With the rapid expansion of remote sensing technology and cloud computing, vast amounts of remote sensing images are stored and processed in cloud environments. However, ensuring secure, verifiable, and efficient image retrieval remains a significant challenge due to data integrity concerns, unauthorized access, and computational overhead. This paper proposes a blockchain-based secure and verifiable remote sensing image retrieval framework that leverages smart contracts, cryptographic hashing, and distributed ledger technology to enhance security, privacy, and reliability in cloud-based image retrieval. The proposed system integrates a blockchain network to maintain an immutable audit trail, ensuring data integrity and verifiability of retrieval operations. To enhance privacy and efficiency, homomorphic encryption and Merkle tree-based indexing are employed, allowing secure searching without exposing sensitive image data. A hybrid indexing mechanism using content-based and metadata-based retrieval improves accuracy and search performance. Smart contracts enable automated access control and verification, reducing reliance on centralized authorities. Experimental evaluations demonstrate that the proposed framework significantly enhances security, retrieval accuracy, and computational efficiency compared to traditional cloud-based retrieval approaches. The blockchain integration ensures tamper-proof logging of access requests, while the cryptographic techniques safeguard against unauthorized data modifications. The proposed method achieves high retrieval precision, minimal latency, and robust resistance to adversarial attacks, making it a suitable solution for secure remote sensing image retrieval in cloud environments.
