<p>When data is determined not to be correct, a part of the data is used again. Data (105) is input to an input unit (101) and processed data (107) is generated in a processing unit (102). According to generation of the processed data (107), an authentication data generation unit (103) generates authentication data (108) for authentication of the processed data and outputs in an output unit (104) data to be authenticated (106) in which the processed data (107) is correlated with the authentication data (108). By including data (105) input to the processed data (107), even if the processed data (107) cannot be authenticated, processing can be performed by using the data (105) if authentication of the data (105) can be guaranteed. Moreover, flexible processing can be specified by including in the processed data, state return information required for processing when the authentication cannot be obtained.</p> |
