The Hush Post: Facebook has admitted that the phone numbers that its users provide are being used to target them with ads.
“We use the information people provide to offer a better, more personalised experience on Facebook, including ads,” a Facebook spokesperson said. A technology news website TechCrunch published a report quoting FB spokesperson on Thursday.
The social network uses a phone number that users provide for two factor authentication (2FA). It is a security technique that provide a second layer of authentication to help keep accounts secure.
“We are clear about how we use the information we collect, including the contact information, ” the Facebook spokesperson said. “You can manage and delete the contact information you’ve uploaded at any time,” he added.
However, the spokesman said that users can opt out of this ad-based repurposing by not using phone number based 2FA.
Facebook confirmed the use of users’ phone number for targeting ads. The report by Gizmodo, an online media company and blog network, said that research work was carried out by academics at two US universities. They found that social network uses pieces of personal information. But, this info was not been shared by individuals but was collected from contact books of other people.
The findings of the study suggest that Facebook uses “shadow contact information” to make money through advertising.
