More and more key players in the tech industry are voicing their concerns over the use of personal data following Facebook's massive Cambridge Analytica scandal. Executives from Apple Inc and IBM Corp have called for more oversight on how personal data is used following the consultancy firm's improper use of data, which affected more than 50 million Facebook users. Speaking at the three-day China Development Forum in Beijing, Apple chief Tim Cook said'well-crafted' regulation was required, while IBM Corp chief Virginia Rometty said users should have more agency over their own data. Executives from Apple Inc and IBM Corp have called for more oversight on how personal data is used following the Facebook Inc breach that saw roughly 50 million users' data misused by consultancy Cambridge Analytica. Facebook has come under intense scrutiny from users, lawmakers and investors following allegations from a whistleblower that it allowed British political consultancy Cambridge Analytica to improperly use data and build voter profiles that were later used to help elect U.S. President Donald Trump in 2016. U.S. lawmakers on Friday officially requested that Facebook's Mark Zuckerberg explain at a congressional hearing how user's data was released to the consultancy.

Last week, reports surfaced that the FTC was opening an investigation into Facebook regarding Cambridge Analytica's use of its data. The agency has now confirmed that it is indeed investigating the social media giant. "The FTC takes very seriously recent press reports raising substantial concerns about the privacy practices of Facebook," the FTC said in a statement. "Today, the FTC is confirming that it has an open non-public investigation into these practices." Just over a week ago, a number of reports detailed how Cambridge Analytica obtained Facebook profile information on over 50 million Facebook users through a researcher that collected the data with an app.

Political pressure on Facebook continued to intensify as a key Senator invited CEO Mark Zuckerberg to testify before Congress and a regulatory agency confirmed it had launched an investigation. The scrutiny stems from revelations that a political consultancy employed by Donald Trump's presidential campaign harvested some 50 million Facebook users' worth of data via a survey app. As Facebook executives have scrambled to reassure users their personal information remains protected, elected officials have demanded Mr Zuckerberg himself appear before Congress. That push gained momentum with the embrace of Senator Chuck Grassley, an Iowa Republican who chairs the powerful Senate Judiciary Committee. Paralleling the augmented attention from Congress, the Federal Trade Commission confirmed it had opened an investigation into Facebook's privacy and data security practices.

The Federal Trade Commission's Bureau of Consumer Protection confirmed Monday that has undertaken a non-public investigation into Facebook's data practices, according to a statement from Tom Pahl, the agency's acting director. The announcement comes just over a week after The New York Times and the The Guardian published explosive reports about the reported improper use of data belonging to 50 million Facebook users by the Trump-campaign affiliated data firm Cambridge Analytica. This isn't the first time the FTC has investigated the social network's data practices. In 2011, Facebook agreed to settle charges--though admitted no actual fault--that it "deceived consumers by telling them they could keep their information on Facebook private, and then repeatedly allowing it to be shared and made public," among other overreaches. The settlement barred Facebook from making further deceptive privacy claims, required it obtain a user's explicit approval before changing the way it handles their data, and mandated that Facebook receive periodic assessments of its privacy practices by third-party auditors for the next 20 years.

British data firm Cambridge Analytica allegedly sent foreigners to the U.S. to provide campaign advice to Republicans. Nathan Rousseau Smith has the story. In the aftermath of Facebook's data miscues, two more tech giants agree there's a need for better regulations to protect personal data shared online. Speaking at the three-day China Development Forum in Beijing, Apple CEO Tim Cook and IBM CEO Ginni Rometty both called for additional protections for user data. "I'm personally not a big fan of regulation because sometimes regulation can have unexpected consequences to it, however I think this certain situation is so dire, and has become so large, that probably some well-crafted regulation is necessary," said Cook, according to a report on the event from Reuters.
