ABSTRACT:
A method for reproducing a recording medium comprising reading out identification data from a recording medium having recorded thereon data and the identification data, which identification data includes entity identification data and detection data. The detection data is generated using at least the entity identification data and indicates whether or not the entity identification data at least is authentic data. The identification recorded on the recording medium is read out, detection data is generated based on the entity identification data of the identification data as read out and the detection data extracted from the read-out identification data is compared to the generated detection data. When, as a result of comparison, the detection data extracted from the read-out identification data is coincident with the generated detection data, the outputting of the data read out from the recording medium is permitted.
