A Statistical Investigation of Fingerprint Patterns
The spatial distribution of the features in fingerprints that are used for identification is studied. Conclusions are drawn on the significance of an observed occurrence of a feature in a particular location of the print.
Some improvements are presented in ways of analysing fingerprint images and representing the fingerprint pattern.
Although the uniqueness of fingerprints has been assumed for many years, it lacks a sound scientific basis. This has implications in law, since fingerprint based identification is used to obtain criminal convictions. This research is working towards the goal of being able to state, given two prints or partial prints that are alleged to originate from the same finger, what the likelihood is that such a match could have occurred by chance.
