Well, unless it looks disgusting.
Or what about criminals giving themselves an eye infection to change their scan and by[ass a watch list?
So if only iritis inhibits the scan, and that in only 5 of every 24 cases, and only 1 in 1000 have iritis, then that just means a whopping 5 in every 24,000 people would require manual screening to determine identification. I don't see the problem here.
The last truly effective security mechanisim I am aware of is a machine dubbed the enigma, its code was broken only through capture of one of thier crypto machines. Another one that strikes my mind (i.e. WWII) is the Native American code, which was never broken - but not because it was impossibe, but because it was based on human intel.
There is today, no such thing as 100% foolproof integrity of any system.
Foolproof systems?
I cannot say what would happen in the world tomorrow if such a questionably reliable system were to be put into place, But it generates fear within me, because that is power in the hands of the few that control it.
Gaaaaaaaaaaah that picture freaked me out.
There used to be a field of science or pseudo-science that beleived that the Iris reflected major illness anywhere in the body. If there is any truth to that it’s not just eye illness that could destroy your identity, it’s any illness.
Eye scanners are not the be all and end all to identification in an airport. A bad guy would also have to have a fake passport of someone who has never traveled through the airport or any other airport that shares their eye scan data. Furthermore, in the future they are likely to have facial recognition capabilities which would give them an immediate match to a database of known bad guys.
