  • Patent number: 11444935
    Abstract: A method and system provide the ability to authenticate client services. A private key and a client certificate are created and delivered to a client. Based on the private key and the certificate, a client account is created for the client on a server. One or more signing or feature licensing configurations are created and authorized on the server for the client account. The client certificate and a request to perform a requested client service are received on the server from a client. The request includes configuration information for the requested client service. The server verifies the client certificate and determines whether the client is authorized to perform the requested client service. The determination is based on the configuration information and the one or more authorized client operations. Upon determining that the client is authorized to perform the requested client service, the request is processed the authorization is sent to the client.
