At present, the fast-paced development of big data technology and the Internet of Things has led to the generation of spatiotemporal data streams on a large scale. In this circumstance, data holders often choose the cloud storage of their data to alleviate with the pressure of local storage and computing overhead. However, this is a centralized mode of storage, and the data is susceptible to the risk of tampering and leakage in the absence of physical control over spatio-temporal big data. Therefore, a blockchain-based space-time big data privacy protection scheme is devised in this paper. To begin with, in order to ensure data privacy, the scheme adopts a storage mode in which the public chain are coordinated with the side chain. The former stores various information such as keys and security authentication parameters, while the latter stores private data. Then, the irreversible SHA256 algorithm is applied to authenticate the access nodes. Finally, AES and RSA hybrid encryption is performed to encrypt the collected spatio-temporal big data for the security of private data to be further enhanced. The security performance of the system is evaluated by comparing the success rate of attacks on the blockchain under different circumstances. Also, the system throughput of this scheme is analyzed through simulation, the results of which show that the service life of this system reaches a minimum of 13.79 years when 100 nodes are use. In this context, the system throughput reaches 1607 transactions/s, each node contains 1.2×107 blocks, and the time taken to query specific spatio-temporal data is less than 2 seconds.

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.
