Facebook says it will toughen up its rules and safeguards around political adverts to prevent foreign interference in elections.
The social media giant is still reeling from last year's Cambridge Analytica scandal, which showed the British firm acted improperly acquired the data of millions of U.S. Facebook users to target election advertising.
Facebook's head of global affairs, former British Deputy Prime Minister, Nick Clegg, said the firm will require anyone running political adverts to be authorised and made to put a disclaimer showing who paid for the ad.
Facebook aims to launch the new tools in late March, to protect the integrity of the Euopean elections due this spring.
Last week in Davos Facebook COO Sheryl Sandberg said the company would improve its security.
(SOUNDBITE) (English) FACEBOOK COO, SHERYL SANDBERG, SAYING: "We're investing billions of dollars a year in what is a much more rigourous security effort, and we know we need to earn back trust and that means we need to prove it.
So, from everything from election integrity to fake news on our platform to getting the right content up to protecting people's data and information, we're taking a much more rigourous approach." Facebook said the transparency tools for electoral ads will be used globally before the end of June.
Clegg also said the ads will be stored in a publicly searchable library for up to seven years and contain info like the amount of money spent and who paid for the ads.
