Facebook to alert users affected by data leak
Written by Dan Williams on 9th April 2018
Facebook has revealed that it will begin to alert those whose personal information may have been shared with the Cambridge Analytica as part of the data mining scandal.
Those that may of had their data improperly shared with the British firm will receive a detailed message at the top of their news feed, the social network said.
The majority of those whose information was shared with the data analytics company – around 70 million – are in the US. But more than one million people in the UK, the Philippines and Indonesia were also affected, Facebook said.
All 2.2 billion Facebook users will receive one of two notices titled “Protecting Your Information” with a link to see the apps they use and the information they have shared with those apps. They will have the option to turn off apps individually or shut down third-party access to their apps entirely.
One of the notices will tell Facebook users whether their data may have been shared with Cambridge Analytica.
“As part of this process we will also tell people if their information may have been improperly shared with Cambridge Analytica,” said Facebook’s chief technology officer Mike Schroepfer in a blog post.
It comes after the founder of the social media giant Mark Zuckerberg admitted he made a “huge mistake” in failing to take a broad enough view of what Facebook’s responsibility is in the world.
Scores of people claimed to be shutting down their accounts as details of the data leak emerged.
Mr Zuckerberg said Facebook came up with the 87 million figure by calculating the maximum number of friends that users could have had while Mr Kogan’s app was collecting data.
The company does not have logs going back that far, he said, so it cannot know exactly how many people may have been affected.
Cambridge Analytica said in a statement on Wednesday that it had data for only 30 million Facebook users.
The company has denied misusing data.
