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.

“…Recently, Barros et al [16] proposed a privacy-preserving vaccination pass solution based on a self-sovereign identity concept with decentralized identifiers, VCs, zeroknowledge proofs, and blockchain. Their implemented prototype uses the Sovrin blockchain; Hyperledger Indy; JavaScript-based websites; Aries agents; Near-Field Communication (NFC) and Quick Response (QR) codes for local transfer of data; and digital wallet (connect.me) that is capable of managing VCs.…”

The recent COVID-19 pandemic situation highlights the importance of digital vaccine certificates. In response, the European Union (EU) developed EU Digital Vaccine Certificates to enable proof of non-infectivity and completed vaccinations. However, these solutions suffer from several shortcomings, such as ineffective certificate holder identification and a high violation of user privacy with the disclosure of sensitive information. In this work, we present a novel solution for privacy-preserving EU Digital Vaccine Certificates. Our solution solves the aforementioned privacy and security shortcomings and is in line with current EU legislation, i.e., the General Data Protection Regulation (GDPR), the upcoming revision of the electronic IDentification, Authentication, and trust Services (eIDAS), called regulation eIDAS 2.0, and the new tools that it envisages to be led by European digital identity. This identity is intended to allow citizens to prove their identity to access online services, share digital documents, or simply prove specific personal characteristics such as age without revealing their identity or other personal information. The core of our proposal is built on our novel attribute-based credential scheme, which can be easily implemented on various handheld devices, especially on Android smartphones and smartwatches. However, due to the lightweight nature of our scheme, it can also be implemented on constrained devices such as smart cards. In order to demonstrate the security, privacy, and practicality inherent in our proposal, we provide the security analysis of the cryptographic core along with a set of experimental results conducted on smartphones and smart cards.

“…At the same time, Zero-knowledge proof features that one can convey the results of private information without telling the detail of the truth to others so that the sender can pre-vent the private information from adversaries ( Wang et al., 2022b ), but this method has to be decided by the designer who will choose the proof way. Therefore, the TA chain chooses to use non-interactive Zero-knowledge proof to solve this problem ( de Vasconcelos Barros et al., 2022 ). The great distinguished figure is that the receiver only needs to tell the sender what information they would like to verify, non-interactive Zero-knowledge proof will choose the best approach to get the results and translate them to the sender.…”
