| 48 | The process described above proved to be somewhat unreliable as the | ||
| 49 | depth of the ridges created by the toner was a little too shallow. | ||
| 50 | Therefore an alternative process based on the same principle was | ||
| 51 | utilized and has been demonstrated in an extended video available | ||
| 52 | [here](http://www.heise.de/video/artikel/The-iPhone-5s-Touch-ID-hack-in-detail-1966044.html "Refined TouchID hacking process"). First, | ||
| 53 | the residual fingerprint from the phone is either photographed or | ||
| 54 | scanned with a flatbed scanner at 2400 dpi. Then the image is converted | ||
| 55 | to black & white, inverted and mirrored. This image is then printed onto | ||
| 56 | transparent sheet at 1200 dpi. To create the mold, the mask is then used | ||
| 57 | to expose the fingerprint structure on photo-senistive PCB material. The | ||
| 58 | PCB material is then developed, etched and cleaned. After this process, | ||
| 59 | the mold is ready. A thin coat of graphite spray is applied to ensure an | ||
| 60 | improved capacitive response. This also makes it easier to remove the | ||
| 61 | fake fingerprint. Finally a thin film of white wood glue is smeared into | ||
| 62 | the mold. After the glue cures the new fake fingerprint is ready for | ||
| 63 | use. | ||
