Encrypt Information In Images Without Distortion

Nomikos writes "C|Net reports: Researchers have created a new way to encrypt information in a digital image and extract it later without any distortion or loss of information. A team of scientists from Xerox and the University of Rochester said that the technique, called reversible data hiding, could be used in situations that require proof that an image has not been altered."

    When, oh when, will Slashdot dump myaql for a higher quality replacement?

    With a recent NY Times article saying that OSDN is (barely) profitable, isn't it nearly time to reinvest some of those gains in self-improvement?

    Isn't it time to abandon the low-quality opensource mysql, and replace it with a commercial solution? Failing that, how about postgresql?

      OSDN will be gone in less than 2 years.

      I'll laugh when it happens.

      Slashdot has degraded into microsoft bashing, while hosting microsoft ads. I'm nearly certain a majority of slashdot readers USE microsoft, but the posting tools insist on bashing because the editing tools post pathetic anti-MS stories.

      good riddance, OSDN.

      I say that mysql sucks, and that Slashdot is only hurting itself by continuing to use it, what with the daily (or more frequent) database server failures.

    I've had that technique for years. It's called a checksum.

    It isn't meant to prove anything. I actually LIKE microsoft, I just find it funny that the mass of readership here pretends to hate them for some undefined reason, as do the editors, yet the editors still run their ads in prominent locations.

    If the editors/owners of this site had any moral fiber, they'd stand by their comments and not run Microsoft ads at all. It'd be a completely stupid business decision, but that would be the way true "Open source advocates" would handle the situation.

      Same thing happened to me (in 1.1). the image was coming from adlog.com.com -- I blocked, refreshed and another ad took its place from adlog.com.com.. Block, refresh, and this time no ads.
