The "off-the-shelf"-software mentioned in the articles which was used for this hack is a commercial offering called VeriFinger costing almost 400.- EUR (see also http://download.neurotechnology.com/Ver ... -04-17.pdf).
The same thing should be possible with ImageMagick, I'm pretty sure. Can we proof it? Can we help to make IT more safe by showing that the idea biometric authentication schemes are br0ken in many ways?
Look at the fingerprint photo below:
The source of this photo is this website: http://www.pbs.org/wgbh/nova/next/tech/ ... be-hacked/
My question is: how can we, with ImageMagick, convert this photo to a black+white only representation of a fingerprint? I guess a simple, single command line will not work, because:
- different areas of the image need different image setting parameters
- there is a special challenge in that the embossments are very "shiny" because of skin fat in some areas, and rather dark in the shadows
- the photo is taken from an angle and the resulting image should probably account somewhat for some additional rotation ins space.
I think a script may be successful if it knows to apply a clever combination of the new '-canny' edge detection with some variants of '-*contrast*' and '-threshold' improvements.
