Abstract: Obtaining and/or validating user credentials at client devices is described. This disclosure describes methods of generating representations of credentials for groups of users or for individuals. Representations for these credentials can be managed by a server or collection of servers, and distributed to appropriate users' client devices. These representations can then be outputted for evaluation by a credential authority, who confirms that the credential possessed by a given user is valid. A credential authority may be a person and/or a device that validates a credential.

Abstract: This specification describes technologies relating to applying electronic signatures to content items. In general, one aspect of the subject matter described in this specification can be embodied in methods that include receiving a content item and receiving a request to electronically sign the content item by a user by associating the content item with a credential associated with the user, the request comprising data identifying the credential from among a set of credentials that are associated with the user. The method may further include generating a package comprising the content item and data for the identified credential.

Abstract: A method comprising: storing, at a server, an electronic resource that has been electronically signed by a user; associating the electronic resource with an identifier; receiving, at the server and from a client device, a request to identify the user who electronically signed the electronic resource, the request including a reference to the identifier; responsive to receiving the request to identify the user who electronically signed the electronic resource, identifying, based on the reference to the identifier, the electronic resource stored at the server; responsive to identifying the electronic resource stored at the server, identifying the user who electronically signed the identified electronic resource; and transmitting, from the server to the client device, an indication of an identity of the user who electronically signed the electronic resource.

Abstract: The disclosure of the present document can be embodied in a non-transitory computer-readable medium storing instructions that cause one or more processors to perform various operations, including, receiving, from a first client device associated with a user account of a first user, a request for sharing a document. The document is associated with a credential of the first user, and the credential is associated with the user account of the first user. The operations include transmitting, in response to the request, a code associated with the document, and receiving, from a second client device, a request to access the document. The request to access the document includes the code associated with the document. The operations include determining, based on the request to access the document, that the second client device is authorized to access the document, and communicating, to the second client device, a message including information about the document.

Abstract: In one implementation, a computer system maintains one or more permissions associated with a credential held by a first user, where at least one of the one or more of permissions is delegatable by the first user to one or more other users. The computer system receives an indication that the first user has chosen to delegate a particular permission from amongst the one or more permissions to a second user, wherein the particular permission is needed to perform a particular type of action. Based on the first user indicating a choice to delegate the particular permission to the second user, the computer system associates the delegation of the particular permission with the second user. Based on delegating the particular permission with the second user, the computer system enables the second user to perform the particular type of action.

Abstract: An application executed on a client device displays a user interface that receives input related to outputting credential information, wherein the application is configured to manage credentials that are associated with a validation system. The application receives, through the user interface, first user input to output a representation of a first credential in a manner that enables a credential authority to validate the representation. In response to receiving the first user input, the application identifies a location of the client device. The application determines whether the location of the client device is associated with a first region where the first credential is enabled for validation. In response to determining that the location of the client device is associated with the first region where the first credential is enabled for validation, the application displays, on the user interface, the representation of the first credential.

Abstract: Data associated with user identities within an electronic social networking platform is extracted from the electronic social networking platform. A request is received to filter the user identities based on a specified value for a characteristic. Based on data associated with the user identities that was extracted from the electronic social networking platform, a subset of the user identities is identified who have the specified value for the characteristic. An indication of content to be delivered to the identified subset of user identities is received. As a consequence, the content is delivered to at least some of the user identities within the identified subset of user identities.

Abstract: In one implementation, data associated with user identities within an electronic social networking platform is extracted from the electronic social networking platform. A subset of these user identities may have endorsed a particular entity within the electronic social networking platform, and a segment of user identities within this subset may be identified. Content then may be delivered to at least some of the user identities within the segment.

Abstract: In one implementation, a computer system receives a request from a first user to perform an operation related to a file stored by the computer system. The file is associated with a second user, and the second user has shared the file with the first user with one or more conditions on the usage of the file by the first user. Based on the first user requesting to perform the operation, the computer system evaluates whether the one or more conditions placed on the usage of the file by the first user allow the first user to perform the operation. Based on evaluation results, the computer system determines that the one or more conditions placed on the usage of the file by the first user allow the first user to perform the operation and authorizes performance of the operation.

Abstract: In one implementation, data associated with user identities is extracted from an electronic social networking platform. Based on the extracted data, at least some of the user identities are classified as fitting one or more of multiple different profiles. A first subset of user identities classified as fitting a first profile is identified. A second subset of user identities classified as fitting a second profile is identified. In addition, values for a particular characteristic associated with user identities identified as belonging to the first subset are identified, and values for the particular characteristic associated with user identities identified as belonging to the second subset are identified. A display then is caused that reflects the identified values for the particular characteristic associated with user identities identified as belonging to the first subset and the identified values for the particular characteristic associated with user identities identified as belonging to the second subset.

Abstract: In one implementation, data that reveals a user identity's engagement with an electronic social networking platform is extracted from the electronic social networking platform. A numeric measure of the user identity's engagement with the platform then is calculated based on the extracted data.

Abstract: A method, comprising: storing, at a server device, an electronic resource; receiving, at the server device and from a client device associated with a first user, a request on behalf of the first user to access the electronic resource; responsive to receiving the request on behalf of the first user to access the electronic resource, enabling the client device associated with the first user to access the electronic resource; while the client device associated with the first user is accessing the electronic resource, receiving, at the server device and from the client device associated with the first user, a request to validate a representation of a credential purported to represent another user received by the client device; validating the received representation of the credential as representing a second user; and responsive to validating the received representation of the credential, enabling the first user to electronically sign the electronic resource.

Abstract: Location information of a client device associated with a credential is determined to be tracked. The credential has been granted to a user of the client device by a credential granting authority to indicate a status of the user with the credential. Known location data that indicates known locations is maintained. The credential data is associated with each of the known locations, and geographic data for each of the known locations. A location of the client device associated with the credential and a particular time associated with the location is determined. A subset of the known location data that defines one or more locations that are known for the credential is accessed from the known location data. The location of the client device associated with the credential is compared with geographic data included in the accessed subset of the known location data.

Abstract: Obtaining and/or validating user credentials at client devices is described. A phrase may be generated based on one or more index values determined according to a function of time and a credential identifier identifying a user credential. The phrase may be output by the client device for validating the user credential.
