Photon-DSP Technology can use Natural Fluorescence AND LED based light to create an Authentication Peaks Profile.

The benefit of adding in some LED light as supplement to a Ln+3 based peaks profile is that I can use wavelengths that are not found in any Ln+3 based fluorescence.

Also I can use intensity levels not attained by any Ln+3 fluorescent ions. I can turn up the LED to amplitudes never reached by natural fluorescence.

This means a lot more variation in the authentication peaks profiles, and far more certainty that a peaks profile has not been reverse engineered by replication of a mix of Ln+3 ions.

The snippets are another security measure. The full peaks profile is NOT what is used to verify an authentication. It’s an edited down version based on snippets that IS used.

The LED based (vs natural Ln +3 based) photons in the snippets will stand out very distinctly, particularly because their amplitude can be so much greater than natural fluorescence ever attains.

So adding in some LED based light is a good idea, and was NOT described in the granted patent US 10,176,661 B2 and may be the content of one of my follow-on patents, or your patent that cites my granted patent as “Prior Art”.

I want a big company like GE, IBM, Raytheon, or Google to use my technology, and get Photon-DSP seals into regular use in the market. They can be used on ingots, bars, coins, pills, ID cards, fashion items, rare metals, and critical parts (turbine blades, hip joints).
