A Survey on Secrete Communication through QR Code Steganography for Military Application

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.

Application of Quick Response Code Indonesian as a Payment Tool in Digitizing MSMEs

The purpose of the research is to contribute to the development of technology in the financial sector, to give influence to the community in terms of cashless, then also to provide insight into financial technology on financial literacy by using QRIS (Quick Response Code Indonesian). MSME use facilitate their business activities by implementing fintech in terms of transaction management and the role of financial technology, is the QRIS (Quick Response Code Indonesian) application as a means of payment. The research method used in the research on the application of QRIS (Quick Response Code Indonesian) as a Payment Tool in digitizing MSMEs is a qualitative descriptive study using field research methods. This study uses interviews with 10 traders and 10 UMKM consumers who use QRIS. The research location is in BSD Modern Market, using non-probability techniques. Primary data taken directly from the object of research. With the direct observation method at the BSD modern market, South Tangerang with interview techniques for both consumers and traders who use QRIS as well as secondary data also obtained through various literatures. The result of the research is that QRIS as a digital payment tool for MSMEs is non-cash digital payment using Gopay, Ovo and others. QRIS has the potential to expand MSME sales, with QRIS an increase in digital sales traffic and a decrease in cash, minimizing the risk of paying counterfeit money, automatically recording transactions, building credit profiles for banks, making it easier to get working capital, payment of retribution, bills, purchasing goods in cash easily.

A Stretchable Strain Sensor Based on CNTs/GR for Human Motion Monitoring

Flexible/stretchable strain sensors have attracted much attention due to their advantages for human-computer interaction, smart wearable and human monitoring. However, there are still great challenges on gaining super durability, quick response, and wide sensing range. This paper provides a simple process to obtain a sensor which is based on graphene (GR)/carbon nanotubes (CNTs) and Ecoflex hybrid, which demonstrates superb endurance (over 1000 cycles at 100% strain), remarkable sensitivity (strain over 125% sensitivity up to 20) and wide sensing range (175%). All results indicate that it is capable for human movement monitoring, such as finger and knee bending and pulse beat. Most importantly, it can be used as a warning function for the night cyclist’s ride. This research provides the feasibility of using this sensor for practical applications.

Anti-Counterfeit Product System Using Blockchain Technology

Fake Products is a serious issue, as in today’s world we can’t really distinguish between real and fake product. And some people make these fake products just to make some profit without thinking about its impact on user and also affects company’s name, profit and sales. Blockchain technology can be used to detect whether the product is real or fake and assure user about the authenticity of the product. Blockchain is a trending technology and lot of applications are using this technology. Blockchain technology is the technology where information is stored in the form of blocks in many databases which is connected with the chains and it doesn’t require any third-party users for permission. Benefits of blockchain is that it is immutable and secure. It is decentralized and distributed. We can use Quick Response [1] (QR) code or an encrypted unique code which is a very efficient technique to detect fake product. When the QR code is scanned or the unique code in entered, it will redirect us to the blockchain containing the information of the product and provides us the details of the manufacturer and information of owner to make decision easy for buyer if they are looking to buy the product.

PENGARUH MEDIA SOSIAL TERHADAP PENGETAHUAN TENTANG QUICK RESPONSE CODE INDONESIAN STANDARD (QRIS)

Quick Response Code Indonesian Standard atau QRIS telah menjadi sarana baru dalam bertransaksi secara online. Namun edukasi terhadap masyarakat dalam menggunakan QRIS masih sangat minim. Akibatnya masyarakat kebanyakan memperoleh pengetahuan tentang QRIS lebih banyak dari sumber tidak resmi seperti media sosial. Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh media sosial terhadap pengetahuan tentang QRIS yang diperoleh mahasiswa di peguruan timggi. Penelitian ini menggunakan metode survey dengan sampel mahasiswa Fakultas Ekonomi dan Bisnis Islam Universitas Islam Negeri (UIN) Datokarama Palu. Hasil penelitian ini menunjukkan baha media sosial berpengaruh secara signifikan terhadap pemerolehan pengetahuan tentang QRIS. Hal ini dinyatakan berdasarkan hasil uji SPSS 21 dengan nilai Fhitung sebesar 109.066 > Ftabel 3,95, dan nilai signifikansi (Sig) ,000 < 0,05 dengan nilai dapat disimpulkan bahwa secara simultan variable Media sosial (X) berpengaruh signifikan terhadap Pengetahuan tentang QRIS (Y). Dengan demikian madia sosial telah menjadi sarana yang efektif dalam pemerolehan pengetahuan baru seperti QRIS.

An Automatic Heuristic Design Approach for Seru Scheduling Problem with Resource Conflicts

In current environments, production systems need the ability of quick response to face the volatile markets. Seru production systems, as a new mode of the production system, have the advantages of quick response, high flexibility, and high efficiency. Seru scheduling, which refers to constructing serus with an exact sequence in limited workspace, is an important decision problem in the operational management of seru production systems and can reflect the reconfiguration nature of seru production systems. This study investigates a seru scheduling problem with resource conflicts, whose objective is to minimize the makespan. An automatic heuristic design approach that combines a genetic programming algorithm and structure similarity-based operators is proposed. Comparative experiments are conducted with human-made rules, basic genetic programming, genetic programming-based algorithm, and with some state-of-the-art scheduling algorithms. The results show the effectiveness and efficiency of the proposed algorithm.

MOBILE WALLETS AND CONSUMER SPENDING IN SINGAPORE: AGARWAL et al. REVISITED

Agarwal et al. ( 2019 ). Mobile wallet and entrepreneurial growth. AEA Papers and Proceedings, 109, 48–53 analyze the impact of the introduction of quick response (QR) codes for mobile payments in Singapore. They find that this not only resulted in a significant increase in the use of mobile wallets, but that there was also a positive spillover effect on debit and credit card payments — in particular at small and new businesses. This note argues that the increase in card sales cannot have been driven by the QR code technology. I also proffer an alternative explanation, namely, that Agarwal et al. simply capture the concurrent increase in popularity of contactless cards.
