Abstract
Described embodiments generally relate to methods of encoding data on a data storage medium and methods of decoding and reading such encoded data. Other aspects relate to systems or apparatus for performing these methods. Still other aspects relate to systems and methods for monitoring use of data recorded on data storage media. These aspects are particularly suited to protecting proprietary data against unauthorized or excessive copying, where the proprietary data is embodied on a data storage medium that is publicly available for rent or sale.
