JOHANNESBURG - Facebook yesterday said that data firm Cambridge Analytica had unauthorized access to up to 87 million users' data, much higher than the 50 million users previously reported.

Mike Schroepfer, the chief technology officer at Facebook, said according to the information at its disposal, just over 70 million of the affected was in the US, more than a million in the Philippines, more than a million in Indonesia and more than a million in the UK.

Schoepfer said the company had introduced nine changes it is making to protect your Facebook information.

“Overall, we believe these changes will better protect people’s information while still enabling developers to create useful experiences. We know we have more work to do — and we’ll keep you updated as we make more changes,” Schroepfer said.

Details of the steps Facebook has introduced:

- Events API: apps using the API will no longer be able to access the guest list or posts on the event wall

- Groups API: all third-party apps using the Groups API will need approval from Facebook and an admin to ensure they benefit the group.

- Pages API: all future access to the Pages API will need to be approved by Facebook.

- Facebook Login: Facebook will need to approve all apps that request access to information such as check-ins, likes, photos, posts, videos, events and groups

- Instagram Platform API: Facebook has announced deprecation of the Instagram Platform API effective yesterday.

- Search and Account Recovery: Previously people could enter another person’s phone number or email address into Facebook search to help find them, Facebook has now disabled this feature.

- Call and Text History: Facebook has reviewed this feature to confirm that Facebook does not collect the content of messages — and will delete all logs older than one year.

- Data Providers and Partner Categories: Facebook has shut down Partner Categories, a product that lets third-party data providers offer their targeting directly on Facebook.

- App Controls: Starting on Monday, April 9, we’ll show people a link at the top of their News Feed so they can see what apps they use. and the information they have shared with those apps. People will also be able to remove apps that they no longer want.
