Abstract: This application provides a data storage method which is applied to a data storage device and includes: acquiring a first user identification and first user data of a first user; determining, from at least two preset distributed hosts in different areas, a first identification distributed host corresponding to the first user identification and a first data distributed host corresponding to the first user data; sending the first user identification to the first identification distributed host, so that the first identification distributed host stores the first user identification, and generates and stores a first identity identification corresponding to the first user identification; receiving the first identity identification; and sending the first identity identification and the first user data to the first data distributed host, so that the first data distributed host stores them in an associated manner.

Abstract: A transaction data processing method includes: determining one or more transaction key values and one or more transaction feature values of a to-be-processed transaction according to transaction information of the to-be-processed transaction; determining a rule union corresponding to the to-be-processed transaction according to the one or more transaction key values, the rule union including a plurality of to-be-matched rules; matching the one or more transaction feature values of the to-be-processed transaction sequentially with the plurality of to-be-matched rules in the rule union to obtain a rule matching result of the to-be-processed transaction; and performing a billing process of the to-be-processed transaction according to the rule matching result.

Abstract: A method for sample alignment is applied to a first participant system, where a first trusted execution environment is deployed at the first participant system. The method includes, in the first trusted execution environment, obtaining at least one first sample identifier of the first participant system; through the first trusted execution environment, obtaining at least one second sample identifier of the second participant system from the second trusted execution environment, where the second trusted execution environment is deployed at the second participant system; in the first trusted execution environment, determining the first initial intersection of the at least one first sample identifier and the at least one second sample identifier and performing the shuffle processing on all first target sample identifiers in the first initial intersection to obtain the first target intersection; and based on the first target intersection, determining the first sample alignment result.
