Synopsis
In data publishing, the data owner delegates the role of satisfying user queries to a third-party publisher. This model is applicable to a wide range of computing platforms, including database caching, content delivery network, edge computing and P2P databases. As the publisher may be untrusted or susceptible to attack, it could produce incorrect query results.
In this work, we introduce a scheme for users to verify that their query results are complete (i.e., no qualifying tuples are omitted) and authentic (i.e., all the result values originated from the owner). The scheme supports range selection on key and non-key attributes, project as well as join queries on relational databases. Moreover, the proposed scheme complies with access control policies, is computationally secure, and can be implemented efficiently. |
