The social network previously announced alterations to its members' settings without asking for fresh consent. The website is changing its policy after an investigation by the US Federal Trade Commission, according to a report by the Wall Street Journal. Facebook is not commenting on the story at this time. The report suggests the site has also agreed to privacy audits by an independent organisation over the next 20 years. Privacy campaigners have welcomed a report that Facebook is to ask users to opt into any changes in the way it uses their personal information.
