet.
... The main features of QR code contain large capacity, small printout size, high-speed scanning, advanced error correcting and freedom direction scanning (Sanz-Valero et al. 2013;Zugang and Nagurney 2013;Tarjan et al. 2014). It also brings the benefits of simple traceability in WSN without introducing excessive control overheads and can inquire the detailed information from the mobile phone easily (Abdelhak et al. 2011;Kaushik 2011;Jian-Ping et al. 2012). ...
As one of the widely consumed foods, aquatic products are prone to spoilage and deteriorate in the cold chain. It is very important and necessary to trace and track the aquatic products' quality and safety in the cold chain. This paper aims to develop a quality and safety traceability system integrated with wireless sensor network ( WSN ) and quick response ( QR ) code ( SMS‐CQ ) for aquatic products. This paper analyzed temperature fluctuations of aquatic products in cold‐chain logistics that is implemented and evaluated in an actual cold chain. The results show that compared with the traditional system, SMS‐CQ is an effective quality management tool that leads to real‐time monitoring and tracing of the aquatic products in the cold chain: WSN technology enables SMS‐CQ to automatically realize the real‐time temperature acquisition, wireless remote transmission and monitoring; QR code provides valid means for the QR code generation, error correction and static and sensed dynamic information inquiry.
Practical Applications
The proposed method could be extended by future researchers or practitioners for future work in many wide areas in cold‐chain monitoring and traceability applications.
... Active attacks include masquerade, replay, modification of messages, and denial of service [11,12].Therefore, security threats (such as eavesdropping, data modification, phishing, website leaks etc.) force us to develop new methods to counter them. Considering QR barcodes as an effective media of sharing information, many researchers have proposed information/data hiding methods [6,7, 8, 9.] as well as online transaction systems [1,2,3,4,5] using QR barcode. In this paper, we describe different information hiding schemes using QR barcode. ...
Nowadays, the information processing system plays crucial part in the internet. Online
information security has become the top priority in all sectors. Failing to provide online
information security may cause loss of critical information or someone may use or distribute
such information for malicious purpose. Recently QR barcodes have been used as an effective
way to securely share information. This paper presents the survey on information hiding
techniques which can share high security information over network using QR barcode.

The E-Commerce market has grown rapidly in recent years with the increasing popularity of the Internet. As authentication and reliability play important and demanding roles in various Information Processing Systems, the key area On-Line Transaction Systems are generally considered to be attack prone and become more susceptible to direct attacks and abuse than their offline counterparts. In the current scenario, the Secure Electronic Transaction System (SETS) is used as one of the main E-Commerce applications to process the electronic transaction securely and safely via the Internet. Due to drastically increasing malicious activities, SETS requires fiddly approaches to be introduced. This insecurity of transaction puts a big challenge in terms of transaction protection. This paper aims to work on the aforementioned challenge, therefore, an approach is introduced which works to secure the critical information shared during the On-Line Transaction Processing (OLTP) over on the insecure channel.
This paper deals with the indoor localization using Wi-Fi networks. It reacts to the increasing trend in smart devices containing a large number of sensors and modules. The work deals with the use of a Wi-Fi module and a camera. The Android application which uses these modules for the localization and acquisition of fingerprints of wireless networks was created. The application consists of a client and a server side. The approach suggested enables a mobile device to be localized in a building for which a database with fingerprints of wireless networks is created. The application suggested can be used for every building provided that the following conditions are fulfilled; QR codes or other unique visual tags are distributed, the map of the building is available and the fingerprints of wireless networks are captured.
The grow of smart phone and mobile devices market, has created a new set of opportunities for companies to develop new publicity strategies. One of the most widespread forms of engaging mobile users from printed materials is based on the use of QR codes, which have been adopted for many different applications such as accessing web sites or downloading premium content. In this research work, we will be performing embedding QR code into color image and hiding information using QR code, in order to make them visually appealing to the user while maintaining acceptable decoding robustness. In contrast to previous approaches the methods presented here allows to automatically embedding QR codes into color, grayscale or binary images. These embedding are designed to be compatible with standard decoding applications and can be applied to any color image with full area coverage. The embedding problem is solved by the integration of halftoning method. Finally, we show experimental results of halftoning of color image, embedded QR code image in color image and decoded QR code image from color image.
Quick response (QR) codes provide a rapid, easy, convenient, accurate, and automatic data collection method. With the increasing application and popularization of wireless communication and mobile device technology, two-dimensional barcode technologies have been employed for production, logistics, and sales. To apply the benefits of technology to the medical field, for this study, we used various applications of QR code in a hospital medical equipment repair management system. The main goal was to enable equipment or facility engineers to rapidly obtain detailed equipment information and return the medical equipment to normal operations. The experiment results indicate that method developed in this study can significantly improve the efficiency of medical equipment repairs, ensure engineers receive the correct information, shorten the Web site process time, and highlight the significance of solving such problems. The research in its actual state will be full support tool for the repair of medical equipment management. The results of both tests allow stating that from the point of view of efficiency and saving cost, the new system is fast and economical, making it highly competitive with exiting repair management system.
