I do this with rare earth elements called Lanthanides, that give off fluorescent photons when they are struck by primary photons.

To make my Lanthanides ink, I use a dozen elements, and a dozen nanoparticles as holders or substrates for the +3 or +2 ions of the Lanthanide element.

Because of the mix of Lanthanides (taggants) and the specific nanoparticles they are affixed to, one ink mixture will return a very specific peaks profile, which is the intensity of the fluorescent photons at wavelengths 200nm to 1500nm.

A Peaks Profile looks just like a profile of mountain peaks, in the Rockies, or the Alps. It goes up and down across the spectral range, from the very hard UV (at 200 nm) to the very soft infrared at 1500 nm, and of course the visible range of light is also included (about 550 nm to about 750 nm). So different peaks at different colors across the frequency domain. Maybe this color is high intensity fluorescent return and that color has no fluorescent return, or very little, like a tiny mountain in an alpine chain.

I don’t want to mix a different batch of expensive ink for each item to be authenticated. So what I do, is break the peaks profile into snippets. This can be done three ways —- the total number if snippets, the width of each of the snippets, and the placement of each snippet along the peaks profile (Nature chooses that, not me — well, I choose the ions, so a little bit me).

I use Finite Impulse Transform and Finite Impulse Response circuits to make the snippets with programmable brick wall filters. It’s just like tuning on a radio that has digital (or synthetic) tuning. You punch in 88.1 fm and the radio goes straight to 88.1 fm by using brick wall filters to block out all frequencies below 88.1 and all frequencies above 88.1 — that’s why they are called brick wall filters.

Light and radio waves are exactly the same thing — electromagnetic waves. So fluorescent photons are just like radio waves. So my authentication machine can look just at a very tightly defined set of snippets among all the fluorescent photons that come back from the taggants zone.

US 10,176,661 B2 was granted on 8 January 2019, and I was not able to file it internationally, so many companies in many places have copied my inventive departure and filed patents to get the rights in their respective countries. Globally, my patent was the first, and it is, the bedrock patent, of all Photon-DSP technology.

So far, with tens of trillions of dollars sitting on the sidelines in cash, no venture capital person or firm has made an offer for my patent which is priced to move at $2 million.

One of the things you can make with it is ID cards.

Another is Paper Bullion Bank Bills.

Another is secure packages to contain rare metals.

A global bank could easily make $20 Billion in new business on my patent by the time it expires in 2039, (on 8 January of that year).

If they buy the patent from me, intervivos, they get pure fee simple absolute, and own the whole thing, and all the applications.

I’m 74. If they wait till I die, nobody gets the patent. You can only patent a new invention. On 8 January 2019 Photon-DSP was new. It will never be new again.

You can own the rest of my term on that patent by buying it from me inter vivos. So you have it free and clear till 2039. By that time you will have first mover advantage and nobody will catch up with you as a force in the market. You will file follow-on patents, like Elon Musk did for his Tesla engine. Those follow-on patents keep you ahead of any possible competitors. So your moat can last more than 20 years.

$2 million is what they spend on a garden party in the Hamptons, or Martha’s Vineyard. So there are people who could afford to buy my patent. A big bank would be an easy winner with my technology. A state that wants reliable ID cards might be another easy winner. Maybe TX, FL, NH, SD. A lawfirm that wants to mark evidence, like DNA, so it can be positively authenticated in Court, or the US Post Office that makes money orders that are counterfeited every year (about $2 Billion worth). They could pay me $2 million, and save $2 billion in one year.

If a venture capital firm reads my patent, sees its value, and wants to buy it as a flip, I’m OK with that. I think they could turn it over for a good profit in about a week. I do physics, math, chemistry, what do I know about wealthy people? No contacts with the “in crowd” (the ones who are not deplorables or breakfast tacos, like me).

I will help the buyer to properly apply my technology so it is extremely profitable. Raytheon, IBM, or Lockheed-Martin would be the ideal corporate buyer. Chase, UBS, or CITI would be the ideal bank buyer. TX, NH, or FL would be the ideal state buyer (to make ID cards).
