Comments Off on Toward Secure Multikeyword Top-k Retrieval over Encrypted Cloud Data
Posted in: Final year projects
Abstract Cloud computing has emerging as a promising pattern for data outsourcing and high-quality data services. However, concerns of sensitive information on cloud potentially causes privacy problems. Data encryption protects data security to some extent, but at the cost of compromised efficiency. Searchable symmetric encryption (SSE) allows retrieval of encrypted data over cloud. In this […]

Comments Off on A Novel Privacy Preserving Location-Based Service Protocol With Secret Circular Shift for -NN Search
Posted in: Final year projects
Abstract Location-based service (LBS) is booming up in recent years with the rapid growth of mobile devices and the emerging of cloud computing paradigm. Among the challenges to establish LBS, the user privacy issue becomes the most important concern. A successful privacy-preserving LBS must be secure and provide accurate query [e.g., -nearest neighbor (NN)] results. […]
