ABSTRACT:
An information reproducing apparatus of the present invention includes a secure module and a main memory. The information in the secure module can not be accessed from outside. The secure module reads, using a direct access method, information relating to software stored in the main memory. The secure module checks a falsification of the software by comparing the information read with the information stored in advance in the secure module.
