Nearly a quarter of Facebook users are not doing enough to protect their personal data on the social network.
A Consumer Reports study has revealed that 23 per cent of users either don't know what privacy measures the site offers, or have failed to enable them.
Forty-two per cent of respondents put their complete date of birth in their profile, while nearly 26 per cent uploaded pictures of their family and friends with their full names and other details.
Seven per cent people post their complete address on their profile page and a further three per cent even update their status message to indicate when they're not at home.
Facebook has been severely criticised for its privacy policies by government agencies around the world, including a group of US senators, who have advised the company to better protect the privacy of its users or face the wrath of the US government.
