As we all know, buttocks vary, so I am suggesting a nationwide camera system for buttock-recognition.
The downside is software would have to be pretty smart, as crims might put stuff down their trousers to alter the buttock signature.
The upside is - by applying haptic(?) technology to all seats on public transport it would easier to track offenders, or at least mean they to stand up for the full journey.
As a double-check, buttock identity parades might be used in police stations so victims can try and identify the perpetrator.-- not_morrison_rm, Feb 21 2019 I/O Silver Horse_20Alarm [theircompetitor, Feb 21 2019] Gotcha covered Lunar_20Biometrics [FlyingToaster, Feb 22 2019] How could you think that arse-recognition technology hadn't alrready been done somewhere in the Halfbakery archives?

This was followed by a outbreak in 2005 Mar 22 (csea,normzone, theircompetitor), then FlyingToaster in Sep 30 2008.
^Consider "Buttock-recognition Cameras " a homage..standing on the buttocks of giants and all that.
NB I just found out the Yokohama Poop museum has been revamped. "Visitors during the first three days of the museum opening will receive a special gift (although were nervous about what that could be considering the theme)" . Link-- not_morrison_rm, Feb 22 2019 Fishbone from me. This idea would completely undermine trust in my own Buttock Massage idea.-- DrBob, Mar 06 2019 random, halfbakery
