Brasilia – If you are a social network user Facebook, you will hardly see in your timeline the publication of a friend with two photos, one from 2009 and the other from 2019 The game, nicknamed "the 10-year challenge" (or # 10yearchallenge, in the English word hashtag), has since become the main "game" of the moment on the platform.
The challenge has won every Adaptation forms, people posting photos by comparing their images of the last ten years to a hook to compare artists, politicians, places and situations.The same has become a discussion tool ranging from the evolution However, the popularity of the challenge also sparked the debate of experts in computer security and personal data protection Kate O'Neill, a consultant in digital author of books on naked technologies have asked questions about social networks. Wired, the world's largest technology magazine, emphasized how published images can not be used to "train" the Facebook System that performs facial recognition of users.
Automatic Marking
When an image is published, the social network performs this identification. This feature appears, for example, when she "suggests" tagging the user or her friends on photos.
However, the platform began to perform these "badyzes" on all images and to "warn" the person when a photo was published. The argument was that the user was more in control of the content on the site. However, the deployment of this feature has been criticized. Facebook reacted and configured the feature as an option that can be disabled by the user.
Recognition, even with this tuning device, is performed via a technology that "learns" how to improve this procedure as it is received. more data or more photos. This has led Oneil and other experts to question how such images from 10 years ago could "feed" the Facebook database and "train" their systems.
"This can happen." This is a very difficult task, "said the privacy researcher and professor at the consulting firm DataPrivacy Brazil Renato Leite.
With the Doubts reverberate, Facebook is positioned on the subject. "This is a meme created by users of our platforms and that spontaneously activated itself." Facebook has not launched this wave and generally uses photos already present on Facebook As a reminder, it is worth remembering that Facebook users can choose at any time to leave facial recognition active or not. "
However, Leite declares that the photos posted by users, at the time (10 years ago), were not necessarily available or had been published on the social network. "If the photos are displayed on the timeline and Facebook does the badysis, because that's part of the algorithm, they will benefit." Although Facebook claims that it is a third-party initiative, the key question is whether the company actually uses the photos to form their algorithms with these metrics, said the Professor
This doubt, adds the expert, raises a reflection on the need for greater transparency on the part of society vis-à-vis its users so that they know how the images are used and for what purposes.It adds that the impact exceeds the users themselves, because the systems even map people outside the social network when a photo is published, which generates a unique identification or "ghost profile".
Creating a Discussion
Policy badyst for the digital rights organization Eletronic Frontier Foundation, Veridiana Alimonti, believes whether society benefits from gambling or not, ntroverse surrounding this challenge has been beneficial to the debate about the risks of
His organization, EFF, has conducted studies highlighting threats such as the malicious use of biometric data, sharing without transparency between public authorities and private companies, or even to harm people by mistaken identification.
Veridiana thinks that such debates can help the citizen to become aware of how he / she is on social networks like Facebook. "If this discussion draws attention to this, let us warn about how people treat platforms in relation to the information they have and their uses," he said.
