Fast and Fuzzy Private Set Intersection [article]

Nicholas Kersting
2014 arXiv   pre-print
Private Set Intersection (PSI) is usually implemented as a sequence of encryption rounds between pairs of users, whereas the present work implements PSI in a simpler fashion: each set only needs to be  ...  This is typically orders of magnitude faster than ordinary PSI at the cost of some "fuzziness" in the matching, which may nonetheless be tolerable or even desirable.  ...  Use Cases for Fast PSI Private Set Intersection techniques promise to enjoy a large number of potential applications, but these are made more feasible by a fast protocol such as the one proposed.  ...
