School District Halts Webcam Surveillance

Tuesday, March 9th, 2010

A suburban Philadelphia school district is deactivating a webcam, theft-tracking program secretly lodged on 2,300 student laptops following allegations the device was used by administrators to spy on a boy at home.

“I think given the concerns of parents and community members, I think we have a responsibility to at least take a pause and review the policy,” Lower Merion School District spokesman Doug Young said in a telephone interview Thursday evening.

The move came a day after the 6,900-pupil district, which provides students from its two high schools free Macbooks, was sued in federal court on allegations it was undertaking a dragnet surveillance program targeting its students — an allegation the district denied. Young said the computer-tracking program was activated a “handful” of times solely to track a missing laptop.

The suit was based on a student’s claim, acknowledged by the district, that the webcam was used by school officials to chronicle “improper behavior” based on a photo the computer secretly took of the boy at home. (.pdf) in November.

The assistant principal at Harriton High informed the student “that the school district was of the belief that minor plaintiff was engaged in improper behavior in his home, and cited as evidence a photograph from the webcam embedded in minor plaintiff’s personal laptop issued by the school district,” according to the lawsuit.

Young declined to directly say whether the program was activated in this instance to locate a missing laptop. He said the district only activates it when there is a reported missing laptop, and urged Threat Level to draw its own “inferences.”

“The only situation where the feature would have been activated is in the case of a stolen, missing or lost laptop,” Young said. “There’s never been any scenario used for any purpose other than that.”

Lawyers for the student did not return phone calls and e-mails for comment. The Associated Press reported late Friday the FBI was probing the allegations. (more…)

Thwart robbers with an old smoke alarm.

Tuesday, March 2nd, 2010

[Anders] tipped us off about his hack that re-purposes a smoke alarm as a burglar alarm. Unfortunately, he came home in the middle of a burglary but wanted to be ready the next time someone tries to break in. By cleverly patching into the test button on an old smoke detector he created a circuit-trip alarm. One side of each piece of wire is secured to the frame and jam of a window. A paper clip completes the circuit by pinching the two bare conductors. If the window is opened the connection is lost and the alarm sounds.

We see a few problems with this system. First off, never hack your ONLY smoke detector, you are putting lives at risk by doing so. But [Anders] says he’ll have a replacement detector and since these things need to be replace every ten years or so, chances are you can find an old one kicking around. We’d recommend disguising the case so that people aren’t confused about it being a smoke detector. Secondly, he’s mounted the alarm right in the window frame so most likely an invader will just smash the thing to bits.

Anyway, it’s still an interesting reuse of these ubiquitous, and life-saving, devices.

Python IR tracking for the handicapped

Tuesday, March 2nd, 2010

[Techb] had a friend who was paralyzed after an accident and could no long use a computer. He rigged up an amazingly simple mouse interface using python to implement infrared tracking. The controller was built from an old hat by adding an IR LED and wireless mouse modified so that the button could be clicked by the user’s mouth. A webcam with exposed film used as a filter can track the IR LED and take input from the wireless mouse buttons.

This setup, which draws inspiration from Wii Remote white boards,  is much simpler than the Eyewriter (and doesn’t shine an IR LED into your eye). Although [Techb] wants to add facial recognition to the system, there’s something to be said for such a simple implementation.

RFID tracking system

Wednesday, February 24th, 2010

This is a working tracking system using RFID tags built by Nicholas Skinner. The system’s tags operate in the 2.4 GHz band and are used to track either people or assets. The readers are on a mesh network and can triangulate the location of any tag for display on a map. His system is even set up to show the travel history of each tag. [Nicholas] shared every detail in his writeup including some background about available hardware options and how he made his final decisions on what devices to use for the job. His conglomeration of software that ties the whole project together is also available for download.

Facial recognition brings online stalking to the real world

Wednesday, February 24th, 2010


What if you could point your cellphone’s camera at someone’s face, and then know that person’s name, schedule, profile, and latest tweets? That’s the promise of Recognizr, an Android app prototype using a 3D model to recognize facial features, find a match on its server, and then superimpose that person’s social networking preferences around his or her face.

Created by Swedish mobile software designers The Astonishing Tribe, it’s astonishing indeed. Problem is, unless everyone opts into this service, it won’t be particularly useful. However, if it were ubiquitous, imagine how easy it would be to act like you’re using your cellphone, but actually be finding out that person’s name standing in front of you — while you snoop around her Facebook profile.

Finally, Facebook stalking finds its way to meatspace! On a smaller scale, this could be useful at, say, a trade show or a party. Electronic nametags would be lots of fun, if everyone would submit to them.

British police want UAVs to watch civilians during the 2012 Olympics

Friday, January 29th, 2010

550x360-32929.jpg

In what’s sure to be a popular idea, Britain’s Kent Police Department wants to use unmanned aerial vehicles to keep tabs on the massive crowds during the 2012 Olympic Games in London. Now, before you start thinking that Ministries and doublethink are soon to follow, Olympic games mean a large influx of people to keep track of, and that means spreading security pretty thin.

Evidently UAV monitoring already has a precedent in Britain through the South Coast Partnership, which uses UAVs to patrol the country’s southern coast. UAVs aren’t yet cleared to fly the skies over London with other manned aircraft, however.

From Pop Sci:

So far, the Civil Aviation Authority (CAA), Britain’s equivalent of the FAA, has not cleared UAVs to fly in the same airspace as manned aircraft. However, the Kent police department has petitioned the CAA to expedite the licensing processes so the police operated UAVs can take to the sky by the time the Olympics starts.

If it goes through, it’ll be interesting to see if it’s only a temporary measure for the Olympics, or if that level of surveillance remains in place in a city already dominated by CCTV security cameras.

silverstat 7

Well isn’t this the prettiest thermostat you’ve ever seen? It’s the SilverStat 7 from SilverPAC, the same folks who created that elaborate Evolution 5500 remote control we showed you a few weeks ago. This is the smartest thermostat yet, communicating with utility companies, eliminating that pesky meter reading chore they must do every month. It keeps tabs on your energy usage, and similar to that TED 5000 system we reviewed last month, it helpfully displays to you in pretty graphics exactly how much power you’ve been sucking lately.

This is not just for the benefit of the energy mongers and treehuggers. Its Wi-Fi interface and 7-inch display makes it a highly capable network player, showing streaming photos, music and content from your PC or the Internet. It has built-in speakers, Z-Wave home automation so you can manage your lighting and appliances, FM radio, and heck, you can even check your email on the thing.

Look at the gallery full of screenshots of all the various functions this spectacular thermostat can perform. Oh yeah, one more thing: It’s a seven-day programmable thermostat that controls your heating and air conditioning. The wizards at SilverPAC aren’t talking price yet.

Blue Force Tracking

Wednesday, October 21st, 2009

Tank_traning.jpg

Blue Force Tracking is a United States military term used to denote a GPS-enabled system that provides military commanders and forces with location information about friendly (and despite its name, also about hostile) military forces.

In military symbology, the color blue is typically used to designate friendly forces while red is used for enemies, and green or yellow are used for neutral forces.

Blue Force Tracking systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually in the form of a GIS, that plots the BFT device on a map. The system displays the location of the host vehicle on the computer’s terrain-map display, along with the locations of other platforms (friendly in blue, and enemy in red) in their respective locations. BFT can also be used to send and receive text and imagery messages, and Blue Force Tracking has a mechanism for reporting the locations of enemy forces and other battlefield conditions (for example, the location of mine fields, battlefield obstacles, bridges that are damaged, etc.). Users will include the United States Army, the United States Marines Corps, the United States Air Force and the United Kingdom. Recently, the United States Army, the United States Marines Corps have reached agreement to standardize on a shared system, to be called “Joint Battle Command Platform”, which will be derived from the Army’s FBCB2system that was used by the United States Army, the United States Marines Corps, and the Army of the United Kingdom during heavy combat operations in Iraq in 2003.
