  • Securely updating information identifying services accessible via keys
    Patent number: 9438598
    Abstract: A first device may receive a service authorization instruction from a second device. The service authorization instruction may include one or more authorization parameters and an instruction to associate or disassociate a key, with a service, to permit or prevent the service to be accessed using the key. The key may be embedded in an application used to provide an application instruction corresponding to a request for the service. The first device may validate the service authorization instruction based on the one or more authorization parameters; and update, based on validating the service authorization instruction, information identifying services that are accessible using the key to permit or prevent the service to be accessed using the key without modifying the key embedded in the application.
