摘要:Authenticated multistep NN search required for applications that require a proof of result correctness. Clients issue similarity queries to a provider. The latter returns the result set and additional verification information, based on which the client establishes that the result is indeed correct, i.e., it contains exactly the records of DB that satisfy the query conditions, and that these records indeed originate from their legitimate data source . A similar situation occurs for data replication, i.e., when a data owner stores DB at several servers. Clients issue their queries to the closest server, but they wish to be assured that the result is the same as if the queries were sent to the original source of DB. Notarization services have been proposed to safeguard against tampering in document databases.
