Semantic-Based Compound Keyword Search Over Encrypted Cloud Data
Abstract
Introduction
Semantic-Based Compound Keyword Search Over Encrypted Cloud Data In cloud computing, an excessive number of personal or business users outsource their data to cloud storage to enjoy the benefits of “pay-on-demand” services and high computing execution. Users choose to encrypt the data before outsourcing to preserve privacy. Thus, the traditional keyword search can not be executed directly on the encrypted data, which restricts the use of data. Semantic-based keyword search is not only convenient for users, but it also expresses exactly the intentions of users.

Conclusion
To extract the semantic information of keywords accurately, we first propose an ontology-based compound concept semantic similarity calculation method (CCSS), which greatly improves the precision of sameness measurement between compound concepts by taking into account compound characteristics and a variety of sources of information in ontology. Low overhead on computation and search accuracy outperforming current schemes.
