Facebook announced a series of changes on Wednesday to give users more control over their data, after a huge data scandal which has wiped more than $100 billion from its stock market value.

The company has faced a global outcry after a whistleblower revealed, on March 17, that data from 50 million users was improperly harvested to target US and British voters in close-run elections.

Strengthening policies

“The last week showed how much more work we need to do to enforce our policies, and to help people understand how Facebook works and the choices they have over their data,” Erin Egan, Vice President and Chief Privacy Officer, and Ashlie Beringer, Vice President and Deputy General Counsel at Facebook, wrote in a blog post. “So in addition to Mark’s announcements last week cracking down on abuse of the Facebook platform, strengthening our policies and making it easier for people to revoke apps’ ability to use your data we’re taking additional steps in the coming weeks to put people in more control over their privacy.”

The measures come ahead of a landmark European Union data protection law in May. The social network will add a new ‘Privacy Shortcuts’ menu which will let users worldwide review what they’ve shared and delete it, as well as features enabling them to download their data and move it to another service.

Facebook shares have fallen almost 18 per cent since March 17. Users’ data was improperly accessed by British political consultancy Cambridge Analytica, which was hired by Donald Trump’s 2016 presidential campaign. The company’s CEO, Mark Zuckerberg, has repeatedly apologised and bought full-page advertisements in US and British newspapers promising to do more to restrict access to users’ information.

More control

While Facebook said on Wednesday the changes it was announcing had been in the works for some time, it said the events of the “past several days underscore their importance”.

The Privacy Shortcuts menu will allow users to control their data in a few taps, including by letting them add more protection to their account, like two-factor authentication. “You can review what you’ve shared and delete it if you want to. This includes posts you’ve shared or reacted to, friend requests you’ve sent, and things you’ve searched for on Facebook,” Egan and Beringer wrote.

Users will also be able to manage the information Facebook utilises to serve them ads and download the data they have shared with Facebook—including photos, contacts and posts—and move it to another service.

The EU General Data Protection Regulation enters into force on May 25 and requires companies to give people a “right to portability”, namely to take their data with them. It also introduces hefty fines for companies breaking the law, running up to 4 per cent of global revenues.

Lawmakers in the United States and Europe are demanding to know more about Facebook's privacy practices and Zuckerberg is due to testify before the US Congress.
