Blockchains (smart contracts, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Applications. Assigned to Ericsson (SE), the first application discloses techniques for managing cloud services using smart contracts and blockchains in a federation of cloud providers. Assgined to Tenet 3, LLC, the second application discloses blockchain records with third party digital signatures as a trust element for high-risk digital content.

A first data center receives a request, from a tenant, to access a first service. Responsive to determining that the tenant is not associated with a delegation contract, the first data center records a delegation contract for the tenant. A second data center receives a request, from the tenant, to access a second service, where the second data center is physically separate from the first data center. Responsive to determining that the tenant is associated with the delegation contract recorded in the blockchain database, the second data center causes an update of the delegation contract in the blockchain database; causes the second service to provide access to the tenant; transmits, to the tenant, a confirmation that the second service can be accessed, and transmits an update to the first data center indicating that the delegation contract has been updated to include a second service offer.

A permissioned blockchain, using off-chain storage, provides advantages over blockchains that rely on consensus and/or store information within the blockchain. Advantages include enhanced viability, compactness, and the ability to register material with distribution limitations (e.g., military classified). Examples create an immutable public record of data signatures that confirm when data is intact, without distributing the data itself, so that widespread availability of the blockchain (beyond those privileged to see the data) advantageously increases the size of the community that is able to detect spoofing or forgery attempts. A permissioning entity limits submissions to manage blockchain growth, foreclosing problematic material that may risk long-term viability. Examples render blockchain operations resistant to advanced persistent threats (APTs), leverage digital signatures as additional trust elements for high-risk data, link records to track pedigree and enable identification of superseded (obsolete) data, and leverage out-of-band date proof to enable independent verification of integrity and no-later-than data-of-existence.
