Abstract:
1. A process management apparatus comprising: a data transmission/reception unit configured to execute data transmission/reception to and from an information recording medium including a data storing unit configured to store identification data of an object to be managed; a process data holding unit configured to hold process data representing a process; and a process pass certificate data generation unit configured to generate process pass certificate data representing the passage through a process from said process data representing said process; wherein said data transmission/reception unit is configured to execute data transmission/ reception of said identification data, said process data and said process pass certificate data to and from said information recording medium, wherein the process pass certificate data is generated in accordance with both the identification data and the process data with performing calculations based on either one of a hash function or an encryption key; wherein the process pass certificate data is stored in the data storing unit of the information recording medium; wherein the data transmission/reception unit is arranged to receive both the identification data and the process pass certificate data having been stored in the data storing unit provided within the information recording medium; wherein the process pass certificate generation unit is arranged to generate the process pass certificate data by using a hash function, in accordance with the identification data, the process data, and the process pass certificate data; and wherein the data transmission/reception unit is further arranged to cause the information recording medium to store, in the data storing unit, both the process data and the process pass certificate data.
