Once again science fiction has become science fact, facial recognition technology is no longer confined to TV dramas such as CSI, it is being used by the FBI, Interpol and law enforcement agencies worldwide.
The technology is following the arc of all new tech, at first it is cumbersome and expensive, but as the months and years pass, so to does the software and hardware improve in quality and reduce in price, until it is cheap enough to give to a consumer on a smartphone or laptop.
However it is not the consumer side of this technology that we have potential worries about, it is its use by law enforcement that could bring about a worrying state of affairs. A Brave New World in which convictions are made in total certainty, ignoring the natural fallacies that come with such a technology.
Only As Good As Your Input
In 1986 in Leicester (pronounced less-ter) England, the biologist Alec Jeffreys made history by using DNA evidence in court to confirm the validity of a rape-murder suspect. Shortly after in 1987, Tommie Lee Andrews became the first person in America to be convicted using DNA evidence, and so began its acceptance as credible evidence in courtrooms across the globe.
Gaining convictions by DNA became the holy-grail for law enforcement agencies, seeing as our DNA is unique in each one of us that is not a maternal identical twin below a few days old (DNA of identical twins can differ very slightly if they live different lives).
However after some time we realised that genetic evidence is not always infallible. For a start if the lab taking the sample has not collected it in a certain way there is room for error. And as David Butler found out in 2012, there are other ways for your DNA to end up in a crime scene.
Mr Butler was wrongly arrested on suspicion of murdering Anne Marie Foy in the UK in 2005, despite CCTV evidence placing him at the scene of the crime being completely disproved. The confidence in DNA evidence was such that the trial went ahead anyway. It was only when a forensic expert showed that Mr Butler's skin condition led him to shed more genetic material than the average person, coupled with him being a taxi driver and handling money all day, was he acquitted.
Unfortunately Ms Foy's murderer has never been caught and the case remains open. The case highlights the dangers of having a 'magic bullet' of evidence to convict. DNA is unique, ergo if your DNA is found at a crime scene you are guilty and damn any other explanations why. This line of reasoning cost David Butler 8 months of his life in a remand prison (jail) and probably gained him a fair amount of stigma and suspicion.
The New Digital DNA?
As companies like FindFace, Amazon, Microsoft and others develop and sell their facial recognition tech to the FBI and law enforcement agencies around the world, there is a danger that we are creating an over-reliability on the new magic bullet.
Facial recognition would perhaps be less fallible if the initial samples were taken from actual live faces, but of course this is rarely the case. The FBI for instance use the 400 million photographs they have on file from passports and drivers licenses.
This means that the quality of the photograph comes into play; how long will it be before somebody who looks like the photograph of a criminal is convicted?
Safeguarding The Future
Of course we all want to be safe, when we use airports or crowded places we want to know that terrorists and criminals are being monitored and thwarted. What we don't want is a situation whereby we are all considered terrorists until proven innocent.
A situation such as that could thrust us into the fantasy world of Minority Report, whereby potential criminals are arrested before they have even committed a crime.
We must be careful that no matter how great and seemingly infallible a new technology is, that we don't give it magic bullet status. Otherwise we may find that we use it to shoot society in the foot.
WHAT DO YOU THINK OF FACIAL RECOGNITION TECHNOLOGY; IS IT HARMLESS FUN AND A GOOD TOOL TO FIGHT CRIME? OR PERHAPS AN IMPEDING PROBLEM THAT WILL BLOW UP IN OUR FACES?
