PROBLEM TO BE SOLVED: To realize efficient data processing by effectively utilizing each data processor and to detect the alteration of data on a network. SOLUTION: A device type DT indicating the type of a data processor 1 and a device identifier ID which identifies each device are assigned to each data processor 1. Each data processor 1 which fractionizes a series of data processing, forms a frame by adding processing sequence information containing a plurality of individual. corresponding processing information to data to be processed at every fractionized processing, and sends the frame. The individual processing information contains a sequence number indicating the processing order, a processing command designating an instruction code to be executed, device identifying information designating a data processor to be used for processing, and the sequence number contained in the individual processing information to be processed next and each data processor 1 performs a series of data processing by sending the frame toward the next after performing data processing. |
