The proposed methods are highly secure (relying on well-studied cryptographic encryption and hashing primitives), accurate (comparable to conventional searching systems designed for unencrypted data), and efficient (in terms of computational complexity and communication bandwidth).
The invention has a wide range of applications in numerous fields that would require or benefit from privacy-preserving search and multiple clearance/access levels. This includes, but is not limited to, out-sourcing data storage to 3rd party service provider, data management in government and intelligent operations, enabling scholarly study of sensitive data, facilitating document discovery process in litigation. Overall, the invention forms a primary building block to facilitate various knowledge discovery tasks for which security and privacy is a major requirement.
