我自己的印象中，第一次對臉部識別技術有感是Facebook相簿會自動tag自己或朋友開始，後來google photo跟各大公司也開始應用。從阿里巴巴開設了自動人臉辨識並支付的智慧超市，再到iPhone X的Face ID刷臉解鎖(最近知道google photo連寵物也可以辨識了…)。
The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognise each other and is crucial to formation if complex societies. So is the face’s ability to send emotional signals.
People spend much of their waking lives reading faces. Technology is rapidly catching up with the human ability to read faces. For example, in China it verifies the identities of ride-hailing driver.Apple’s new iphone use it to unlock the homescreen.
The ability to record, store and analyse images of faces cheaply, quickly and a vast scale promises one day to bring about fundamental changes to notions of privacy, fairness and trust.
One big difference between faces and other biometric data, such as fingerprints, is that they work at a distance
photographs of half of America’s adult population are stored in databases that can be used by the FBI. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but a enormous potential cost to citizens’ privacy.
Some firms are analysing face to provide automated diagnoses of rare genetic conditions. Systems that measure emotion may give autistic people a grasp of social signals they find elusive.
When shown a pictures of one gay man and one straight man, the algorithm could attribute their sexuality correctly 81% of the time. In countries where homosexuality is a crime, software which promise to infer sexuality from face is an alarming prospect.
Less violent forms of discrimination could also become common. Facial recognition enabling firms to filter all job application for ethnicity and signs if intelligence and sexuality.
Such system may be biased against those who do not have white skin since algorithms trained on data set mostly white faces do not work well with different ethnicities.
Dissembling helps grease the wheels of daily life. The basis of social interactions might change from a set of commitments founded on trust to calculations of risk and reward derived from the information a computer attaches to someone’s face.
Relationship might become more rational, but also more transactional.
Legislation can help alter the balance of good and bad outcomes. European regulators have embedded a set of principles in forthcoming data protection regulationLaw against discrimination can be applied to employer screening candidates’ images.
However, such rules cannot alter the direction of travel.Cameras will only become more common with the spread of wearable devices. Amazon and Microsoft are both using their cloud services to offer face recognition; it is central to Facebook’s plans. Governments will not want to forgo its benefits. Change is coming. Face up to it.
