This posting continues the theme of blockchain (or distributed ledger) and digital rights management understood broadly. Assigned to Cambridge Blockchain, LLC, the first of this week's Spotlight Patents addresses techniques for managing digital identities. Assigned to Manifold Technology, the second patent addresses techniques for providing a cryptographic platform for exchanging information.
9,749,140, "Systems and methods for managing digital identities," assigned to Cambridge Blockteam, LLC
Systems and methods for managing digital identities. In some embodiments, a method is provided, comprising acts of: using a plurality of measurements taken from a user to generate an identifier for the user, the identifier comprising a cryptographic proof of the plurality of measurements; instantiating a digital identity representation associated with the identifier for the user, the digital identity representation comprising program code that implements rules for attestation; generating an electronic signature over the digital identity representation; and publishing the digital identity representation and the electronic signature to a distributed ledger system.
9,397,985, "System and method for providing a cryptographic platform for exchanging information," assigned to Manifold Technology, Inc.
A system and method configured for providing a cryptographic platform for exchanging information. One or more information transactions including encrypted information may be generated and/or provided to a distributed ledger. The one or more information transactions may include information intended for one or more parties. Information transactions intended for one or more parties may be identified. An information transaction may include one or more of a transaction identifier associated with one or more parties, an information payload, and/or other information. The information payload may include encrypted information. The encrypted information may be encrypted with one or more public keys associated with one or more parties. One or more information transactions may be retrieved from the distributed ledger. The encrypted information may be decrypted with one or more private keys that correspond to the public keys. Presentation of the encrypted information to one or more parties may be facilitated.
