A Study on Blockchain and Artificial Intelligence Integration for Secure Financial Transactions at HDFC Bank

Vollständiger Abstract

Worum geht es in dieser Arbeit?

This study, titled "A Study on Blockchain and Artificial Intelligence Integration for Secure Financial Transactions at HDFC Bank," evaluates the structural shifts, security improvements, and financial feasibility of integrating distributed ledger technology (blockchain) and machine learning systems (AI) into private commercial banking infrastructures. Digital transactions face rising cyber threat exposures, manual auditing delays, and data breach risks under traditional database structures. This research conducts a 5-year capital budgeting analysis (2021-2025) of an automated cryptographic transaction security platform implemented at HDFC Bank. Project feasibility is evaluated using standard capital budgeting metrics: Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PBP), and Benefit-Cost Ratio (BCR). Quantitative metrics indicate that smart contract audits and AI anomaly models constitute 64% of security CapEx. Integrating AI-optimized blockchain smart contracts reduces transaction settlement latency to 15 seconds, while improving fraud detection accuracy to 99.5% and reducing unauthorized breach events to zero by 2025. The financial model yields a positive NPV of 284.5 Crores and an IRR of 38.6%, indicating strong investment feasibility. The study concludes that the synergistic integration of blockchain and AI is highly viable, offering commercial banks substantial operational cost savings, regulatory compliance, and robust asset protection.
