SecurePay AI: HardwareAccelerated Payment Tokenize

Overview SecurePay AI eliminates merchant credit card liabilities by replacing raw card numbers with single-use, merchant-locked tokens. Existing AI fraud prevention agents are too slow (5-10s) for real-time checkout pages. We solve this with a dual-path hybrid architecture running on AMD hardware. How it Works (Key Features) Local ML Fast-Path: A local XGBoost classifier evaluates low-risk micro-transactions (<500 PKR) locally in less than 1 millisecond at zero cloud token cost. Explainable AI Reasoner: High-value or suspicious checkouts are routed to DeepSeek V4 Pro on AMD Instinct MI300X GPUs (via Fireworks AI) for reasoning-based risk checks. Envelope Encryption: Cards are secured using AES-256-GCM under a versioned Key Encryption Key (KEK) derived via PBKDF2-HMAC-SHA256, allowing instant rotation on our dashboard. Cryptographic WORM Ledger: All transactions are written to a Write-Once-Read-Many ledger secured by SHA-256 hash chains to ensure tamper-proof logs. Stateful Circuit Breaker: The system automatically falls back to local XGBoost if the remote API experiences latency spikes or timeouts. 3DS2 TouchID UI: Suspicious checkouts trigger a frictionless, inline WebAuthn TouchID fingerprint challenge directly in the portal.
