In some implementations, after one or more users have each been granted a respective access token allowing access to a resource device, revocation data is received by the resource device. The revocation data indicates that the previously granted access to the resource device should be revoked. For example, the revocation data may indicate (i) a user, role, or permission level for which access is revoked and (ii) a duration that access to the resource device was allowed. After receiving the revocation data, the resource device receives token data derived from an access token that allows access to the resource device. The resource device determines that the access token relies on authorization of the user, role, or permission level indicated by the revocation data, and in response, the resource device denies access.

Device access revocation

A method of controlling the sharing of data between entities that are in electronic communication with each other may include generating an authentication credential comprising an identifier for the target service and a unique signature, attenuating the authentication credential, and determining whether a client device is authorized to access the target service, and, only if so, providing the authentication credential to the client device. In an embodiment, the method may include receiving an access request from the client device, identifying that the authentication credential includes the unique signature and a third party caveat that is associated with a third party authentication service, in response to the identifying, determining whether the request also comprises a discharge credential for the third party caveat, and if the request includes the discharge credential, providing the client device with the requested service, otherwise denying the request.
