title = "Interactive compression to external information",

abstract = "We describe a new way of compressing two-party communication protocols to get protocols with potentially smaller communication. We show that every communication protocol that communicates C bits and reveals I bits of information about the participants{\textquoteright} private inputs to an observer that watches the communication, can be simulated by a new protocol that communicates at most pol (I) · log log(C) bits. Our result is tight up to polynomial factors, as it matches the recent work separating communication complexity from external information cost.",
