Lack of security measures for cybersecurity threat is somewhat vulnerable and can even put one’s digital life at high risk of phishing attack which is so alarming nowadays. Perpetrators may even use fictitious personal information to infiltrate various institutions for their malicious acts. It is the aim of this paper to present a security measure for a safe data transfer by means of vaccination card. Vaccination information is one of the most commonly acquired pieces of data today. However, because most internet data collection processes lack encryption, personal data becomes very vulnerable to threats. As a result, the researchers presented a Centralized Covid-19 Record System, which illustrates secure data transfer via RSA-generated QR codes. A descriptive research design was employed in which a survey questionnaire together with secondary data sources and online tools i.e., RSA Express Encryption/Decryption Calculator and QR code generator were utilized as data instruments. Through a culmination of knowledge on asymmetric cryptography, RSA algorithm, QR codes, and web system development, answers to the founded research questions were unveiled. The web system’s architecture comprises several components and sub-components building its digital makeup. For the system development process, the most essential structural components are the web browser, web server, and database server. Through a message encryption/decryption feature that makes use of the RSA algorithm in generating a key pair, cryptography was implemented in the system. The essential mathematical parameters comprising such features are RSA encryption algorithm, RSA decryption algorithm, and Euler phi function. As for the system development environment, several hardware and software requirements that build and support the system’s end-to-end process were also specified. Upon the employment of those specifications, the system was able to offer several security features including the 15-digit account user IDs and QR code scanning for log-in, secured acquisition of public and private keys, and an admin verification process. Lastly, it was found that asymmetric cryptosystem provides a secured channel for data transfer due to the computational difficulty of factoring the large integers that constitute modulo . Upon the strategic culmination of the study’s framework, well-established system architecture, required system specifications, and security measures, the researchers were able to successfully develop VacciFied.net, a Centralized Covid-19 Record System involving authenticated data transfer process.

“…However, some evidence suggests that it is difficult to read the QR code by increasing the complexity of the recognition of images that are enlarged, although research is required to confirm the output findings [11]. An additional method used to store more data in less space than the QR code adopted zip compression of data by replacing a small code word with a different type of character through a secure multiplex [12]. Other researchers focused on increasing and expanding the amount of stored data by using a multicolour QR code, which was used in market cash registers that scanned the QR code for payment [13].…”

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.

“…Umaria and G.B. Jethava [15,16] focus on the multiplexing technology to represent multiple data bits with new codeword, by combining data compression and multiplexing techniques, they improve the data capacity and security of QR code, while it is more likely to lead to rejection and substitution error in the process of decoding, moreover, the time complexity of compression and demultiplexing of data algorithm still remains to be optimized in the following steps. Ramalho et al propose luminescent QR code based on a polymethylmethacrylate substrate coated with organicinorganic hybrid materials doped with trivalent terbium (Tb 3+ ) and europium (Eu 3+ ) ions, demonstrating the increase of storage capacity per unit area by a factor of two by using the color multiplexing compared with traditional QR code [17] , however, this method simply changes the physical organization rather than encoding structure of QR code, which could be easily damaged by external forces.…”
