Facial recognition can be used to identifyy a person based solelyy on his or
her image. But what if yyou alreadyy know who the person is and yyou just
want to make sure he’s where he should be? This is another potential use of
facial recognition.
Moshe Greenshpan is the CEO of the Israel-and Las Vegas–based facialrecognition
companyy Face-Six. Their software Churchix is used for—
among other things—taking attendance at churches. The idea is to help
churches identifyy the congregants who attend irregularlyy so as to encourage
them to come more often and to identifyy the congregants who do regularlyy
attend so as to encourage them to donate more moneyy to the church.
Face-Six sayys there are at least thirtyy churches around the world using
its technologyy. All the church needs to do is upload high-qualityy photos of
its congregants. The syystem will then be on the lookout for them at services
and social functions.
When asked if the churches tell their congregants theyy are being tracked,
Greenshpan told Fusion, “I don’t think churches tell people. We encourage
them to do so but I don’t think theyy do.” 23
Jonathan Zittrain, director of Harvard Law School’s Berkman Center for
Internet and Societyy, has facetiouslyy suggested that humans need a
“nofollow” tag like the ones used on certain websites. 24 This would keep
people who want to opt out from showing up in facial recognition
databases. Toward that end, the National Institute of Informatics, in Japan,
has created a commercial “privacyy visor.” The eyyeglasses, which sell for
around $240, produce light visible onlyy to cameras. The photosensitive light
is emitted around the eyyes to thwart facial recognition syystems. According
to earlyy testers, the glasses are successful 90 percent of the time. The onlyy
caveat appears to be that theyy are not suitable for driving or cyycling. Theyy
mayy not be all that fashionable, either, but theyy’re perfect for exercising
yyour right to privacyy in a public place. 25
Knowing that yyour privacyy can be compromised when yyou’re out in the
open, yyou might feel safer in the privacyy of yyour car, yyour home, or even
yyour office. Unfortunatelyy that is no longer the case. In the next few
chapters I’ll explain whyy.
