The premise of the story hinged on the afore-mentioned corneal transplant technology that then led on to Iris Recognition.
This allows for Jack Petachi’s replacement (they’ve turned him into a herion addict you see, so they can get him to do anything – especially as they use threats on his sister as back-up bribery), to fool the scanner into believing he is actually the President of the United States of America and it is okay to swap the dummy nukes for real ones.
All very cunning.
As opposed to fingerprints that wear with time, as an internal organ, the eye has long been considered ideal for identification purposes. It is also relatively flat and easy to photograph, so it is unsurprising that such recognition technology was developed.
The biometric authentication process uses pattern recognition of a person’s eye. These complex patterns and shapes are unique to an individual.
In 1987 two Ophthalmology Professors; Leonard Flom and Aran Safir were issued the first patent on Iris Recognition Technology.
The technology moved at a pace and even Passports now include the technology. Indeed, millions of people worldwide have had their iris’ recorded for future use by evil overlords and dastardly governments. Or something like that.
Back in 1983 however, this technology would have been considered supremely cutting edge.
In 2005 the UK Border Agency began to introduce Iris Scanning at its airports. You now cannot enter the United States without having your biometrics scanned. Of course, no-one tells you what they intend to do with this information, but we all have to get on with it.
