Biometric Technologies (432 KB, PDF)
Key points:
- Biometric attributes are generally universal and permanent. They can be measured and analysed to produce a digital signature that is sufficiently distinctive to an individual to enable their identification.
- Biometric technologies can be used to check that someone is who they say they are (for example, checking that someone’s face matches the photo in their passport), or to identify an unknown person based on a previous obtained record (for example, comparing a fingerprint from a crime scene to a fingerprint database of previous offenders).
- Use of biometric technologies is increasing, driven by: the perceived vulnerability and inconvenience of passwords and other conventional proofs of identity; increasing use of mobile devices with biometric capabilities; and the growing power of biometric systems, which have benefited from advances in computing technologies such as artificial intelligence.
- There is currently debate over whether current regulation of biometrics is adequate, especially for police use of facial recognition technology, which has increased in recent years.
- The use of biometric technologies raise various challenges, including concerns around privacy, public acceptance, and the potential for bias.
- The Home Office has just published a delayed strategy for Biometrics.
