HexaLock announced today that HexaLock's 4th generation, Virtual Digital Hologram (VDH) copy protection technology is now available, worldwide. VDH technology has been in use for the last year exclusively within the military and government sectors. To date, media containing VDH technology has proven to be 100% resistant to all copying methods known to HexaLock and its customers.

"The VDH security element is a digital hologram, formed by special bit patterns that provide a Hologram effect to the CD/DVD reading device, said Mr. Eyal Cohen, HexaLock CTO. "The VDH effect is not an optical hologram, however, this is a good model to help explain the way VDH works. By looking on an optical hologram from different angles, the human eye can see different views. If you take a picture of an optical hologram, the 3rd dimension disappears. The result is a 2D picture that represents the view from a specific angle. HexaLock VDH technology is very similar. When making a copy of an original protected disc the VDH pattern will disappear. Instead, a static bit pattern will appear. The HexaLock software will detect absence the VDH pattern and act accordingly."
