ABSTRACT:
An information processing apparatus including a recording medium setting part in which a recording medium is set is provided. The information processing apparatus includes a validity determination part for determining validity of a program by determining validity of validity determination data, wherein the program and the validity determination data are stored in the recording medium, wherein the validity determination part determines the validity of the validity determination data on the basis of a first comparison between a hash code generated from the program and a hash code obtained by decoding the validity determination data and a second comparison between machine specific data that is specific to the information processing apparatus and machine specific data obtained by decoding the validity determination data.
