摘要：An information processing system includes a medium storing contents forreproduction, and a reproducing device to reproduce the contents. The reproducingdevice obtains a device certificate and transmits the device certificate to the medium. Thedevice certificate includes the reproducing device's type information, and the mediumencodes a media ID for identifying the medium according to an encoding algorithmselected according to the reproducing device's type information. The encoded media IDis transmitted to the reproducing device, which decodes the encoded media ID accordingto a decoding algorithm corresponding to the device type of the reproducing device, anddecrypts and reproduces data to which the obtained media ID is applied.
