Electrical fluctuations as a watermark for audio and video recordings

Audio recordings usually include a low-level background noise caused by electrical equipment. The hum contains small frequency fluctuations which are propagated consistently over entire power grids. By storing the pattern of grid-wide fluctuations in a database forensics experts are able to use the hum as a watermark. This can determine when the recording was made, where it was made and whether it was recorded in a single edit. [more inside]

Mat Honan of Wired has a covetableTwitter username (@mat). Recently hackers tore his digital world apart in an attempt to commandeer it. Now he reflects: The age of the password has come to an end; we just haven’t realized it yet. And no one has figured out what will take its place. What we can say for sure is this: Access to our data can no longer hinge on secrets—a string of characters, 10 strings of characters, the answers to 50 questions—that only we’re supposed to know. The Internet doesn’t do secrets. Everyone is a few clicks away from knowing everything.
