US Patent 11695555 Federated key management

A system uses information submitted in connection with a request to determine if and how to process the request. The information may be electronically signed by a requestor using a key such that the system processing the request can verify that the requestor has the key and that the information is authentic. The information may include information that identifies a holder of a key needed for processing the request, where the holder of the key can be the system or another, possibly third party, system.
