Cheap(er) biometric gun safe

[Greg] sent in his biometric pistol safe lock. He keeps his guide light on details so not every Joe can crack the system (there is a thread to sift through if you really wanted to), but the idea runs fairly simple anyway. [Greg] took an old garage door opening fingerprint scanner and wired it into a half broken … Read the rest

Pulse Oximeter

[Mike] is building his own Pulse Oximeter which uses light to measure the oxygen saturation in blood. One collateral benefit of this measurement is that pulse rate can be calculated from the same data. The parts used for the detector include a red LED, infrared LED, and a TSL230R light intensity measuring chip. As explained in the video above, each … Read the rest

The Narcisystem

biometric

The Narcisystem is part of an art display where [Eric] strapped himself to as many biometric sensors as he could. The core of the system was a Funnel IO which includes an Arduino, Xbee plug, and LiPo charging circuit. It was collecting data from a heart rate monitor, an EEG, a breathalyzer, compass, and an accelerometer. This data … Read the rest

Biometric locks turned trojan


In the same vein as our recent Defcon article on biometric cloning, White Wolf Security has released this article about turning a biometric door lock into a trojan. They note that there are many common ways to break into one, from harvesting fingerprints to using gummy bears to fake a finger. This hack involves having full access to … Read the rest

Defcon 16: Biometric cloning


One of the more novel talks we saw at Defcon was [Zac Franken] presenting on access control systems. He covered several different types, but the real fun was his live demo of bypassing a hand geometry scanners like the one pictured above. With the help of two assistants, 4 pounds of chromatic dental alginate, and 5 liters of water, … Read the rest
