1. A method of managing user identity authentication data, comprising:
authenticating, at a management device, a query request from a query requester for original identity data of a user to be queried, the query request including at least a key for encrypting the original identity data to be queried;
in response to the query request being successfully authenticated, sending authorization information for the query request to the query requester;
determining, based on mapping information associated with the original identity data stored by one or more of a plurality of authentication devices, at least one of the plurality of authentication devices to query for the original identity data; and
in response to receiving signature information corresponding to the query request from the user to be queried, transmitting the signature information and a key to the at least one authentication device, wherein the signature information indicates the user to be queried approves the request and was generated by a terminal device of the user to be queried based on the authorization information, the authorization information having been received at the terminal device of the user to be queried from the query requester.
