It appears that snoops may soon have access to a powerful tool that may likely be used to abuse privacy.

A team of researchers at The University of Texas at Austin’s Cockrell School of Engineering has built the first-ever circulator for sound. The team’s experiments successfully prove that the fundamental symmetry with which acoustic waves travel through air between two points in space (“if you can hear, you can also be heard”) can be broken by a compact and simple device.

“Using the proposed concept, we were able to create one-way communication for sound traveling through air,” said Andrea Alù, who led the project and is an associate professor and David & Doris Lybarger Endowed Faculty Fellow in the Cockrell School’s Department of Electrical and Computer Engineering. “Imagine being able to listen without having to worry about being heard in return.”

This successful experiment is described in “Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator,” which will be featured on the cover of Science in the Jan.

Dianne Feinstein: NSA Snooping Isn’t ‘Surveillance’

diane-feinstienHey, remember when you could tell the difference between Republicans and Democrats, or at least they cared enough to try to fool you into thinking there was a difference?*

No? Okay. Never mind. Business as usual as Dianne Feinstein (D-State of Hypocrisy) defends the NSA’s surveillance programs. Whenever I read this kind of thing I’m reminded of an abuse victim defending his or her abuser: “You don’t understand him like I do!”

Via Raw Story:

Dianne Feinstein, the chair of the US Senate committee charged with holding the intelligence establishment to account, declared on Monday that the National Security Agency’s mass collection of phone records is “not surveillance” and should be maintained as an essential tool to combat terrorism.

Feinstein made the case for retaining the program, which routinely collects and stores the phone records millions of Americans, in an op-ed for USA Today, in which she wrote that the NSA’s work had been “effective in helping to prevent terrorist plots against the US and our allies”.

ProPublica Reveals Depth of Government Snooping Powers

While much of the Petraeus story focuses on the government’s email snooping powers, non-profit news organization ProPublica reminds cellphone users that Big Brother has their numbers, too. So to speak:

“The guest lists from hotels, IP [computer] login records, as well as the creative request to email providers for ‘information about other accounts that have logged in from this IP address’ are all forms of data that the government can obtain with a subpoena. There is no independent review, no check against abuse, and further, the target of the subpoena will often never learn that the government obtained data.”

It’s not just email. In July, Rep. Edward Markey, a Democrat from Massachusetts, cajoled major cellphone carriers into disclosing the number of requests for data that they receive from federal, state, and local law enforcement agencies: In 2011, there were more than 1.3 million requests. As ProPublica reported at the time, “Police obtain court orders for basic subscriber information so frequently that some mobile phone companies have established websites — here’s one — with forms that police can fill out in minutes.
