Integrity Verification For Outsourced XML Database In Cloud Storage

Database outsourcing has gained significance like the "Application-as-a-Service" model wherein a third party provider has not trusted. The problems related to security and privacy of outsourced XML data are data confidentiality, user privacy/data privacy and finally query assurance. Existing techniques of query assurance involve properties of certain cryptographic primitives in static scenarios. A novel dynamic index structure is called Merkle Hash and B+- Tree. The combination of B+- Tree and Merkle Hash Tree advantages has been proposed in this paper for dynamic outsourced XML databases. The query assurances having the issues are correctness query Completeness and Freshness for the stored XML Database. In addition, the outsourced XML database with integrity verification has been shown to be more efficient and supports updates in cloud paradigms.
