Gummi bears and fingerprint sensors

With biometric fingerprint sensors becoming more commonplace than ever the security of this technology has been touted as unbeatable and very reliable. Enter Tsutomu Matsumoto, a Japanese cryptographer, who has demonstrated how easily fooled these sensors can be.

Using gelatine, a common ingredient in Gummi bears and other candy, Mr. Matsumoto created a fake finger mold out of plastic which he used to fool fingerprint sensors four out of five times. Using readily available components he found he could reliably fool eleven commercially available fingerprint biometric systems.”The results are enough to scrap the systems completely, and to send the various fingerprint biometric companies packing,” said Schneier in yesterday’s edition of his Crypto-Gram newsletter, which first publicised the issue. ┬«Thanks to The Register for this story.
