Chaos Computer Club using fingerprint copy to bypass Apple TouchID

Here is a really cool post by the Chaos Computer Club found on Dr. Chaos’s blog (but they are not associated with each other) about bypassing Apple TouchID. For those watching the new iPhone releases, this is a major feature from the iPhone S. The original post can be found HERE

First, the fingerprint of the enrolled user is photographed with 2400 dpi resolution. The resulting image is then cleaned up, inverted and laser printed with 1200 dpi onto transparent sheet with a thick toner setting. Finally, pink latex milk or white wood glue is smeared into the pattern created by the toner onto the transparent sheet. After it cures, the thin latex sheet is lifted from the sheet, breathed on to make it a tiny bit moist and then placed onto the sensor to unlock the phone. This process has been used with minor refinements and variations against the vast majority of fingerprint sensors on the market.
