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.

“…Blockchain was successfully integrated with QR in one more study but failed to add additional security on transit [17]. Previous research applied QR code technology in verifying the authenticity of documents using a web application that doesn't require additional installation on the part of the user [18] but failed to consider data security by transmitting data in plaintext and thus is prone to hacking. To address this data security weakness, other studies make use of encryption schemes for security [19]- [21] against hacking.…”

A previous study has been conducted integrating modification on secure hash algorithm 1 (SHA-1) to document integrity verification of printed documents using quick response (QR) codes. However, encryption is warranted as data is transmitted in plaintext directly to the server to prevent hacking and ensuring not only data integrity but data security as well. A more secured document integrity verification using QR code was designed and developed by successfully incorporating a better hashing algorithm– modified SHA-1 and integrating a modern encryption algorithm–modified blowfish algorithm. By integrating both, data integrity and data confidentiality is assured as compared to previous research. The developed software was checked against user requirements to check the acceptability of the software. Error rate and accuracy were also checked to see how the software performed. Based on the testing conducted, it has been found that the document integrity verification software using QR code with the integration of modified SHA-1 hash and Modified Blowfish encryption was acceptable, accurate, and more secure.
