Unlocking Huge Storage Potential with Everyday Plastic Through Cutting-Edge 3D-Printed Holography - Storing Keys and Addresses Efficiently

There is no shortage of ways to store and encode data in the ever-evolving field ofdata storage — adding to that list on March 6th, researchers published a paper titled “Encoding terahertz holographic bits with a computer-generated 3D-printed phase plate “ for open access on_Nature.com’s Scientific Reports_ . This story reached us through aPhys.org writeup .

Based on the abstract in the original report, a 2D 576-bit data code can be produced using a diffractive phase-plate element. The data actually encoded in the testing was a 256-bit private Bitcoin wallet key with redundancy, so it’s a little unclear whether 256-bit is the real upper-limit or a user could use all 576 bits without redundancy. In any case, that’s not a lot of storage— but for the right pieces of digitized information, it may be all you need.

The process works by using a combination of the right FOSS (Free and Open Source Software) on Github (namelylibdmtx andpylibdmtx ) and thebest 3D printers , one can map and then print holographic data to a regular piece of plastic. In order for the data to be read once mapped to this piece of plastic, the usage of a terahertz wave is required— which is likely the most expensive part of the process.

So if this implementation of HDS (holographic data storage) still involves the use of expensive equipment, what’s so impressive? Well, typically, even the simple creation of functioning holographic storage is an incredibly expensive process that requires high-end laser-etching. Following this, the basic storage medium can be created by just about anybody with access to the original paper, Github, a 3D printer, and the computing knowledge to make it all work.

One of the researchers who worked on the piece, Evan Constable of the Institute of Solid State Physics at TU Wien, said “In this way, you can securely store a value of tens of thousands of Euros in an object that only costs a few cents.” While there is obviously a greater barrier of entry to even having equipment capable of reading this form of storage, fabrication through 3D printing is about as cheap as storage is ever going to get.

Of course, this tech isn’t going to be taking the place of the latest and greatest cutting-edge NVMeSSDs , or anything like that. But it doesn’t have to. Being able to store cryptographic keys on a cheap piece of 3D manufactured plastic sounds like something out of science fiction or some pseudoscientific spy thriller— but now, it’s becoming a reality.
