Abstract: A data provider generates a data encryption key and an identifier, uses the data encryption key to encrypt data, sends the encrypted data and the identifier to a data requestor, and sends the data encryption key and the identifier to a crypto information server. The data requestor sends the identifier to the crypto information server to request the encryption key. The crypto information server authenticates the data requestor and, contingent on that authentication, sends the data encryption key to the data requestor. If a plurality of data instances are captured, then for each instance, a respective data encryption key and identifier are generated.

Abstract: A system for forwarding packed-based media in a network, the system comprising: a) at least one forwarder, configured to extract at least one packet of media from at least one media source accessible to the forwarder, and to forward the extracted packet of media to at least one capture device, and b) a forwarding manager, communicating with the forwarder, using a predefined protocol, the communicating comprising receiving media accessibility information relating to the forwarder and the at least one media source accessible to the forwarder and receiving a request identifying a media source, and configured to list at least one of the forwarders, wherein the listed forwarders are usable for forwarding the at least one packet of media from the identified media source according to the media accessibility information.
