Cloud ULT BLADDER CONTROL storage enables users to obtain cheap online storage services on demand through network connection anytime and anywhere.However,due to the untrustability of cloud service providers,third-party institutions and users as well as the inevitable malicious attacks,there are many security vulnerabilities of cloud storage.Blockchain has the potential to build a trusted platform with its characteristics of decentralization,persistence,anonymity and auditability.Therefore,the research on cloud storage security mechanism based on blockchain technology has become a research trend.Based on this,the security architecture of cloud sto-rage system and the security of blockchain technology are first outlined,then the literature review and comparative analysis are conducted from four RAW ORG ALMOND BUTTER SMOOTH aspects of access control,integrity verification,data deduplication and data provenance.

Finally,the technical challenges of blockchain-based cloud storage security mechanism are analyzed,summarized and prospected.
