摘要：The present invention relies on one or more intrinsic physical or chemical
characteristics of the substrate materials to distinguish unauthorized duplications of
information-carrying substrates. In one aspect of the present invention, a method is
disclosed for preventing unauthorized duplication of information to be distributed on
information-carrying substrates, by requiring such distribution to be through a substrate
of a type selected from a designated class of substrates. Unauthorized duplication can
be identified by relying on at least one designated intrinsic physical or chemical
characteristic that distinctively represents the type of substrate. The designated intrinsic
characteristic is detected by an information processing device that is configured to
operate to access the information authorized to be distributed using the type of
substrate when the designated characteristic has been detected. Accordingly, any
duplication of the information on other types of substrates outside said class of
substrates would be recognized as not being an authorized duplication by said
information processing device. By controlling the availability of the information-carrying
substrate material to only authorized information-carrying substrate producers for
production of the information-carrying substrate, unauthorized duplication of
information-carrying substrates by unauthorized production entities can be prevented. In
a further aspect of the present invention, a process is disclosed for the prevention of
unauthorized duplication of information-carrying substrates. The process comprises
monitoring the 'order to delivery' process such that information-carrying substrates are
produced without allowing substrate material and/or substrates to be obtained by an
unauthorized party.
