Online privacy

Facebook is curbing the information that it exchanges with companies that collect and sell consumer data for advertisers. The measures affect a group of so-called data brokers such as Acxiom Corp. and Oracle Data Cloud, formerly known as DataLogix, that gather shopping and other information on consumers that Facebook for years has incorporated into the ad-targeting system that is at the core of its business.

Cambridge Analytica and SCL were the subject of a number of previously unpublished harassment complaints filed in response to the numerous political survey and messaging calls made on behalf of US campaigns between 2013 and 2017.

Can a US technology company refuse to honor a court-ordered US search warrant seeking information that is stored at a facility outside the United States? Oral arguments in a pending case took place at the Supreme Court in February 2018, and they did not go well for Microsoft, the tech giant that is challenging a warrant for information stored at its facility in Ireland.

As a start-up called Cambridge Analytica sought to harvest the Facebook data of tens of millions of Americans in summer 2014, the company received help from at least one employee at Palantir Technologies, a top Silicon Valley contractor to American spy agencies and the Pentagon. It was a Palantir employee in London, working closely with the data scientists building Cambridge’s psychological profiling technology, who suggested the scientists create their own app — a mobile-phone-based personality quiz — to gain access to Facebook users’ friend networks. Cambridge ultimately took a similar ap

Amid public concerns over Cambridge Analytica’s use of Facebook data and a subsequent movement to encourage users to abandon Facebook, there is a renewed focus on how social media companies collect personal information and make it available to marketers.  While there is evidence that social media works in some important ways for people, Pew Research Center studies have shown that people are anxious about all the personal information that is collected and shared and the security of their data.

Facebook has been rocked by reports of a massive data scrape carried out by Cambridge Analytica and one of its then-contractors, a Cambridge University academic named Aleksandr Kogan. Kogan claims that the data he collected from thousands of Facebook users and their friends—amounting to data on over 50 million users—abided by Facebook’s terms; Cambridge Analytica promises it deleted the data; and Facebook is auditing everyone it can for signs of the data. But while Facebook provided the original data, it wasn’t the only vehicle for Kogan’s app.

[Commentary] The problems at Facebook and others, real and perceived, at Google, Amazon and Apple have led to an easy consensus: The large technology companies should be regulated. Such an outcome would be a bad mistake — bad for the companies, of course, but also bad for us, their users, and bad for the country. I do not pretend to be unbiased in writing this. While I am about as tech-savvy as your average 72-year-old , I met Mark Zuckerberg when he was 20, and spent six years on Facebook’s board.

A coalition of 37 state attorneys general are urging Facebook to provide more answers on how Cambridge Analytica improperly obtained the data of 50 million Facebook users. “These revelations raise many serious questions concerning Facebook’s policies and practices, and the processes in place to ensure they are followed,” the bipartisan group of attorneys general wrote.  “We need to know that users can trust Facebook. With the information we have now, our trust has been broken.”

The Federal Trade Commission confirmed that it has an opened a "non-public" investigation into Facebook Inc.'s privacy practices. The social media giant's stock quickly dropped more than 5 percent. It's now down more than 20 percent from its Feb. 1 high.

Recently, a New Zealand man was looking through the data Facebook had collected from him in an archive he had pulled down from the social networking site. While scanning the information Facebook had stored about his contacts, Dylan McKay discovered something distressing: Facebook also had about two years' worth of phone call metadata from his Android phone, including names, phone numbers, and the length of each call made or received. Facebook uses phone-contact data as part of its friend recommendation algorithm.
