The widespread use of facial recognition technology is almost upon us. A new iPhone is on the horizon, and it might not even have a fingerprint reader—instead, you could be unlocking your phone with your face.
Facial recognition is not new. It’s been a sci-fi staple for decades, and its practical roots are in the 1960s with Palo Alto researchers on RAND Tablets manually mapping out people’s features. Even back then we could give a computer enough data to be able to match a person to a their photograph. The group, led by Woodrow William Bledsoe even managed to calculate a compensation for any tilt, lean, rotation and scale of the head in a photograph.

Data inputs stayed pretty rudimentary, with manual input of details being replaced by the Eigenfaces in the ‘80s and ‘90s. This would be the start of computer vision systems leveraging the kinda freaky power of big data.
