“…The QR code can be scanned by aiming the device's camera at it and making sure the whole code is inside the frame that appears on the screen. When the code is successfully scanned, it is identified and opened in a specific application, such as a web browser (Türker, 2022;Fu & Liu, 2019). A novel enhanced security method for QR code-based document identification was developed in 2016 (Revathi, Annapandi & Ramya, 2013).…”

In the modern world, people frequently fabricate their credentials in order to secure a job or to show up where and when it is necessary. Verification is the most effective approach to identify those fraudulent certificates. Despite this, the paper verification method requires a drawn-out and time-consuming process to handle certificate verification because the certificates must be returned to the institutions who awarded them. As a result, the certificates either fail to pass verification or are delayed by the lengthy process. Hence, a certificate verification method using QR codes is developed in this study for quick verification of University of Cross River State (UNICROSS) certificate genuineness. A Smartphone and 3D Printed QR Code were employed for the enhancement of UNICROSS certificate mobile authentication services. ScanTrust anti-counterfeiting services were used to secure and host the encrypted information. Results show that our framework is effective for creating mobile authentication services with high user satisfaction rate and having reasonably low computing requirements.

In Visual Cryptography Schemes (VCSs), for message n transparencies are generated, such that the original message is visible if any k of them are stacked. VCS especially for large values of k and n, the pixel expansion’s reduction and enhancement of the recovered images’ display quality continue to be critical issues. In addition to this, it is challenging to develop a practical and systematic approach to threshold VCSs. An optimization-based pixel-expansion-free threshold VCSs approach has been proposed for binary secret images’ encryption. Along with contrast, blackness is also treated as a performance metric for assessing the recovered images’ display quality. An ideally secure technique for a secret image’s protection through its partition into shadow images (known as shadows) is the Visual Secret Sharing (VSS) scheme. Acquirement of a smaller shadow size or a higher contrast is the VSS schemes’ latest focus. The white pixels’ frequency has been utilized to demonstrate the recovered image’s contrast in this work. While the Probabilistic VSS (ProbVSS) scheme is non-expansible, it can also be readily deployed depending upon the traditional VSS scheme. Initially, this work has defined the problem as a mathematical optimization model such that, while contingent on blackness and density-balance constraints, there is the maximization of the recovered images’ contrast. Afterward, an algorithm dependent on the Tabu Search (TS) is devised in this work for this problem’s resolution. Multiple complicated combinatorial problems have been successfully resolved with the powerful TS algorithm. Moreover, this work has attempted to bolster the contrast through the density-balance constraint’s slight relaxation. Compared to the older techniques, the proposed optimization-based approach is superior regarding the recovered images’ display quality and the pixel expansion factor from the experimental outcomes.

“…Another study emphasized the importance of two levels of security and how building information was used in the QR code by improving the information on privacy levels and lightweight accounts, which affect the rest in turn. Such approaches, however, have failed to address encoded decryption processes because a limitation of this work is the use of Base 64, which is restricted to representing 64 characters [9]. The main purpose of this research effort is to improve the data storage of QR codes.…”

This paper provides a novel method to improve the data storage of a quick response code (QR code) by applying encrypted lossless compression technology. QR codes are used in several domains, particularly when there is a need to transfer various types of text information. A key aspect of this work is to thus propose a new methodology to overcome the weaknesses of the limited size of the traditional QR code, which has long been an important issue in a wide range of areas. The proposed algorithm incorporates a clear and simple plan for overcoming this difficulty by inserting confidential information into a QR code message. The QR code is updated through the addition of levels that help to share secure messages of various sizes and to authenticate documents for verification and validation. In this work, the newly proposed QR code does not reconstruct the configuration or structure of the QR code. Rather, it provides better security because it relies on the features of the Huffman compression algorithm to reduce the size of the input data and the principles of encryption through the XOR function, which is done through a variable encryption key. The experimental results show the superiority of our method over the previous methods. The scope of this endeavour is thus wide, and there is potential for the encoding of different types of data with a high compression rate in the near future. INDEX TERMS 1D barcode, quick response code (QR code), Huffman coding, security.
