Smart Holograms Used as Biosensors
Roland Piquepaille writes "In this short article, eWEEK writes that the next generation of biosensors will consist of small holograms costing only fractions of a cent. Prototypes developed by a U.K. company, aptly named Smart Holograms, include contact lenses that monitor glucose levels or thin badges that detect alcohol levels. Not only these holograms used as sensors will be cheap to produce, they'll also require less training for nurses or police officers. This is because these holograms can be designed to show results graphically, such as morphing into an image of a green car if someone subjected to breath analysis is sober and can drive. Read this overview for other details and an illustration showing how to create a sensor hologram."
Humans are the best biosensors yet made, with dogs perhaps a close second. Intelligent, intuitive, experienced humans can scan someone's face, question them, trip them up in inconsistent statements, and otherwise sniff out intruders and frauds. Dogs can literally smell or otherwise somehow sense nervousness in people and make excellent guards. They ID people by scent and they don't forget scents quickly.
If we focussed on human intelligence we would perhaps be able to avert more catastrophes, such as the series of missteps that allowed the 9/11 hijackers to get on board their planes despite some rather suspicious behavior.
Computers are always going to be only as good as the programs that control them, and there are always going to be workarounds for people clever enough to find them. Insiders will create back doors in biosensor systems, or they will sell passwords to outsiders. A team of Japanese researchers already cracked a fingerprint biosensor a couple of years ago, so where's the security in using one? I would imagine even a DNA sample can be faked; just get someone's DNA, replicate it in a test tube using E. coli, and coat your hands with it. Standard laboratory biology.
No one can steal your identity at the low-tech neighborhood store where you shop once a week and the clerks know you (if only this were always the case). The humans at the store will look at your credit card, then at the face that does not match yours, and they'll go in the back and call the police. A machine will simply pass the buck, leaving the owner to dispute the theft with the credit card company.
The Israelis for decades have relied on human intelligence and it has stood them in good stead, with zero airline hijackings. They have very smart people who look at everyone before they board. We in the U.S. are just beginning to wake up to this level of need and we have a lot to learn.
it's = "it is"; its = possessive. E.g., it's flapping its wings.
