With blockchain or not? Opportunities and challenges of self-sovereign identity implementation in public administration

National Digital Identity: Current Landscape, Emerging Technologies and Future Directions

“…This has been highlighted in recent studies (Mentasti, 2022;Udwan et al, 2020;Rim, 2022). Initially, most NDI systems were based on usernames and passwords, but as security threats have increased, the use of biometrics and other advanced technologies has become prevalent (Mahula et al, 2021). For example, facial recognition, fingerprints and iris scans are used in some NDI systems to verify identity.…”

“…In Germany, the identity card offers a digital signature that verifies the authenticity of electronic documents, reducing fraudulent activity (Sobczak, 2013). Itsme in Belgium offers two-factor authentication, ensuring that only authorised people can access their personal accounts (Mahula et al, 2021).…”

“…The field of NDI is evolving rapidly, and new technologies such as blockchain and biometrics are playing an important role in shaping the future of these systems. Blockchain technology, for example, could provide a secure and decentralised platform for storing and sharing personal information, making NDI systems more transparent, efficient and resilient to cyberattacks (Mahula et al, 2021). Biometric authentication, on the other hand, could improve the accuracy and convenience of identity verification by using features such as fingerprints, facial recognition or iris scans.…”

“…Itsme uses a combination of biometric and PIN-based authentication, with strong encryption and privacy protections. However, there have been some concerns around the usability of the system, particularly for older or less tech-savvy users (Mahula et al, 2021) https://psc.egov.bg/e n/psc-electronicidentification…”

Disruptive Technologies for e-Diasporas: Blockchain, DAOs, Data Cooperatives, Metaverse, and ChatGPT

“…However, traditional remittance systems can be slow, expensive, and susceptible to fraud (Naik & Jenkins, 2020). Blockchain technology can address these issues by providing a more secure, efficient, and cost-effective way to transfer money in developing countries of the Global South (Calzada, 2023b;Hughes et al, 2019;Mahula et al, 2021;Zook, 2023). In the next methodological and comparative section, these cases will be included in the analysis (see Table 1): Blockchain for Humanity, Bitnation, BABB, Tari, AidCoin, World Identity Network, Humaniq, and Golem Network.…”
