RT Journal Article T1 A Blockchain-Based Audit Trail Mechanism: Design and Implementation: Design and implementation A1 Regueiro, Cristina A1 Seco, Iñaki A1 Gutiérrez-Agüero, Iván A1 Urquizu, Borja A1 Mansell, Jason AB 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.
