New Encryption Tech

[Anchor Lead]

In a technological race against counterfeiters, Korean researchers have developed an encryption technology 100 times more sophisticated than the QR code. Let’s find out more.

Several hundred thousand counterfeit products are reported each year. Even the QR codes used as a counterfeit prevention measure are being forged, making it more difficult to distinguish between fakes and original goods. Korean researchers have developed an encryption technology which uses lasers to produce ultra-fine lines. The lines measure just 10 micrometers in width, a tenth of a human hair. The technology is 100 times more intricate than ordinary QR codes. Instead of directly applying lasers, the angle created when two laser beams intersect is adjusted to modify the arrangement and thickness of the lines.

The technology also utilizes holograms, whose patterns appear differently depending on the viewing angle. Researchers say they can embed the technology through inscription in unnoticeable areas such as the nib of a fountain pen or the edges of a ring, to prevent forgeries. The technology has been transferred to a small company which is set to commercialize it next year.

The Korea Institute of Machinery & Materials which completed domestic patent registration procedures has also applied for a patent in the United States.
