Privacy concerns over Russia's 'most popular search engine' Yandex as its uses facial recognition

A Russian search engine is being accused of providing an unregulated facial recognition system to members of the public -- violating personal privacy. Experts have slammed the feature as'poor' and'creepy' while dubbing it a'definite privacy concern'. Yandex, much like Google, Bing and other search engines, allows users to input an image and see similar results. But only Yandex, which claims to conduct more than 50 per cent of Russian searches on Android, produces images of the exact same person. MailOnline tested the image search facilities of Yandex, Bing, Google and specialist site TinEye by submitting a photo that was not available online.
