Block Chain-Assisted Verifiable And Secure Remote Sensing Image Retrieval In Cloud Environment

Remote sensing image retrieval in cloud environments presents significant security and verifiability challenges due to the risks of unauthorized access, data tampering, and privacy breaches.To address these issues, this study proposes a blockchain-assisted framework for secure and verifiable image retrieval.Blockchain technology ensures data integrity and transparency by maintaining an immutable and decentralized ledger, enhancing trust among multiple stakeholders.The proposed approach integrates cryptographic techniques and smart contracts to enable efficient authentication and secure query execution while preserving user privacy.Experimental evaluations demonstrate that the framework effectively enhances security, retrieval accuracy, and system efficiency compared to traditional cloud-based methods.This solution is particularly beneficial for applications requiring high-assurance remote sensing data, such as environmental monitoring, disaster management, and defense operations.
