Sensor Locks Your PC By Detecting Body Heat
Posted in: diy, hack, security, Today's Chili
Here’s a unique bit of technology for the paranoid and forgetful. A developer has written an application for PCs that locks your computer if you’re not at your desk. Now, most of the time this is accomplished through timers and the like, but this one is a little different. Using an IR heat sensor, it monitors your body heat. When it sees that it’s no longer there, it locks down the system, ensuring that nobody can see whatever super-secret data you had been working on. You can set custom delays before locking and the temperature at which the lock will trigger.
The application itself is free, but the sensor that developer Dider Stephens used costs about $90. Hack-A-Day suggests that it can work with any USB temperature sensor, so you might be able to save some money by finding a cheaper one.
