Integrating Hybrid Blockchain Solutions and Cloud Encryption Techniques for Ensuring the Integrity and Confidentiality of Financial Data within Cloud Infrastructure

Abstract

Background Information: Cloud computing's quick uptake has transformed the administration and storage of financial data by providing scalability and cost effectiveness. Nonetheless, security issues with confidentiality, data integrity, and illegal access continue to exist. For financial data protection, modern security measures like cloud encryption and hybrid blockchain integration are required because traditional encryption methods are insufficient against changing cyberthreats. Objectives: The objectives of this research are to evaluate the security flaws in traditional encryption and storage methods, create a hybrid blockchain framework that combines publicand private blockchains for improved data integrity, apply sophisticated encryption methods like homomorphic and attribute-based encryption to fortify confidentiality, assess how well the suggested security framework mitigates cyberthreats, and improve financial data protection through real-time monitoring and AI-driven threat detection. Methods: Public and private blockchains are combined with encryption methods like cryptographic hashing and homomorphic encryption in a hybrid security framework. Machine learning improves threat detection, while smart contracts guarantee transaction integrity. Open Metaverse blockchain datasets are used to evaluate performance, including security resilience, encryption efficiency, and latency. Empirical results: Results shows 40% increase in security resilience and a 30% decrease in latency. The hybrid model outperforms blockchain and standalone encryption techniques with an accuracy of 95.5%. Blockchain maintains data integrity while encryption techniques improve confidentiality, offering cloud-based financial transactions the best possible balance between security and efficiency. Conclusion: Cloud encryption and hybrid blockchain combine to improve integrity, confidentiality, and threat resistance, strengthening cloud infrastructures against online attacks and guaranteeing safe financial data management.
