A data processing device includes an image capturing unit for capturing an image so as to generate digital data, a time certification request unit for requesting time certification of the digital data in order to acquire time information regarding when time certification was performed, and a storage control unit for controlling the digital data associated with the time information to be stored in a storage destination. Thus, time certification of an image can be easily performed, and confirmation thereof can also be readily performed.
