This home science project costs about £20. Take a finger and make a cast with the moulding plastic sold in hobby shops. Then pour some liquid gelatin (<A href="http://www.screenface.com/NewProdDets.asp?Products_Action=Find('Productid','1295')&Products_Position=FIL:ContentsHdg=%27SpecEffectsSFSpecialEffects%27ORD:ABS:9KEY:1295PAR:">ordinary food gelatin</A>) into that mould and let it harden. Stick this over your finger pad: it fools fingerprint detectors <A href="http://web.mit.edu/6.857/OldStuff/Fall03/ref/gummy-slides.pdf">about 80% of the time</A>. The joy is, once you’ve fooled the machine, your fake fingerprint is made of the same stuff as fruit pastilles, so you can simply eat the evidence.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.badscience.net/2007/11/make-your-own-id/"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/www.badscience.net/img/DD868A0F-4A7E-4C3F-BFA5-687AACEAD622" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.badscience.net/2007/11/make-your-own-id/"><P>But what if you can’t get the finger? Well, you can chop one off, of course - another risk with biometrics. But there is an easier way. Find a fingerprint on glass. Sorry, I should have pointed out that every time you touch something, if your security systems rely on biometric ID, then you’re essentially leaving your pin number on a post-it note.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/7C2AD796-6965-4D43-A6E9-9EC6667DAA0D/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
