Appeal No. 2004-0227
Application 09/140,151
THE INVENTION
The appellants claim a system and a method for providing a
substrate with security information. Claim 11, directed toward
the system, is illustrative:
11. A system for providing a substrate with a security
identification comprising:
a security signature comprised of a random distribution of
dielectric components affixed with said substrate, said
dielectric components having a dielectric constant sufficiently
larger than that of said substrate as to exhibit molecular level
electric dipole moments, that cause a detectable modification of
an external electric field passing through said substrate in
accordance with said distribution; and
a security signature detector configured to couple an
electric field with said substrate, and being operative to
measure a modification of said electric field by said random
distribution of dielectric components, and to store information
representative of said modification.
