If you are looking for your wife at the airport and she is the first person to come through the door and walk up to you... do you stop the process there or continue to look for her? | ||

AFIS takes the image of the fingerprint and creates a search code using limited information from the print. This search code is then run through the database and the algorhythm produces a respondent list according to how closely the search codes match. NB AFIS does not compare the images, it compares the search codes. The operator is then presented with the images from the respondent list. It is up to the operator to use their training and experience take each respondent in turn and determine whether it matches. The process does not stop there. That declaration of an identification then has to be verified by another examiner. NB the identification is decalred and verified by examiners using the same methodology as they would use if they were working with a loft and an inked set of prints. Once you have found a match there is no point continuing down the list because, knowing that fingerpints are unique, you know that none of the others can possibly match. If you're looking for a specific legal precedent in a legal dictionary and the first case you look at is the one you wanted, do you search through the rest of the library? | ||

i am a law student working a motion to exclude digital enhanced fingerprints. Does anyone know the standard procedure for requesting respondents from the AFIS? How exactly is a match made? Also, it is standard protocol if the first comparison is a "match" to stop the process there? |
