Voice fraud SAR evidence guide: documenting synthetic media events
FINRA-supervised firms need auditable documentation when voice fraud involves deepfakes. The Sonotheia Voice Fraud SAR Evidence Guide helps compliance officers document synthetic voice events in Suspicious Activity Reports (SARs) with decision-trace evidence aligned to FinCEN and FINRA expectations.
Opaque score numbers do not meet FinCEN's reporting standards. Sonotheia exports structured decision traces so compliance teams can document objective, physics-based anomalies in their filings.
FINRA voice fraud deepfake documentation
FINRA voice fraud deepfake documentation should show what was measured, which thresholds applied, and why escalation was reasonable. Sonotheia evidence packages supply sensor-level logs and calibration version stamps that support supervisory review and SAR narrative preparation without retaining raw audio.
Constructing audit-ready SAR narratives
FinCEN guidance (FIN-2024-DEEPFAKEFRAUD) advises financial firms to document the type of synthetic media and the indicators detected. Sonotheia's evidence packages provide structured JSON logs detailing sensor-level configurations and calibration version numbers suitable for internal recordkeeping.
What we do not claim yet
We do not claim that Sonotheia's evidence traces constitute final legal proof or replace human compliance reviews. The decision to file a Suspicious Activity Report (SAR) rests solely with the reporting institution's compliance officer based on their overall customer due diligence.
Oversight and interagency alignment
The FINRA 2026 Annual Regulatory Oversight Report, the NCUA AI resource, and the FinCEN deepfake media alert (FIN-2024-DEEPFAKEFRAUD) all reinforce the duty of financial firms to establish documented verification chains. Audit trails must show why an escalation was made and what objective measurements supported the alert.

Frequently asked questions
- How should FINRA firms document voice fraud deepfake events for SARs?
- Record the synthetic-media indicators detected, the active calibration version, sensor contributions, and the supervisory rationale for escalation. Sonotheia evidence packages supply those fields so compliance can populate SAR narratives without inventing a reconstruction after the fact.
- What structured data is included in the evidence packages?
- The packages export hashed decision trace JSON records, sensor anomaly scores, active thresholds, calibration metadata, and raw audio cryptographic hashes.
- Does Sonotheia store client PII or biometric files?
- No. The system processes the audio in transient RAM, extracts mathematical metadata, hashes the result, and immediately discards the audio.
- Does Sonotheia file the SAR automatically?
- No. The platform generates the evidence package. Compliance personnel use the structured telemetry to populate their filing workflow.
