Facebook has agreed to reduce the amount of time it retains information deleted by the user, such as tags and friend requests.
It will have to get more consent for the use of facial recognition and there will now be more transparency and control over how personal information is used for advertising on the site.
In a statement this afternoon, Facebook said the audit “highlighted several opportunities to strengthen our existing practices”.
It said it was committed to either implement, or to consider, other improvements recommended by the Commissioner.
Facebook has agreed to make these changes between now and July of next year.
