Distributed ledger technology and European Union General Data Protection Regulation compliance in a flexible working context

Abstract

Compliance of distributed ledger technology (DLT) based solutions with the European Union General Data Protection Regulation (EU GDPR) is currently a hot topic both from a technical point of view, as well as from a legal and normative one. Flexible working is a new working model where employees can perform their work activity without specific time and space constraints. In this context privacy and information trustworthiness are relevant and, therefore, on the one hand it can gain benefit from using DLT based solutions, on the other hand it must comply with the GDPR. This paper describes a solution that combines DLTs and the new Ciphertext‐Policy Attribute Based Encryption cryptographic techniques to support compliance with the EU GDPR in the context of flexible working. The devised solution is being concretely experimented, in the context of the EU H2020 CITADEL project, by the Municipality of Bari (Italy).

Implementing GDPR-Compliant Surveys Using Blockchain

“…This section presents an overview of other projects that use blockchain-based systems to store sensitive information complying with GDPR and compares the solutions found in the literature and our proposal to support surveys. Some projects already use blockchain to store personal data and comply with GDPR [9,40], but most are meant to solve a specific problem for a specific domain.…”

“…Rotondi et al [40] used DLT to store data concerning work activity. The project stored workers' information as well as the work hours of each employee.…”

A systematic literature review on sensitive data protection in blockchain applications

“…right of access by the data subject, right of erasure and rectification of data, right of restricted processing, individual decision-making and profiling and lastly right to know data portability. 46 Larger risks involved in working with financial blockchain as it is highly volatile in nature. 38,47 The problem of private key management is still not solved in blockchain applications.…”

Data Encryption Algorithm Aes by Using Blockchain Technology: A Review

“…By utiliz ing block chain, data protection can be produced (Costa et al, 2019;Pitchay et al, 2015;Sivakumar et al, 2019). Then, many people who are not responsible is difficult to interfere (Tawalbeh et al, 2015;Rotondi et al, 2019). There are many encryption methods often used to secure data (Shimbre & Deshpande, 2015;Sivakumar et al, 2019), such as: RSA, LEAP, AES, and so on (Alharby, Aldweesh, & Moorsel, 2018;Yassein et al, 2017;Tawalbeh & Saldamli, 2019).…”
