Licensee MDPI, Basel, Switzerland.Audit logs are a critical component in today’s enterprise business systems as they provide several benefits such as records transparency and integrity and security of sensitive information by creating a layer of evidential support. However, current implementations are vulnerable to attacks on data integrity or availability. This paper presents a Blockchain-based audit trail mechanism that leverages the security features of Blockchain to enable secure and reliable audit trails and to address the aforementioned vulnerabilities. The architecture design and specific implementation are described in detail, resulting in a real prototype of a reliable, secure, and user-friendly audit trail mechanism.13164604enginfo:eu-repo/semantics/openAccessjournal article10.3390/a14120341BlockchainAudit trailReliabilityIntegrityUsabilityMonitorBlockchainAudit trailReliabilityIntegrityUsabilityMonitorTheoretical Computer ScienceNumerical AnalysisComputational Theory and MathematicsComputational MathematicsProject IDinfo:eu-repo/grantAgreement/EC/H2020/872570/EU/An Advanced Circular and Agile Manufacturing Ecosystem based on rapid reconfigurable manufacturing process and individualized consumer preferences/KYKLOS 4.0info:eu-repo/grantAgreement/EC/H2020/872570/EU/An Advanced Circular and Agile Manufacturing Ecosystem based on rapid reconfigurable manufacturing process and individualized consumer preferences/KYKLOS 4.0Funding InfoThis research was funded by the European Commission, grant number 872570 (H2020 KYKLOS 4.0 project).This research was funded by the European Commission, grant number 872570 (H2020 KYKLOS 4.0 project).http://www.scopus.com/inward/record.url?scp=85120322514&partnerID=8YFLogxK
