An identification information apparatus detects first and second boundary position information representing boundary positions on a high-order bit side and a low-order bit side of codes formed of components, extracts a colluder group matching with a set of the first and second boundary position information among colluder groups including combinations of an arbitrary number of identification information which is not more than a predetermined maximum number, and detects identification information which is common to a plurality of the colluder groups. |
