“…The only way to save the travel industry is to cooperate with the government and all travel industries to create a safe and comfortable travel space. Vaccine passports are used as a tool of travel (Lee et al, 2022), so safety policies must be followed by each industry. For example, airlines, hotels, restaurants, etc., must secure social distance between customers and customers for a more comfortable trip, strive for cleanliness and disinfection, and provide customers with information about nearby hospitals and public health centers.…”

Vaccine Passport and Traveler Behaviors in the New Market of the Domestic and International Tourism Industry Facing the With-Corona Era

et al. 2022

To ensure a smooth and rapid recovery of tourism, countries around the world are stepping up vaccinations against COVID-19. China, in particular has a very high vaccination rate due to its own vaccine production. Following this trend, many countries have started introducing vaccine passports as an alternative solution to verify valid and vaccinated travelers. This study attempted to understand the fundamental perceptions of travelers’ intentions using vaccine passports. A total of 601 samples were investigated and analyzed. As a result, four factors were identified: perceived usefulness, destination trust, risk perception, and perception of incentives. Also, this study performed means comparisons analysis with the major demographic characteristics of respondents. Based on this study, it is expected that the results will contribute to the revival of the travel industry in the future and provide valuable implications for marketing plans to help the travel industry suffer from COVID-19.

“…Thirteen articles [181][182][183][184][185][186][187][188][189][190][191][192][193] applied blockchain, mHealth, algorithms, and biometric technologies for COVID-19 vaccination certification. Eight of these studies were considered innovative, but some digital solutions had technical barriers, transaction costs, and ethical barriers to promotion.…”

Applications of Social Media and Digital Technologies in COVID-19 Vaccination: Scoping Review

et al. 2023

View full text Add to dashboard Cite

Background Social media and digital technologies have played essential roles in disseminating information and promoting vaccination during the COVID-19 pandemic. There is a need to summarize the applications and analytical techniques of social media and digital technologies in monitoring vaccine attitudes and administering COVID-19 vaccines. Objective We aimed to synthesize the global evidence on the applications of social media and digital technologies in COVID-19 vaccination and to explore their avenues to promote COVID-19 vaccination. Methods We searched 6 databases (PubMed, Scopus, Web of Science, Embase, EBSCO, and IEEE Xplore) for English-language articles from December 2019 to August 2022. The search terms covered keywords relating to social media, digital technology, and COVID-19 vaccines. Articles were included if they provided original descriptions of applications of social media or digital health technologies/solutions in COVID-19 vaccination. Conference abstracts, editorials, letters, commentaries, correspondence articles, study protocols, and reviews were excluded. A modified version of the Appraisal Tool for Cross-Sectional Studies (AXIS tool) was used to evaluate the quality of social media–related studies. The review was undertaken with the guidance of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Results A total of 178 articles were included in our review, including 114 social media articles and 64 digital technology articles. Social media has been applied for sentiment/emotion analysis, topic analysis, behavioral analysis, dissemination and engagement analysis, and information quality analysis around COVID-19 vaccination. Of these, sentiment analysis and topic analysis were the most common, with social media data being primarily analyzed by lexicon-based and machine learning techniques. The accuracy and reliability of information on social media can seriously affect public attitudes toward COVID-19 vaccines, and misinformation often leads to vaccine hesitancy. Digital technologies have been applied to determine the COVID-19 vaccination strategy, predict the vaccination process, optimize vaccine distribution and delivery, provide safe and transparent vaccination certificates, and perform postvaccination surveillance. The applied digital technologies included algorithms, blockchain, mobile health, the Internet of Things, and other technologies, although with some barriers to their popularization. Conclusions The applications of social media and digital technologies in addressing COVID-19 vaccination–related issues represent an irreversible trend. Attention should be paid to the ethical issues and health inequities arising from the digital divide while applying and promoting these technologies.

“…In blockchain application situations, the identity authentication approach resolves the seeming contradiction between the need for anonymity and the need for traceability [39]. The fundamental purpose of Lee's work [40] is to design a vaccination passport (VP) validation system that is based on a wide blockchain architecture and is intended for utilization in a simulated international scenario. [41] Propose a secure authentication approach for users that utilizes the advantages and characteristics provided by blockchain technology and smart contracts.…”

There is currently a growing concern about the preservation of individual privacy, particularly in the context of the increasing usage of Big Data technologies, such as the Data Middle Platform. As such, the question of how to enhance privacy and security has become a primary concern in today's world of Industry 4.0. In this article, we review related literature on the security and privacy challenges of the Data Middle Platform, and explore the use of Blockchain and zero-knowledge proof theories for authentication. We propose an algorithm that combines k-anonymity, homomorphic encryption, blockchain, and zero-knowledge proof for traceable authentication technology, and demonstrate its feasibility in the laboratory. Our experimental results verify the efficacy of the algorithm. As the algorithm is intended for industrial use, we compare and discuss it with existing authentication techniques in the penultimate section. Finally, we conclude our work and highlight directions for future research.
