Dear MEL Topic Readers,

Biased and wrong? Facial recognition tech in the dock

What is face recognition, or FR? It is a method of identifying or verifying the identity of a person by the images of their faces. Face recognition systems use computer algorithms to pick out specific, distinctive details about a person’s face, such as distance between the eyes or shape of the chin. Then, they convert the information into mathematical data and compared with data of a face recognition database. Facial data can be collected from social media, Closed-circuit Television (CCTV), traffic cameras, published or private photos, or organizations’ database without being recognized by the person. So, if the face of a known terrorist is captured by security cameras in a public place like an airport or station, face recognition system alerts the authority for attention or action. It surely saves time and could save lives.

However, how reliable face recognition technology is? Unfortunately, it varies by situation and object. The angle and brightness of the image, and the skin color and gender of the object all affect the accuracy of the identification system. Also, there are technical difficulties that are unique to machines. For example, differentiating photos of a blueberry muffin and the face of a chihuahua dog isn’t an easy task for facial recognition.

Some authorities use FR aggressively to identify criminals, unwanted or suspicious people in public places. In fact, there are hundreds of millions of CCTV cameras installed in China. On the other hand, law enforcement agencies of San Francisco are banned to use facial recognition for fear of threatening civil liberties and making false alerts.

Is technology always flawless, or close to perfect? Which is more reliable, human eyes or AI-powered face recognition?

Enjoy reading the article and think if you feel more secure in an airport with face recognition security system.
