PURPOSE:To obtain an information processing system with fast response and high reliability by checking an identification name of reception data of two reception systems to detect data mission of a reference system thereby adopting data of a spare system. CONSTITUTION:One data RD1 and other data RD2 subjected to duplication are received respectively by a reference system reception section 11 and a spare system reception section 21, stored respectively in files 12, 23 at the reception of data of each unit and copied to files 22, 13. Then a file record number and a data identification name of the stored data are given to data analysis processing sections 14, 24 successively, both the processing sections read the data from the files to attain analysis processing. The processing section 24 checks the presencef of the storage of the data identification name by a processing request register 26, and when it is stored, the identification name is deleted, and when not stored, the identification name is requested for deletion and the result is stored in the register 25. If missing of data takes place in the reference system side 10, the identification name left in the register 26 is detected by a reception section 21 and the record number of the files 23, 13 is transmitted to the processing sections 14, 24, where it is processed.
