Aml_Transaction_Anomalies (Synthetic B2B Dataset Preview)

Add me on Discord: xomohappy for access support, delivery questions, or product questions about this premade commercial dataset.

This is a premium, privacy-compliant, industry-safe synthetic dataset simulating Anti-Money Laundering (AML) suspicious logs for B2B applications.

About this Dataset

This dataset is generated programmatically using large language models combined with a strict data curation and validation layer.

Privacy-safe: Contains synthetic names, phone numbers, and company identifiers.
Structured and verified: Schema-validated, formatted, and deduplicated to reduce model overfitting risk.
Target AI use case: FinTech compliance teams and fraud detection developers.
Category: Finance

Schema Definition

Each record contains the following fields:

transaction_id (str): Pre-assigned Transaction ID (e.g. TXN-AML-XXXX)
account_holder (str): Pre-assigned Account Holder Name
account_type (str): Personal Savings, Corporate Checking, or Trust Account
transaction_pattern (str): Description of transaction amounts, frequencies, and locations
compliance_flag (str): Suspicious Activity Report (SAR) Flag, Enhanced Due Diligence (EDD), or Cleared
investigator_rationale (str): Detailed analysis of layering, structuring, or velocity indicators

Buyer Assurance

This dataset was checked with deterministic local tooling before publication. The audit verifies schema consistency, uniqueness, text depth, duplicate risk, repeated wording, domain terminology coverage, and obvious PII leakage patterns.

All rows receive schema and content checks. Cross-record similarity uses a bounded sample of pairs to keep generation fast; it does not establish that every possible pair is dissimilar. The score measures these automated checks, not downstream model performance or independent medical, legal, or regulatory validation.

Findings

No blocking quality findings detected.

Data SHA-256: 75e29f20d3807e3e1509b6c8f5c9e781332a4730b6ef1df20488d5d48e7ec6f5. Re-audited on 2026-10-08.

Repair: defective fictional narratives were corrected; record IDs and synthetic profile identities were retained. Legacy previews now cover all six scenario classes.
