Abstract
A first entity having a first set of tagged data and a second entity having a second set of tagged data share data that is selected based on a set of common tags present in both the first and second sets of tagged data. The set of common tags is determined using a private set intersection protocol that, in many examples, preserves the privacy of the two entities. In an embodiment, each entity identifies a set of data objects associated with the set of common tags, and another private set intersection protocol is performed to identify a set of common data objects available to both entities. Each entity provides, to the other entity, those data objects associated with the set of common tags that are not in the set of common data objects available to both entities thereby providing a matching set of data objects to both entities.
