![]() ![]() Recognising the importance of the evolving use of biometrics and the concerns raised, the Ada Lovelace Institute (Ada) has undertaken a three-year programme of public engagement, legal analysis and policy research, to explore the complex ethical challenges raised by biometric technologies and consider what governance is necessary to ensure biometrics are being used with public legitimacy. Solving the technical problems does not make these technologies safe: the use of biometrics can lead to bias and discrimination that stem not from the technology itself but from the way it is used in context, for example to over-police marginalised communities, or to use stereotypes to make unfounded judgements about people in situations like hiring or education. This differential inaccuracy is itself a clear form of bias, which may be addressed as the technology improves. ![]() Similarly, if people’s traits, characteristics or abilities can be automatically assessed on the basis of biometrics, often without a scientific basis, this may affect free expression and development of personality.Įntangled with these potential harms are issues of bias and discrimination, which arise from the fact that some biometric technologies – and facial recognition technology, in particular – function less accurately for people with darker skin. If people’s identities can be detected by both public and private actors at any time, that may significantly infringe on someone’s privacy as they move through the world, which may result in a chilling of free expression, free association and free assembly. And employers have used facial expression and tone analysis to decide who should be selected for a job.Īlongside a proliferation of biometric technologies, a number of issues have been raised about their impact on people and society, in particular regarding their impact on human rights. Companies have proposed using facial expression analysis to detect whether students are paying attention in online class. Shops can use similar technology to monitor customers. Police can deploy live facial recognition technology to monitor football matches and protests. We unlock smartphones with our faces or fingerprints, and can pass through border security by presenting our passports and faces to a camera that automatically matches the two. These types of biometric data are now being collected and used in a wide range of situations for many distinct purposes. It is inherently linked to who we are and cannot be easily changed, hidden or separated from our personal identity. It captures our faces, fingerprints, walking style (gait), tone of voice, expressions and all other data derived from measures of the human body. ![]()
