Abstract
A method and system for retrieving data from devices in a way that seeks to preserve privacy and ensure the integrity of the retrieved data is provided. A retrieval system is implemented on a network of devices that communicate with each other via a secure communications link. Each device is directly connected to one or more 'friend' devices that it trusts. The retrieval system operates by forwarding a request for data from one friend device to another friend device. Each friend device may optionally add data to the request until all the requested data is added. The request with the retrieved data is returned to the device that initiated the request.
