Blockchains (smart contracts, distributed ledgers) and rights management broadly construed are the themes of today's Spotlight Applications. Assigned to Inveniam, the first application discloses techniques for digital contracts in blockchain environments. Assigned to Supefile, the second application discloses techniques for remote ownership and content control of media files on untrusted systems.

Digital or "smart" contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a contract identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.

One example method includes receiving, by a client computing device, a request to open a superfile stored in a memory device at the client computing device, the superfile comprising encrypted content, the request comprising user credential information; in response to receiving the request to open the superfile, communicating, by the client computing device, a request to a remote server to access the superfile, the request including a credential associated with the user account; receiving, from the remote server, cryptographic information; decrypting, using the cryptographic information, the encrypted content; accessing and presenting the decrypted content; and maintaining communications with the remote server while the decrypted content is accessed.
