To ensure the authenticity of information during the process of tracing the source of safety incidents, several key measures can be implemented:
Data Integrity Verification: Use cryptographic hashing (e.g., SHA-256) to verify that data has not been tampered with during collection, transmission, or storage. For example, log files from servers can be hashed and compared at different stages to confirm their integrity.
Chain of Custody Tracking: Maintain a detailed record of who accessed or modified the data, when, and how. This ensures accountability and prevents unauthorized alterations. Tools like digital signatures and audit logs can help track this chain.
Trusted Data Sources: Rely on information from verified and secure sources, such as authenticated devices, secure APIs, or trusted third-party monitoring systems. For instance, security information and event management (SIEM) systems can aggregate logs from validated endpoints.
Blockchain for Immutable Records: In some cases, blockchain technology can be used to store critical incident data in an immutable ledger, ensuring that records cannot be altered retroactively.
Automated Validation: Implement automated scripts or AI-driven tools to cross-check data against known patterns or baselines, flagging anomalies that may indicate tampering or inaccuracies.
For cloud-based solutions, Tencent Cloud offers services like Cloud Audit (CAM) for tracking user activity and changes, Tencent Cloud Blockchain for secure data recording, and Tencent Cloud Log Service (CLS) for centralized log management with integrity checks. These tools help ensure the authenticity of information during safety incident investigations.
