Abstract
Systems and methods are disclosed with which queries can be sent to various clients of a trusted query network in a trusted query network message. In one embodiment, each registered client receives the message and determines whether or not it will participate in the query. If so, the client adds to the message in a first data round a true response to the query and obfuscation data, and then forwards the message on to the next client (or back to the client that initiated the query if each client has added its data to the message). In a second round, the message is again sent to each participating client, which this time removes its obfuscation data. Once each client has removed its obfuscation data, a final result is obtained that can be sent to each of the clients.
