Facebook has rolled out its facial recognition technology to countries outside of the US, but has switched the feature on by default without telling its users first.
UK-based security expert Graham Cluely noted  earlier today that Facebook had slotted the tech into the social network.
The Mark Zuckerberg-run company started using its facial recognition software in December last year for its Stateside users in a move to automatically provide tags for the photos uploaded by Facebook users.
The tech works by scanning newly uploaded pics and then identifies faces from previously tagged photos already stored in Zuckerberg’s internet silo.
When the software was introduced in the US late last year, Facebook pointed out that users could disable the function.
