No one knows your face as well as your iPhone does. All the unique variances of your face that make it yours and yours alone, these are all data points that your iPhone uses to unlock your phone using a face in place of a thumbprint. This same data that the iPhone collects can be used by the underlying tech—facial recognition technology—in a vast array of applications, from border control to photo tagging to law enforcement. But is this data (the measurement of the space between the eyes, the texture of the skin, etc.) open data? Or do individuals have a right to protection of an image of their face?
