Digital identity information associated with the item, such as ownership information, history, properties, and the like, may be located on one or more networks. An entity, after authenticating itself and/or the item, may use the identifier to locate, retrieve, and/or update the item's digital identity information on the network.

Abstract: Techniques for a server-based association of a device with a user account are described. In an example, a computer system receives, from a second device, first data of a first device. The first data indicates a request for a first association between the first device and a user account. The computer system determines that the first data is valid based on second data associated with the first device. Based on the first data being valid, the computer system sends, to the second device, third data to initiate a user authentication. The computer system then receives, from the second device, a user identifier based on the user authentication and determines that a second association between the user identifier and the user account already exists. The computer system causes the first association between the first device and the user account to be generated based on the second association.

Abstract: In embodiments, an authentication server interfaces between a user device with a self-signed certificate and a verifying computer that accepts a user name and password. The user device generates a self-signed certificate signed by a private key on the user device. The self-signed certificate is transmitted to a verifying party computer over a network. The verifying party stores the self-signed certificate with user identification data, including at least one of a user name, user address, user email, user phone number, user tax ID, user social security number and user financial account number. In subsequent communications, the verifying party receives a certificate chain including the self-signed certificate, and matches that with the user identification data stored in a database.

Abstract: A proxy revocation service provides a reliable service for performing revocation checks. The proxy revocation service queries public certificate authorities for the revocation status of a set of digital certificates and maintains a database of the revocation statuses. The proxy revocation service provides a singular endpoint that is Application Protocol Interface (API) accessible to web clients. Web clients communicate with the proxy revocation service through use of API message to perform revocation checks, rather than communicating with the public certificate authorities using an online certificate status protocol (OCSP). Use of the proxy revocation service provides both a reliable service for performing revocation checks as well as shifts the complexity away from the web clients.

Abstract: As a default, a global permissions model is established. The global permissions model serves for applying a first set of resource access permissions to shared content objects. Additionally, a set of context-aware access policies that govern user interactions over the shared content object is established. When a particular user requests an interaction over a shared content object, then interaction attributes associated with the request are gathered. The context-aware access policies are applied to the request by determining a set of extensible access permissions that are derived from the interaction attributes. The context-aware access policies are enforced by overriding the first set of resource access permissions with dynamically-determined access permissions. When a particular access request is denied, a response is generated in accordance with the set of extensible access permissions and the user is notified. In some cases, the access request is permitted, but only after the user provides a justification.

It may be desirable to identify the individuals as belonging to a particular group or having a particular status or position while maintaining the anonymity of the individuals within the particular group.

Abstract: A system performs digital notarization using a biometric identification service. A signature requesting service receives a request to validate a digital item with a signature for a person. The signature requesting service provides a payload that identifies the digital item and/or the person to an identity service. The identity service obtains one or more digital representations of biometrics for the person, determines an identity for the person, and returns a data structure including the payload and one or more identity attestations regarding the determined identity. The identity service encrypts at least a portion of the data structure using a private encryption key. A public encryption key for the identity service can then be used to decrypt the portion to verify that the data structure was generated by the identity service after determining the identity. In this way, validation can be verified to the full trust level of the identification service.
