Research on Integrity Verification Algorithms for Outsourced Spatial Data
摘要
Abstract
Outsourced spatial data query services support data owners to outsource their data to location-based cloud service providers and have the cloud service providers process the user's query requests using verifiable data structures.However,since the cloud service provider is not fully trustworthy,it is necessary to verify the services.These schemes usually construct the verifiable data structure locally,yet for spatial data,the user spends a lot of money in constructing the verifiable data structure.For this reason,this paper proposes a data integrity verification scheme based on outsourced spatial queries.This scheme constructs data structures R-tree commonly used in spatial query services in ciphertext by location-based cloud serv-ice providers,which is then used to perform query services and return query results to users who will veri-fy the correctenss of the query results.Finally,security analysis and experimental analysis show the securi-ty and effectiveness of the scheme.关键词
