An invention is an Idea, not a thing, or embodiment of the idea.

My invention is to edit the totality of fluorescent returns from a set on Ln+3 ions on nanoparticles, by dividing the spectral range from 300 nm to 1500 nm into “snippets” or segments of said spectral range. For example some snippets might be 382 nm to 406 nm AND 529 nm to 532 nm AND 592 nm to 638 nm AND 797 nm to 1285 nm AND 1372 nm to 1486 nm.

Some “snippets” are narrow, some are wide. Some are here some are there. There could be very few of them or there could be many, and all the variants between few and many.

The snippets are made by a variables set that runs through a chip that makes brick wall filters. So, for example, the snippet 382 nm to 406 nm is created by a brick wall filter that blocks all wavelengths shorter than 382 nm and all wavelengths longer than 406 nm. This passband filter only lets through wavelengths between 382 nm and 406 nm (inclusive). It’s a bandpass filter that lets a snippet of the total frequencies detected by the CCD sensors through. That band of frequencies passes through and all the rest are blocked. The bandpass filter is electronically created by part of the variables set that sets up all the brick wall filters for that edited version of the whole spectrum of fluorescent light coming off a specific particular seal that is identified by a file number.

So I mix digital signal processing with fluorescent light (photons) and the idea that is my invention is called Photon-DSP.

From one seal, or one formula for fluorescent ink (like in a Bank Bill) I can make millions of authentication Photon-DSP signals. Each signal is totally unique. And they vary quite a lot (number of snippets, width of the various snippets, location on the spectral range of each snippet).

My seals or inks are tested by me in the lab. I use one particular variables set to make snippets for that seal. Then I store the snippets in a numbered file on a library chip in my authentication machine.

If that same seal ever comes back around, and produces fluorescent light, my charge coupled detectors will pick up the incoming wavelengths, array them, and compare that array to the numbered file on the library chip, Not to ALL the files on the library chip, JUST to that numbered file. The goodness of fit must be 95% or greater. Which is good enough. I could make it 99% but the machine would operate more slowly using thinner delta-x slices (and more of them).

Getting a 95% fit would mean the Ln+3 ions are right, the molar concentrations of them are right, the crystal lattice holding them is right, the seating of the Ln+3 ions in the substrate (lattice) is right (scintering, annealing, electro-deposition, microwave baking, physical pressure, etc).

So it takes a lot to get 95% right. Most attempts to fake one of my seals, or inks, will fail utterly and never had much of a chance. The gain from a forgery that passes the test is very small. The cost of making said forgery is very large. Crimes like that are just not done.

My inventive departure from all prior art is very great. My inventive idea is nothing like what was in the prior art. My invention is a totally new technology call Photon-DSP.

My patent is for sale and can be assigned by me in fee simple absolute — contact robert.gary@gmail.com. My price on 21 September 2025 is $260,000.00 two hundred and sixty thousand dollars.

If buyer appears and my patent is assigned to that buyer, I will remain in USA for about a week. After that i will be in Lausanne Switzerland, where know a lot of people all the languages and many of the local towns in the Canton of Vaud (like Rolle, and Gstaad).
