London, Oct 25 (AP) Britain's Information Commissioner has slapped Facebook with a fine of 500,000 pounds (USD 644,000) the maximum possible for its behavior in the Cambridge Analytica scandal.

The ICO's investigation found that between 2007 to 2014, Facebook processed the personal information of users unfairly by giving app developers access to their information without informed consent.

The fine was the maximum allowed under the law at the time the breach occurred.

Had the scandal taken place after new EU data protection rules went into effect, the amount would have been far higher.

Social media companies have come under pressure globally following allegations that political consultancy firm Cambridge Analytica used data from tens of millions of Facebook accounts to profile voters and help US President Donald Trump's 2016 election campaign. (AP) RUP RUP 10251428 NNNN.
