Belfast tech startup using automated lip-reading to make user authentication systems more resistant to spoofing attacks — Liopa — “LipSecure works in conjunction with the vendor’s existing FR [facial recognition] system and prompts the user to repeat a random sequence of digits that appear on their screen. Liopa’s AI-based Visual Speech Recognition (VSR) technology checks if the digits have been spoken or mimed correctly and thus determines if there is a ‘live’ person present.”
