Central Concerns and Questions
We are interested in developing mechanisms for users to verify that their query results are complete (i.e., no qualifying values are omitted) and authentic (i.e., all the values in the query results originated from a trusted owner).
Emerging Ideas and Initiatives
The number of successful attacks on the Internet shows that it is very difficult to guarantee the security of online search engines. A breached server that is not detected in time may return incorrect results to the users. To prevent that, we need a methodology for generating an integrity proof for each search result.
