National Database Request–Blockchain Audit Security Dataset

The dataset captures real-world national database access activity collected from operational smart-government service infrastructures supporting multi-department digital transactions. It contains 455,603 anonymized access-request records reflecting diverse identity roles, authorization policies, service interactions, and blockchain-anchored audit events. Each record integrates request behavior, session context, network conditions, and permissioned-ledger verification metadata to enable trustworthy misuse detection research. The feature space includes request semantics, identity attributes, operational workload indicators, and blockchain validation signals such as transaction hashes, smart-contract execution outcomes, validator confirmations, and audit timestamps. Security outcomes are labeled into four governance-critical classes: legitimate access, policy violation, insider misuse, and malicious or injection attempts, supporting dependable access monitoring and forensic analytics.
