An Implementation and Evaluation of Blockchain-based Digital Health Passports

While several electronic apps help with contact tracing of COVID patients, and those apps do not prevent patients from getting in contact with healthy international travelers or audiences attending large gatherings. Medical tests are getting expensive, and individuals may falsify their test results when traveling. This paper aims to implement and evaluate a secure Digital Health Passport (DHP) using blockchain technology. Users (issuers, holders, verifiers) register in BigchainDB to create or view digital health certificates. The issuer has read-write access to upload test results and read-only access to holders and verifiers to guarantee tamper-free. The holders can share the test results using QR codes to verifiers. In this implementation, This research study use BigchainDB as the blockchain database. Then, DHP is evaluated based on the smart healthcare requirements and the key features of blockchain technology. The evaluation and discussions present that the DHP is secured, immutable and traceable. DHP use cases will be helpful as health identification cards in international tourism, attending nationwide events, workplaces and educational institutions, and the entertainment industry. © 2022 IEEE.

Implications of Digital Citizenship in Social Media to build a safe environment in the Covid-19 situation

The great technological convergence, which has emerged in recent years due to the appropriation of the globalized world and the emergence of the Covid-19 pandemic, leads us to formulate various approaches and questions, in relation to the digital identity of the users on the internet and on how to forge a global and secure digital citizenship. New media based on digital technologies such as social media, are generating a daily activity both as means of communication, interaction, and especially today as educational environments, this is leading to the formation of a digital society. This global phenomenon responds to a research study raised in university-level students from the city of Arequipa, this had as a pilot institution for the research process the Catholic University of Santa Mariá. Under the survey proposal, the implications related to social interaction in social media were determined;based on these results, some proposals were made to build safe environments for interaction in this time of pandemic and for subsequent years. It was concluded that it is essential to be able to generate and disseminate protocols and social norms to students for digital environments and social media, to establish safe environments for interaction and navigation. © 2021 IEEE.
