My patent, US 10,176,661 B2 brings together the technology of fluorescent material doped onto nanoparticles with the technology of Digital Signal Processing (DSP).

The outcome of this union is snippets, or passbands, which are little pieces of the full-wide peaks profile produced by a given array of rare earth materials imprinted onto a value document, or value item.

My system uses a Finite Impulse Response filter, which is a programmable Fast Fourier transform algorithm to squint at the full-wide peaks profile in millions of distinctly different ways, so each value document or value item can have its own authenticating key. These keys are stored in a database and can be looked up according to their file numbers. The key and the value document are then compared. If the “fit” is good enough, then the document, or item, is rated “authentic”, and if not, then not.

Fluorescent materials have been used on currency before. DSP has been around for a long time, mostly in relation to digital recordings of music, where brick wall filters can be used to improve fidelity, or tune a radio for example.

DSP can also be used in conjunction with a Digital Optical Spectrum Analyzer, and that how snippets can be made (tightly defined passbands) from a full wide optical peaks profile.

The passband filter that makes these snippets can make several of them at one time, and can be programmable, if its fed by variables that tell it exactly where to make the snippets on a full-wide peaks profile of fluorescent photons being “seen” by a sensor, and converted by a transducer.

Thus is born the programmable multiple bandpass filter which is the working unit that makes snippets inside the total authentication apparatus.

The strongest features of my invention include: 1 the fact that a single set of fluorescent materials can be used for millions of authenticatable documents (or items), and 2 the fact that is a breach of security somehow occurs in my system, I can change the snippets that will be used to authenticate my documents (or items) going forward. My system is operationally robust — it can take a lick’in, but keep on tick’in.

This is a meaningful improvement over all that has gone before, and as security systems are collapsed, hacked, compromised, or breached every year on larger and larger scales, now running into billions of accounts, companies will turn to authentication methods that are resilient, responsive, robust, and re-programmable.

My patent is the only such invention in the field of Photon/DSP. It is better than all the prior patents. It is new and useful, which is the standard for a patent to issue.

My patent was issued on 8 January 2019, and it has a 20 year life, so there’s plenty of time for some corporation to come to the view that my invention would be highly useful to them, and make big profits for them. A big bank, for example, could use my method to issue Paper Bullion Bank Bills, and thus vastly increase its wealth management activity, and its international trade activity. There would be numerous follow-on patents that the bank could file as it rolls out the various applications, which will include tags for value items, DNA tags, custody account personalty tags, auction tags, ID cards, and signalling systems.

The bank could sell off all the applications it does not need, and keep the applications that give it a major competitive advantage in the banking space, like money orders, and letters of credit, and gem tags.

My work is mostly in particle physics and photonics, not in having a lot of business contacts, or a big rolodex. So the partnership between me, the inventor, and a big global bank, the exploiter, is natural and benefits both of us. The bank does not know photons like I know photons. I don’t know who to call, like the bank knows who to call.

A major global bank could make $20 Billion worth of new business for itself over the life of my patent, not counting the revenues from the natural roll-out follow-on patents, which it would develop and own as first mover in new markets. It could get back what it pays me with a few phonecalls in a week or two.

The current price of my patent is $8 million (enough for a small apartment in Paris). After 1 April, 2019, the price will go up to at least $16 million (enough for a pretty large apartment in Paris). Good inventors who get strong patents on fundamental core technology breakthroughs should have a few golden years at the close of their days, so what I’m asking is just what is right.
