Feasibility of edge delay symbols for copy protection in optical disks

The basic idea of edge delay symbols for copy protection in optical discs and its feasibility test were performed in this work. The presented study showed possibility of edge-delayed symbols as one of promising methods for copy protection of digital contents. Edge-delayed symbols called fingerprint which are uncopyable symbols cannot be recorded by conventional CD-recorders and even by mastering equipment which do not have the ability of edge delay.
