Anonymize AML Investigation Files for Oversight and Training – CCPA/HIPAA-compliant de-identification per 31 USC §5318
AML investigation files compiled under an institution's BSA AML program at 31 USC §5318 document the alert trigger, transaction analysis, subject research, and disposition decision for individual investigations. anonym.legal pseudonymizes subject and account identifiers in these files so compliance oversight teams and trainers can evaluate investigation quality and typology coverage without exposing the subject's personal data.
When this applies
Use this workflow when AML investigation files are reviewed by second-line compliance oversight, BSA auditors, or training facilitators who need to assess the analytical methodology, red-flag coverage, and disposition rationale without accessing the identities of the subjects under review.
How anonym.legal handles it
- Upload the AML investigation file — including alert summary, transaction analysis, subject research notes, and disposition record — to anonym.legal.
- The engine identifies the subject's name, account numbers, date of birth, address, SSN, and any named transaction counterparties or associated persons.
- Each individual in the file receives a distinct, consistent pseudonym applied across the alert summary, investigation narrative, and disposition record.
- Alert trigger parameters, transaction amounts and categories, red-flag indicators, and the disposition decision are preserved in plain text.
- A reversible mapping table is encrypted and stored with US data residency.
- Export the pseudonymized investigation file for oversight review, audit, or training use.
- Retain the original investigation file in your BSA recordkeeping system for the applicable five-year retention period.
What you provide
- AML alert summary and trigger documentation
- Transaction analysis and subject research notes
- Disposition decision record and any SAR referral documentation
Limitations & cautions
- Pseudonymized investigation files must not be used as a substitute for the original file in any regulatory or law enforcement production.
- Where an investigation results in a SAR filing, the SAR must be processed separately under the SAR workflow; the SAR itself may not be pseudonymized for regulatory submission.
- The tool does not assess whether the investigation methodology meets the analytical standards expected by FinCEN or your primary federal regulator.
- Investigation files that include embedded screenshots from transaction monitoring systems may require manual review of image-embedded text.
FAQ
Can I pseudonymize AML files that resulted in SAR filings to use as training case studies?
Yes. Files from completed investigations — including those that resulted in SAR filings — can be pseudonymized for training purposes. The SAR itself must remain on file unchanged, but the investigation file can be pseudonymized separately for training use.
Are transaction counterparty names pseudonymized alongside the primary subject?
Yes. Named transaction counterparties who are natural persons receive distinct pseudonyms. Corporate counterparty names are preserved unless you flag them for pseudonymization.
How are multi-subject investigations handled?
Each named subject receives a distinct pseudonym applied consistently throughout the investigation file. The relationship between subjects — such as co-account holders or transaction counterparties — is preserved in the pseudonymized structure.
