SINGAPORE – Unnaturally smooth skin, unsynchronised speech and questionable sources – these are some of the tell-tale signs Madam Lim Siew Gin, 70, has learnt to tell a deepfake apart from a real video.

“Some people have shared a deepfake video of Senior Minister Lee Hsien Loong promoting cryptocurrency with me on WhatsApp before,” said the retired uniformed officer, adding that she was not duped by this ruse as she keeps up with news reports on such scams.
