The T-Model 9.2 Fingerprint Match Probability Calculator © estimates both the probability that a particular arrangement of fingerprint ridge features with occur in a part of a distal fingerprint in a person in the relevant population, and it estimates the conservative (upper bound) number of fingerprint close matches or "look-alikes" as well, thereby establishing a demarcation between sufficiency and insufficnecy to infer identification.

The latest version of the calculator includes estimates of numbers of look-alikes for fingerprint populations that range from one hundred to one trillion. This allows the trier of fact to see how inference for fingerprint identification depends on the relevant population for the case at hand.

T-Model 9.2 Fingerprint Calculator 

The T-Model Fingerprint Calculator © is currently available to the fingerprint community for purposes of independent research and validation study. For a copy of the latest version of the open source calculator in Microsoft Excel format, which has been updated with current discriminating values for fingerprint ridges features based on data gathered as a result of extended close match experiments, please contact Henry Templeman at the below email address or telephone number:
