Guinea-Bissau: Olympic Committee election process worries international bodies
UK data consultancy Cambridge Analytica (CA) may have accessed the personal data of as many as 63,080 users in Portugal of the online social network Facebook, according to the US company.
In information released by the company, Facebook said that 15 users in Portugal downloaded the app ‘thisisyourdigitallife’ that CA used to obtain data from participants.
The vastly greater number of users potentially affected in terms of access to their data arises from the “expansive methodology” used by Facebook in mimicking CA’s practices, which included using data on the Facebook ‘friends’ of participants who downloaded the app.
“We carried out our own internal analysis to determine the number of people potentially targeted,” Facebook said. “We used an expansive methodology – this is our best estimate of the number of people who installed the app, as well their friends whose data may have been accessed.”
In a teleconference with various journalists, the co-founder and CEO of the company that owns Facebook, WhatsApp and Instagram, Mark Zuckerberg, said that CA is believed to have accessed the data of 87 million users worldwide.
Facebook has been the focus of international controversy in recent weeks, after the scale of the data collected and used by CA emerged. CA is alleged to have used the information of millions of Facebook users, without their consent, to develop online campaigns to win over US voters for the then Republican candidate, now US president, Donald Trump.
