ProofBridge Liner

Hardened Safety Kernel for Property Collateral Risk in South African Banking

ProofBridge Liner is a production-grade probabilistic trust infrastructure designed to safeguard banking collateral against fraud in property transfers. Built on a Bayesian Beta-Binomial model running inside an AMD MI300X Trusted Execution Environment (TEE), it provides real-time risk scoring with hardware-attested integrity and automated forensic evidence preservation for regulatory compliance.

🚀 Key Features

• —Hardware-Enforced Trust: AMD MI300X TEE with PCR0 attestation for tamper-proof scoring
• —Bayesian Risk Stratification: Separates administrative noise from structural fraud using gamma-adjusted thresholds
• —Regulatory Automation: FSCA JS2, FICA SAR, Cybercrimes Act compliance with automated reporting and forensic evidence bundling
• —Zero-Cost Efficiency: AMD GPU acceleration with Puter.js integration (no API keys required)
• —Resilient Operations: Stdout fallback auditing, input guards, and disaster recovery protocols
• —Forensic Preservation: Hardware-attested evidence chains for SAPS prosecution under Cybercrimes Act

📊 Compliance Status

• —✅ FSCA Joint Standard 2 of 2024: HIGH (Automated) - Continuous assurance with incident reporting and hardware-attested evidence
• —✅ FICA / FIC Amendment Act: HIGH (Automated) - goAML-compliant SAR generation with automated XML export
• —✅ Cybercrimes Act 19 of 2020: FORENSIC GRADE - SHA-512 hashed evidence bundles with TEE binding
• —✅ POPIA: COMPLIANT - PII sanitization with non-PII audit logs and consent management
