Facial recognition: convenient or insecure?

There are a lot of “pros and cons” for Facebook users to tag their friends in a photo, computer vision professor Stefanos Zafeiriou from Imperial College London tells the Breaker.

It makes the social network more interactive, and also helps to spot and eliminate fake accounts which steal others’ identities. However, it could be invading users’ privacy as well.

Facebook users in Europe would be asked if they want their faces being spotted when they appear in friends’ uploaded photos.

A senior lecturer at Bournemouth University warns that the social media giant Facebook could be invading users’ privacy.

Here’s what Christopher Richardson says about how the social media giant could watch people when they are not aware of.

Professor Zafeiriou says that despite the convenience it has brought, facial recognition technology is not “very secure”. He explains: “The combination of face and other biometric information such as fingerprint is more secure.”

Every face has approximately eighty distinguishable landmarks, the different peaks and valleys that make up facial features.  Since 1960s, technology has been looking to measure these points on human face, creating a faceprint that helps recognise the person’s identity.

It’s used to capture perpetrator, eliminate voter fraud, and becoming popular in use by banks and airports.

However, the latest privacy scandal has raised concern where 50 million users’ personal data is used by the consultancy company Cambridge Analytica.
