While the courts decide the legality of posting code that subverts DVD encryption, a Rhode Island company is on a mission to develop a new security method that will make discs self-destruct after a specified amount of time.
Less than a year after Circuit City put an end to its ill-fated Divx format, the proprietary pay-per-view DVD player, SpectraDisc is working on a self-destructing DVD technology that works with existing DVD players.
SpectraDisc, a spin-off from Spectra Science, a Providence, Rhode Island developer of laser technologies, is working on a special material to coat DVD discs, which start to self-destruct from the first moment of play. The coating is only around half a micron thick, around 1/200th of the thickness of a human hair. The thickness of the coating determines how long the disc lasts. The time limit can range from minutes to three days.
