Patent ID: 8842835

Claim:
A consuming device which is part of a network including other devices, the device comprising: computer processing machinery to: receive encrypted content and a plurality of doubly encrypted secret shares from a content provider, the doubly encrypted secret shares being received from the content provider doubly encrypted by an inner encryption and then an outer encryption such that the outer encryption needs to be decrypted before the inner encryption, the outer encryption being uniquely encrypted for decryption by a corresponding one of the other devices in the network, the inner encryption being for decryption only by the consuming device; distribute the doubly encrypted secret shares from the consuming device to the other devices, the consuming device being forced to distribute the secret shares to the other devices for decryption before the secrets can be used; a content storage medium to store the encrypted content therein, wherein the computer processing machinery is also operative to: receive, by the consuming device from the other devices, at least some of the secret shares with the outer decryption decrypted; decrypt the inner encryption of the received at least some secret shares; form a content decryption input from the decrypted at least some secret shares; receive the encrypted content from the content storage medium; receive the content decryption input; and decrypt the encrypted content using the content decryption input thereby rendering decrypted content; and a content consumer to use the decrypted content.
