It could be a useful tool for identifying people, or the end of anonymity as we know it: a British company has created technology that can identify who a person is by scanning their face.
Blippar, the augmented-reality start-up, has added the feature to its app, allowing anyone to point their phone's camera at a person and see if the image matches a face on its database. The company said it was the most-requested addition to the app, which is used to scan and identify real-world objects such as food and buildings.
The feature has launched with a list of 70,000 public figures such as politicians, musicians and sports personalities. Members of the public will soon be able to add their own face to the app by scanning it from different angles.
