For more than 30 years my name has been associated with biometrics. It all started in 1990 when, at a conference I spotted a prototype of a hand geometry reader and very quickly became involved in a voice verification device. I then looked at retinal scanning, the early prototypes for iris recognition and, of course, a whole range of fingerprint readers. I undertook a great deal of research myself while also sitting on the UK Government Biometrics Working Group and was the deputy chairman of the Biometrics Association. I was the first person in the world to write a Windows based application for biometrics (using hand geometry), the inventor of the BANTAM application modelling language for biometrics and PKI, the inventor of the Proximity Matching Method, inventor of the Biometric Operability Index, inventor of the SilkPad encryption system and the only person in the world to come up with a solution to the problem of equivalence of realised performance across nodes. Not only did I find a solution, but I built an entire software suite which enabled centralised management of an unlimited number of nodes with automatic equivalence matching built in. I have also written six or seven books on the subject. Consequently, I thought it might be interesting to include just a few of the hundreds of papers that I have written over the years and make them freely available here. Bear in mind that some of them were written many years ago. I hope that you enjoy perusing them.
