Imagine your pri­va­cy assis­tant is a com­put­er pro­gram that’s run­ning on your smart­phone or your smart­watch. Your pri­va­cy assis­tant lis­tens for pri­va­cy poli­cies that are being broad­cast over a dig­i­tal stream. We are build­ing stan­dard for­mats for these pri­va­cy poli­cies so that all sen­sors will speak the same lan­guage that your per­son­al pri­va­cy assis­tant will be able to understand.
