Abstract
A data transfer process can include multiple verification features usable by a “source” device to ensure that a “destination” device is authorized to receive a requested data object. The source device and destination device can communicate via a first communication channel (which can be on a wide-area network) to exchange public keys, then use the public keys to verify their identities and establish a secure session on a second communication channel (which can be a local channel). The data object can be transferred via the secure session. Prior to sending the data object, the source device can perform secondary verification operations (in addition to the key exchange) to confirm the identity of the second device and/or the locality of the connection on the second communication channel.
