Evidence Chain

Audit-ready evidence

MASAMUNE does not treat evidence as a PDF-only output. It ties connected drive state, operator context, execution history, report generation, and QR verification into one explainable chain.

01 Device handling

Capture device target, method, and result at the operational starting point.

02 Runtime log

Keep operator, timestamp, and connection state in the same record.

03 PDF certificate

Turn execution history into a submission-ready report.

04 QR / cloud verification

Keep later review and authenticity checks inside the same chain.

The structure keeps device handling, report output, QR verification, and cloud reference points inside one evidence chain.

What holds the evidence chain together

Runtime logsKeep who ran what, when it ran, and which device was processed.

Submission-ready proofFormat the evidence into PDF output that works for customer or audit handoff.

Authenticity checksUse QR verification and cloud reference points for later re-checks.

Key Capabilities

Erasure Log Recording

Automatic upload for every erase operation, including model, serial, IMEI, method, and outcome.

Certificate Issuance

Auto-generated PDF certificates with digital signatures, QR verification, and NIST-aligned metadata.

Worker Management

Track which operator performed each erase and keep accountability attached to the evidence set.

Data Export

Export logs as CSV or Excel for audit, internal reporting, or downstream systems.

Tamper-resistant Design

Keep report output and runtime context tied together so the authenticity story stays intact.

Real-time Monitoring

Watch worker progress live and catch exceptions before they become evidence gaps.

Want to see the evidence flow first?

We can walk through certificate output, QR verification, and cloud log context as one operational story.
