The invention relates to a method for generating an identification data block (ID) for a data carrier (41), which data carrier (41) has a multiplicity of logical data blocks (300) continuously numbered with respective block numbers in a data block size, a reading of the data of the logical data blocks is carried out and the generating of the identification data block (ID) is carried out by means of a combining function from read first data of a logical first data block (301) defined by a first block number and from read second data of a logical second data block (302) defined by a second block number, wherein the logical second data block defined by the second block number is determined in dependence on the read third data of a logical third data block (303) defined by a third block number.
A method for generating an identification data block (ID) for a data carrier (41), which data carrier (41) has a multiplicity of logical data blocks (300) continuously numbered with respective block numbers in a data block size, in which method a reading of the data of the logical data blocks (300) is carried out and the generating of the identification data block (ID) is carried out by means of a logic operation from first data read of a logical first data block (301) defined by a first block number and from read second data of a logical second data block (302) defined by a second block number, wherein the logical second data block defined by the second block number is determined in dependence on a read third data of a logical third data block (303) defined by a third block number.
A device (10) for generating an identification data block (ID) for a data carrier, which data carrier has a multiplicity of logical data blocks (300) continuously numbered with respective block numbers in a data block size, which device comprises:
