Facebook also says it uses the data to improve its own ads and identify bots and bad actors.
The decision by the social media major came after the controversy of data leaks in the past by Facebook, which allegedly influenced the election in the USA in favour of Republican party-led by Donald Trump.
On Monday, US district judge James Donato ruled the suit could go ahead, representing all IL users "for whom Facebook created and stored a face template after 7 June 2011".
Many websites and apps use Facebook services to make their content and ads more engaging and relevant.
Privacy concerns have swamped Facebook since it acknowledged last month that information about millions of users wrongly ended up in the hands of political consultancy Cambridge Analytica, a firm that has counted US President Donald Trump's 2016 electoral campaign among its clients.
The company said it does not use the data to target ads, except those inviting people to join Facebook.
Trump gives full pardon to lawyer who leaked Central Intelligence Agency agent's undercover identity
Asked if a pardon would be about Comey, Conway said no. "It's not about me, it's absolutely not about "Scooter" Libby", she said. Trump has termed Mueller's probe a "rdquo & witch search; and Russian Federation and also he have denied any wrongdoing".
Facebook has released more information on the social media platform's tracking of users off-site, after its CEO, Mark Zuckerberg, failed to answer questions about the process from U.S. politicians and as the company prepares to fight a lawsuit over facial recognition in California. "This is because other apps and sites don't know who is using Facebook", Baser said in his post as part of Facebook's Hard Questions series. "We can also use the fact that they visited a site or app to show them an ad from that business - or a similar one - back on Facebook".
"If I'm not a Facebook user, I ought to have a right to know what data Facebook has about me", Froomkin said. Facebook allows its users to adjust their News Feed and ad preferences for a more secure and personal experience. While those types of information are mutable - even Social Security numbers can be changed - biometric data for retinas, fingerprints, hands, face geometry and blood samples are unique identifiers.
The blog post states that it is not just Facebook that collects such data.
As Facebook, other social media sites and users themselves put greater value in trusted sources, musicians and labels that communicate in a straightforward and honest manner will be front an center once again, replacing the trolls, bots, and spammers that users and the social channels themselves are done with. Following that link, users will be directed to a section where they can see which apps and websites they have used Facebook to log into, and remove any they no longer want connected to their account.
The "tag suggestions" feature, involves Facebook running facial recognition tech on uploaded photos to match them with other users automatically.
"This kind of data collection is fundamental to how the internet works". "While there is no maximum, high impact bug reports have garnered as much as $40,000 for people who bring them to Facebook's attention", Greene said.
Over the last couple of weeks, Facebook has been trying to fix its image and has been doing this by offering a number of explanations on how it collects and uses data.
