FB continua a usare i propri utenti cone cavie inconsapevoli per esperimenti... Alberto <https://www.businessinsider.com/facebook-built-internal-facial-recognition-c...> Facebook once built an internal app that let employees identify people using facial recognition and their phone cameras. The app, which was developed between 2015 and 2016, utilized Facebook's vast collection of user identities to automatically recognize the person at whom the phone's camera was pointed. The app was not released publicly, and Facebook told Business Insider that it worked only on company employees and any of their friends who opted in to the social network's facial-recognition system. "As a way to learn about new technologies, our teams regularly build apps to use internally. The apps described here were only available to Facebook employees, and could only recognize employees and their friends who had face recognition enabled," a Facebook spokesperson said. The existence of the app illustrates how Facebook has been quick to experiment with technology that could have significant societal implications. Facebook once built an internal facial-recognition app that allowed employees to identify people by pointing their phone cameras at them. The app, which was developed by Facebook employees between 2015 and 2016 and tested internally, relied on information from the social network's vast collection of user-uploaded photos and facial-recognition data to identify people in real life within seconds, sources told Business Insider. It was shown off at an internal all-hands meeting in 2015, one source said, and was presented as an "example of future innovations" that Facebooks' technology and data could enable. A second source said that in 2016 a beta version of the app was made available for download to Facebook employees that used a smartphone camera to identify anyone for whom the social network had enough data — regardless of whether or not they were a Facebook employee. It was subsequently restricted to identify only people recognized as Facebook friends of the app user (still regardless of whether or not they were an employee), and they used the app on their friends only after that change was made, they said. A Facebook spokesperson denied that the app could ever identify strangers who didn't work at Facebook, saying that it was able to recognize only the faces of Facebook employees and of Facebook friends of the user who had enabled the social network's facial-recognition system on their accounts. The app was clearly in its early stages and had a basic camera interface, a source said. When pointed at someone, it would take about three to five seconds to recognize them, and then displayed their Facebook name and profile picture. For years, Facebook has used facial-recognition technology to identify the subjects of photos uploaded to its core social network and recommend "tagging" them — but the version available to consumers has been applied only to photos and never for real-time real-world face recognition. In September, Facebook said it would change to make facial recognition an opt-in feature, rather than assuming by default that users consent to having their faces scanned. The existence of the experimental app, which has not been previously reported, highlights Facebook's willingness to experiment with technologies with major societal implications. And it raises questions about the $564 billion company's historic approach to privacy and consent, and its handling of users' data. A Facebook spokesperson said the company routinely builds experimental apps internally, and that the facial-recognition app has since been discontinued. "As a way to learn about new technologies, our teams regularly build apps to use internally. The apps described here were only available to Facebook employees, and could only recognize employees and their friends who had face recognition enabled," said the Facebook spokesperson in a prepared statement.
