1. An authenticating system for determining the authenticity of an object having a secure glyph thereon comprising:
a) a secure glyph for determining authenticity comprising:
i) an intellectual property protected feature; and
ii) a machine readable feature having a covert and/or overt portion;
wherein said intellectual property protected feature is recognized either alone as a machine readable feature, or recognized in combination with at least a portion being a machine readable feature, by an authenticating apparatus to determine authenticity;
wherein the machine readable feature of the secure glyph further comprises at least 3 degrees of rotational symmetry;
wherein the secure glyph comprises at least a first taggant material and a second taggant material each comprising a characteristic excitation pattern and emission spectrum, and wherein the characteristic emission spectrum of the first taggant material is used to excite the characteristic emission spectrum of the second taggant material in a cascade of excitation patterns and emission spectra;
b) an object having the secure glyph applied;
c) a database having stored data related to signal response properties for said secure glyph;
d) an authentication reader having:
i) a signal generating source for generating a signal response from said secure glyph;
ii) a signal response detector for detecting said signal response, and
iii) a signal processing unit (SPU) for analyzing the detected signal response and comparing said signal response detected with data stored in said database and authenticating said object to a user based on a result obtained by said authentication reader from the comparison between the signal response detected and the data in the database and the results of a naked-eye visualization of the glyph,
wherein the reader further comprises an output device connected to the signal processing unit, configured for outputting the result of the authentication to a user, and allowing or disallowing an object to be used based upon such results.
