## Abstract

System and methods are disclosed that enable data sharing across networks, including peer-to-peer sharing of content over wireless networks using peer mobile devices. A database may store content associated with a first peer mobile device. A request from a requester peer mobile device for content associated with a user of the first peer mobile device may be received at a server. The encrypted request is transmitted by the server to the first peer mobile device which may decrypt the request. An authorization token may be transmitted by the first peer mobile device to the server which may then enable the requesting peer mobile device to access the requested content, which may be accessed from the first peer mobile device and/or a cloud storage system.
