Introducing Financial Data Generation: Ledgers + Fraud + PCI

The "Random Number" Problem

Most synthetic data tools treat financial transactions like random numbers. They generate a transfer of $500, but fail to deduct that $500 from the source account. The result?

❌ Balance Sheet Mismatch: Assets != Liabilities + Equity

You can't test a banking ledger, a trading platform, or an accounting system with broken math. You need constraint-safe financial generation.

Introducing Aphelion Financial

We've built the first synthetic data engine that understands Double-Entry Bookkeeping.

📒 Immutable Ledgers

Every debit has a matching credit. Running balances are guaranteed correct.

🕵️ Fraud Patterns

6 distinct attack vectors for training ML models.

🔒 PCI-DSS Ready

Luhn-valid CС numbers, tokenization, masked PANs.

⚖️ Regulatory Audit

SOX-compliant audit trails for every modification.

Deep Dive: The Generators

1. Double-Entry Ledger Generator

Our LedgerGenerator maintains state. When it generates a transaction, it updates the running balance of the involved accounts in memory before writing to the database.

// Guaranteed to sum to zero
{
"debit": { "acct": "account_a", "amount": 100.00 },
"credit": { "acct": "account_b", "amount": 100.00 }
}

2. ML-Ready Fraud Detection

Training fraud models on clean data is useless. Aphelion injects specific fraud patterns:

Velocity Attacks: Multiple small charges in seconds.
Geographic Jumps: Transaction in Location A followed by one in Location B 5 mins later.
Structuring: Amounts just below reporting thresholds ($9,999).
First-Party Fraud: Chargebacks on legitimate history.

3. Compliance & Security

We generate data that looks like it's already been secured. Perfect for staging environments where real PII is a liability.

Tokenization: Replaces PANs with consistent tokens.
Hashing: SHA-256 for passwords and sensitve strings.
Audit Logs: Who changed what, when, and—crucially—why.

Use Cases

Fintech Startups

Launch your MVP with populated dashboards. Show investors a "live" app with 10,000 transactions, not an empty state.

Legacy Migration

Testing a migration from Mainframe to Cloud? Generate identical datasets in both schemas and verify the ledger logic holds up.

Fraud Ops Training

Train your manual review team on spotting synthetic identities and subtle velocity patterns.
