In a new approach to security that unites technology and art, EPFL researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to ...

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate. As the demand for digital security grows ...

Encryption is a term that many of us have come across, but what does it mean? To put it simply, encryption is the encoding of information. Various online services use it to keep your data private and ...

MicroAlgo Inc. (the "Company" or "MicroAlgo", NASDAQ: MLGO) has developed a quantum image XOR encryption algorithm built on quantum mechanical principles to deliver reliable protection solutions for ...

In a world first, researchers from the University of Ottawa in collaboration with Israeli scientists have been able to create optical framed knots in the laboratory that could potentially be applied ...

Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL’s School of ...

Ink containing polymers that can store data has been used to write a letter containing a hidden message – the encryption key to unlock a text file of L. Frank Baum’s The Wonderful Wizard of Oz. Eric ...

If you have young kids, you'll relate to the value of being able to speak in code. For a few years, I was able to use Pig Latin to speak covertly around my kids. It was handy, and surprisingly ...
