Apple has bought Israeli startup RealFace, a cybersecurity and machine learning firm specializing in facial recognition technology. The company, formed in 2014, appears to have been purchased for $2 million, or several million dollars, according to the Times of Israel or Calcalist respectively. Several sites have floated the theory that the rumored iPhone 8 could have an embedded iris scanner that would let you unlock the phone by looking at it and another report speculates that the next iPhone will include tech like RealFace's as an alternative to the current Touch ID fingerprint scanner authentication system.
