70% accuracy in face recognition app - so what happens to the 30% who might be falsely recognized as criminals ....

when this deviously evil app is bought into play by the law enforcement bodies of our world gone mad?
 
I looked in my crystal bowl and I can see this "thing" being used at airports, stadiums, theatres or whereever people gather. This would have the added incentive of giving the bullies making use of such contraptions, to further humiliate the sheeple and to bring the not-so-sheeple in line with the rest.

It will be easy to pick someone from the crowd and take him aside based on this 70% "accuracy" which might make the suspect "victim" miss his flight or his game. Hours later, or days later or perhaps even weeks or months later, the "suspect" is indeed found to have been nothing but a victim of this draconian app and viola the law enforcement bullies will have a tonne of lawsuits dropped on them.  Nice, eh?

Face recognition app taking Russia by storm may bring end to public anonymity

FindFace compares photos to profile pictures on social network Vkontakte and works out identities with 70% reliability

If the founders of a new face recognition app get their way, anonymity in public could soon be a thing of the past. FindFace, launched two months ago and currently taking Russia by storm, allows users to photograph people in a crowd and work out their identities, with 70% reliability.....

....But the FindFace app is really just a shop window for the technology, the founders said. There is a paid function for those who want to make more than 30 searches a month, but this is more to regulate the servers from overload rather than to make money. They believe the real money-spinner from their face-recognition technology will come from law enforcement and retail.....

Revealed: How facial recognition can expose your life to strangers 

A facial recognition app that can work out the identities of strangers in a crowd by matching their faces with profiles on social media is taking Russia by storm.

In just two months FindFace has gathered 500,000 users who have run nearly 3 million searches, according to its founders.

The technology gained international attention when a photographer used it to create an art project that revealed just how much information strangers can gather about you with a picture of your face.

Russian photographer Egor Tsevtkov wanted to know how much personal data he could find out about complete strangers on the underground. With this idea in mind he photographed a selection of strangers, and used a free facial recognition software with terrifying results. 

The software he used is a website called Find Face, which lets users look up people online using a photo, and accurately matches them up with a Facebook profile, based on their faces.

"I learnt a lot about a person's life without any contact," said Tsevtkov. "I felt slightly uncomfortable.".....
