In the rapidly evolving landscape of cloud computing, security remains a paramount concern. This paper explores the transformative potential of integrating blockchain technology and artificial intelligence (AI) to redefine cloud security. Blockchain’s decentralized and immutable ledger provides a robust framework for tamper-proof data storage and transparent transaction records. Coupled with AI’s advanced pattern recognition and real-time anomaly detection capabilities, this integration offers a comprehensive security solution. Key benefits include enhanced data integrity, decentralized data management, and immediate threat response. By leveraging the strengths of both technologies, we propose a novel approach to fortify cloud infrastructures against emerging cyber threats, ensuring a secure and resilient digital environment.
