http://en.wikipedia.org/wiki/Christopher_Paul_Neil
He was identified using image technology and arrested in a world wide search

The "swirl" operation allegedly used by Neil to disguise his face in photographs is in theory lossless: that is, information about the original image is not lost and can be perfectly restored from the altered version. In practice both resolution and colour depth limitations in a digital image make the operation slightly lossy, but it is reversible by applying the same operation with opposite rotational direction and the same intensity.
Although exact steps may vary, this disguise and restoration can be made by following these steps:

Apply the twirl filter with x degrees settings to the picture. This should distort the picture.

To un-distort, apply the twirl filter with -x degrees setting. Alternatively, one can flip the picture and apply the first twirl filter (with x degrees) again.
