Certifying Data from Multiple Sources
Abstract Data integrity can be problematic when integrating and organizing information from many sources. In this paper we describe efficient mechanisms that enable a group of data owners to contribute data sets to an untrusted third-party publisher, who then answers users’ queries. Each owner gets a proof from the publisher that his data is properly represented, and each user gets a proof that the answer given to them is correct. This allows owners to be confident that their data is being properly represented and for users to be confident they are getting correct answers. We show that a group of data owners can efficiently certify that an untrusted third party publisher has computed the correct digest of the owners’ collected data sets. Users can then verify that the answers they get from the publisher are the same as a fully trusted publisher would provide, or detect if they are not. The results presented support selection and range queries on multi-attribute data sets and are ...
