Information processing system and method, and information processing device and method

An information processing method for an information processing system that includes

• one or a plurality of center servers to each of which one or more zone servers are allocated,
• a plurality of zone servers each of which belongs to one or more of the center servers, one or more gate controllers different from each other being allocated to each of the zone servers, and
• a plurality of the gate controllers each of which belongs to the corresponding zone server, and communicates with a storage device, wherein
• each of the center servers manages user data that is data about a user on the basis of identification data,
• each of the zone servers acquires the user data corresponding to the identification data and supplied on the basis of prediction data corresponding to the identification data, acquires the identification data from the gate controller allocated to the corresponding zone server, and processes the acquired user data that corresponds to the acquired identification data, and
• each of the gate controllers acquires the identification data from the storage device that stores the identification data, and supplies the acquired identification data to the zone server to which the corresponding gate controller belongs.

An information processing device that belongs to one or more center servers, one or more gate controllers being allocated to the information processing device, the information processing device comprising:

• a user data acquisition unit that acquires user data that is data about a user corresponding to identification data, and is supplied on the basis of prediction data corresponding to the identification data;
• an identification data acquisition unit that acquires the identification data that is read from a storage device storing the identification data, and is supplied from the gate controller allocated to the information processing device;
• and
• a user data processing unit that processes the user data that corresponds to the identification data acquired by the identification data acquisition unit and is acquired by the user data acquisition unit.

An information processing method that belongs to one or more center servers, one or more gate controllers different from each other being allocated to the information processing method, the information processing method comprising:

• acquiring user data that relates to data about a user corresponding to identification data, and is supplied on the basis of prediction data corresponding to the identification data;
• acquiring the identification data that is read from a storage device storing the identification data, and is supplied from the gate controller allocated to the information processing method;
• and
• processing the acquired user data that corresponds to the acquired identification data.
