SECURE AND TRANSPARENT CLOUD TASK SCHEDULING USING BLOCKCHAIN TECHNOLOGY

Abstract

Cloud computing has revolutionized data storage and computational processes, but it still faces challenges in secure task scheduling and data integrity. Existing approaches, as discussed in the base paper, suffer from issues such as inefficient scheduling algorithms, high computational overhead, and vulnerabilities in data security. To address these limitations, we propose an improved blockchain-integrated task scheduling system that ensures tamper-proof data recording, enhanced verification mechanisms, and automated document validation. Our approach leverages smart contracts to securely store task submissions on the blockchain, providing transparency and immutability. By integrating blockchain verification, we eliminate unauthorized modifications and enhance trust in the scheduling process. Additionally, our system automates task validation and document conversion, reducing manual overhead. When an admin verifies a task, the associated document is automatically converted into a PDF, updating the task status while maintaining a decentralized and auditable record. Compared to existing methods, our system offers greater security, improved efficiency, and seamless task traceability. Through this novel blockchain-based framework, we successfully mitigate the drawbacks highlighted in the base paper, enhancing the security and reliability of task scheduling in cloud environments.
