Abstract: In an information providing apparatus, a rule storage unit stores a processing rule including, as a permitted processing method, a processing method permitted for equipment information transmitted from equipment. Further, a data provision unit acquires a provision request including a processing method of the equipment information as a requested processing method. When the requested processing method matches the permitted processing method included in the processing rule, a data processing unit processes the equipment information by the requested processing method. Further, the data provision unit transmits, as processed information, the processed equipment information to a request source of the provision request.
