要旨:
A longstanding open problem is that of how to get high quality statistics
through direct queries to databases containing information about individuals
without revealing information specific to those individuals. Diffix is a new
framework for anonymous database query that adds noise based on the filter
conditions in the query. A previous paper described Diffix for a simplified
query semantics. This paper extends that description to include a wide variety
of common features found in SQL. It describes attacks associated with various
features, and the anonymization steps used to defend against those attacks.
This paper describes the version of Diffix used for bounty program sponsored by
Aircloak starting December 2017.
