Abstract:
1. A method comprising: receiving at a controller computing device a request to transfer digital content from a first computing device to a second computing device; receiving at the controller computing device a key/hash pair from a third computing source; sending from the controller computing device an encryption key based on the key/hash pair to the first computing device for encrypting the digital content; the controller computing device authorizing the transfer of the digital content from the first computing device to the second computing device; receiving at the controller computing device from the second computing device a result of a hash function performed on the digital content at the second computing device; the controller computing device comparing the key/hash pair provided by the third computing device to the result of the hash function received at the controller computing device; sending to the second computing device, in response to comparing that the result of the hash function corresponds to the key/hash pair from the controller, a decryption key for decrypting the digital content at the second computing device.
