Immutable ledger method and apparatus for managing the distribution of content
A system comprising a plurality of peer caches associated with a corresponding plurality of content owners; shared ledger logic having a channel for each content owner of a plurality of content owners, the shared ledger logic to maintain a shared ledger data structure and to perform the operations of: in response to receipt of a first content title, responsively recording a first ledger entry for the first content title which is visible to a first content owner which owns the first content title; receiving an encryption key from the content owner, wherein the first content title comprises an encrypted content title encrypted with the key; storing the encrypted content title on one or more network storage devices; and when the encrypted content title reaches an edge cache, using the key to decrypt the encrypted content title and updating the first ledger entry to identify the edge cache.
1. A system comprising:
an electronic device to distribute content titles of one or more content owners; and
a ledger fabric to maintain a data structure and to perform:
establishing a channel for a first content owner of the one or more content owners;
recording an entry in the data structure upon receipt of a content title owned by the first content owner, the entry visible to the first content owner, wherein the entry in the data structure comprises a first field to indicate an encryption key; and
encrypting the content title using the encryption key,
wherein the encrypted content title is transmitted to an edge cache, the edge cache using the encryption key to decrypt the encrypted content title, the decryption causing an update of the entry in the data structure to identify the edge cache.
2. The system of claim 1 , wherein the entry in the data structure comprises a second field to indicate a source network component from which the content title was received.
3. The system of claim 1 , wherein the entry in the data structure comprises a third field to indicate a time at which the content title was received.
4. The system of claim 1 , wherein the entry is to be updated in response to any copies made and/or decryption of the content title.
5. The system of claim 1 , wherein the encryption key is received from the first content owner.
6. The system of claim 1 , wherein the first content owner identifies the edge cache as containing the content title based on the entry in the data structure, the first content owner issues a transaction to purge the content title from the edge cache.
7. The system of claim 1 , wherein the entry in the data structure includes a key that is a cryptographic hash of a previous entry in the data structure.
8. The system of claim 1 , wherein the channel for the first content owner includes the electronic device and the edge cache as endpoints, and an intermediate device storing the encrypted content title between the endpoints.
9. The system of claim 1 , wherein the entry comprises a block in a blockchain, the block comprising a timestamp and transaction data.
10. A method comprising:
distributing, though an electronic device, content titles of one or more content owners; and
maintaining a data structure on behalf of the one or more content owners by performing:
establishing a channel for a first content owner of the one or more content owners;
recording an entry in the data structure upon receipt of a content title owned by the first content owner, the entry visible to the first content owner, wherein the entry in the data structure comprises a first field to indicate an encryption key; and
encrypting the content title using the encryption key,
wherein the encrypted content title is transmitted to an edge cache, the edge cache using the encryption key to decrypt the encrypted content title, the decryption causing an update of the entry in the data structure to identify the edge cache.
11. The method of claim 10 , wherein the entry is to be updated in response to any copies made and/or decryption of the content title.
12. The method of claim 10 , wherein the first content owner identifies the edge cache as containing the content title based on the entry in the data structure, the first content owner issues a transaction to purge the content title from the edge cache.
13. The method of claim 10 , wherein the entry in the data structure includes a key that is a cryptographic hash of a previous entry in the data structure.
14. The method of claim 10 , wherein the channel for the first content owner includes the electronic device and the edge cache as endpoints, and an intermediate device storing the encrypted content title between the endpoints.
15. A non-transitory machine-readable medium having program code stored thereon which, when executed by a machine causes the machine to perform:
distributing, though an electronic device, content titles of one or more content owners; and
maintaining a data structure on behalf of the one or more content owners by performing:
establishing a channel for a first content owner of the one or more content owners;
recording an entry in the data structure upon receipt of a content title owned by the first content owner, the entry visible to the first content owner, wherein the entry in the data structure comprises a first field to indicate an encryption key; and
encrypting the content title using the encryption key,
wherein the encrypted content title is transmitted to an edge cache, the edge cache using the encryption key to decrypt the encrypted content title, the decryption causing an update of the entry in the data structure to identify the edge cache.
16. The non-transitory machine-readable medium of claim 15 , wherein the entry in the data structure comprises a second field to indicate a source network component from which the content title was received.
17. The non-transitory machine-readable medium of claim 15 , wherein the entry in the data structure comprises a third field to indicate a time at which the content title was received.
18. The non-transitory machine-readable medium of claim 15 , wherein the entry comprises a block in a blockchain, the block comprising a timestamp and transaction data.
