Editor's Notes
- #10: All the things you are The number of proposed biometric technologies increases daily. Starting with the well-established fingerprint systems to the more esoteric such as ear geometry (commonly left by listeners at crime scenes in Switzerland, apparently), gait (the way you walk) and body odour. How should you go about deciding the most appropriate technology for any given application? Biometric technologies are useful means of identifying people against databases or verifying that they are who they say they are. A small number of technologies are good at the former function (e.g. iris and fingerprint) whereas many are capable of verification against a biometric template stored on a token such as a smart card or travel document. There are many different applications for these two functions within UK government such as: Verifying that a document holder is the legitimate document holder by matching them against a biometric held within the document. Preventing duplicate applications for documents by searching against the database of currently issued documents. Preventing people holding different identities on different systems (e.g. Driving License vs Passport) by sharing and cross-checking biometric data. Ensuring that only legitimate members of staff have access to secure areas and systems. The complexity of the individual requirements of each application coupled with the speed of advance of biometric technologies means that there is no single best biometric for all applications.
