  • Patent number: 11394542
    Abstract: Embodiments disclosed herein are related to the deauthorization of a private key associated with a decentralized identifier. While a user of a computing system is authenticated as a decentralized identifier, the system detects user input, and determines based on that user input that the private key associated with the decentralized identity is to be revoked. In response to this determination, the private key is deauthorized so that the private key cannot be used to perform actions for the decentralized identity at least until the private key is restored.

  • Patent number: 11386225
    Abstract: Embodiments disclosed herein are related to computing systems and methods for localizing how a user will receive and view received DID-related data. The computing system and methods are implemented in the decentralized network that implements a distributed ledger that backs one or more decentralized identities (DID) for one or more users of the computing system. Various sets of rule are accessed. The sets of rules specify how a DID owner will receive and view DID-related data received from a third party entity. The sets of rules are applied to the DID-related data received from the third party entity. The received DID-related data is modified such that the received DID-related data conforms to the one or more sets of rules. The modified DID-related data is provided to the DID owner so that the DID owner is able to view the modified DID-related data according to the applied sets of rules.

  • Patent number: 11363032
    Abstract: The resolving of a decentralized identifier at a customized security level. When a decentralized identity is resolved, it is resolved into a data structure (e.g., a document) that corresponds to the decentralized identity. The resolving includes causing a user interface to be rendered to the user, detecting user interaction with the user interface, and then based on that user interaction identifying a level of resolver security to use when resolving that decentralized identifier. The method then resolve the decentralized identity using that identifier level of resolver security. As an example, higher levels of resolver security may be obtained by using consensus from multiple resolvers.

  • Publication number: 20220164267
    Abstract: A computing system is configured to receive user data from a user associated with a decentralized identifier (DID) and authenticate the user based on the DID via data recorded on a distributed ledger. In response to authenticating the user, the computing system stores the user data redundantly at each of a plurality of decentralized identity stores. One of the plurality of decentralized identity stores is designated as a primary decentralized identity store. In particular, redundantly storing the user data includes storing the user data at the primary decentralized identity store, and causing each remaining decentralized identity store in the plurality of decentralized identity stores to store the user data following the primary decentralized identity store.

  • Patent number: 11329968
    Abstract: Permitting a decentralized identity to authenticate on behalf of a centralized identity to a centralized identity system, and/or permitting a centralized identity to authenticate on behalf of a decentralized identity to a decentralized identity system. Thus, the principles described herein permit authentication across decentralized and centralized domains. The identity system receives and registers a delegation for the first identity to authentic as the second identity, where one of the identities is a decentralized identity and one is a centralized identity. Thereafter, when the identity system receives a communication from the first identity to access a resource owned by the second identity, the identity system accesses the registration to determine that the first identity is authorized to authenticate as the second identity, authenticates the first identity as the second identity, and grants the first identity access to the resource owned by the second identity.

  • Patent number: 11288389
    Abstract: Embodiments disclosed herein are related to computing systems and methods for a DID owner to select a permission scope for sharing DID-associated data. A set of permission scopes are accessed for DID-associated data. The DID-associated data is associated with a DID of a DID owner. The set of permission scopes define entities whom are to be given access to the DID-associated data by the DID owner. The DID owner is prompted to select a specific permission scope of the set of permission scopes for one or more of the DID-associated data. The selected permission scope is applied to the one or more of DID-associated data. The selected permission scope defines the specific entities that are to be given access to the one or more of the DID-associated data.

  • Patent number: 11249870
    Abstract: Failover between decentralized identity stores in the context of there being multiple decentralized identity stores that are each under the control of a single decentralized identity to store data belonging to or regarding the decentralized identity. Third parties can use the decentralized identity to at least conditionally access the data of the primary decentralized identity store. However, in response to detecting a failover event, one of the remaining decentralized identity stores is promoted as the new primary decentralized identity store. As part of this promotion, the new primary decentralized identity store replaces the old primary decentralized identity store as being the decentralized identity store that is accessed using the decentralized identity.

  • Patent number: 11251977
    Abstract: Use of a validation data structure in order to securely communicate an encrypted claim that has a decentralized identifier as a subject. The sending system generates the validation data structure and presents the validation data structure to a user that owns the decentralized identifier. The sending system encrypts the claim using at least the validation data structure, and constructs a message that includes the encrypted claim, but which does not include the validation data structure. The relying party receives the message. However, without separately receiving the validation data structure from the user, the relying party computing system cannot decrypt the encrypted claim. If the user wishes the relying party computing system to have access to the claim, the user may communicate the validation data structure to the relying party computing system.

  • Patent number: 11245524
    Abstract: Using an association data structure corresponding to a derived decentralized identifier of a subject entity to share a verified claim about the subject entity to one or more relying entities. A decentralized identifier of a subject entity is derived from a source decentralized identity of the subject entity. Next, an association data structure is created using the derived decentralized identifier. The association data structure is structured to be interpretable by a relying entity as demonstrating that a verified claim is about the derived decentralized identity. The relying entity is then caused to be provided the verified claim about the subject entity. The verified claim includes the association data structure that was created using the derived decentralized identifier.

  • Patent number: 11238170
    Abstract: Delegating a scope of permission between pairwise DIDs. First, a computing system determines a relationship between the first DID and a second DID. The first DID and the second DID are pairwise DIDs. Based on the relationship, the computing system delegates a scope of permission owned by the first DID to the second DID. In particular, the computing system defines the scope of permission, grants a public key of the second DID the scope of the permission. The delegation of the defined scope of permission is signed by a private key of the first DID, such that the signature is a proof of the delegation. A portion of data related to the delegation is then propagated onto the distributed ledger.

  • Patent number: 11240244
    Abstract: Embodiments disclosed herein are related to computing systems and methods for providing a presentation interrupt for a DID attestation. A DID attestation is accessed that is issued by a first entity of a decentralized network. The DID attestation defines information that has been generated by the first entity about a DID owner who is the subject of the DID attestation. The DID attestation includes interrupt metadata that directs that the first entity be contacted prior to the DID owner being able to present the DID attestation to a second entity of the decentralized network. In response to the DID owner attempting to present the DID attestation to the second entity, the first entity is contacted as directed by the interrupt metadata. Authorization information is received from the first entity. The authorization information indicates if the DID owner is able to present the DID attestation to the second entity.

  • Patent number: 11190512
    Abstract: An attestation component to make attestations about itself to a relying party. The attestation component offers identity attestations of a particular decentralized identity, and manages use of a private key of that decentralized identity. However, the attestation component also has its own private key that is different than the private key of the decentralized identity for which it offers attestations. As an example, the attestation component might, using its own private key, provide an integrity attestation from which an integrity with which the attestation component has managed the private key of the decentralized identity may be determined. Based on this integrity attestation, a relying party can determine whether to trust other attestations provided by the attestation component on behalf of the decentralized identity.
