Generally, technicians adopt somewhat different approaches and methods from AFIS (Automatic Fingerprint Identification System) when they independently judge the similarity of two fingerprints based on the determination of fingerprint characteristics. In this paper, the analyses were developed at extracting and recognizing fingerprint features according to our experience, therefore revealing the difference on fingerprint query and processing between AFIS and artificial recognition. Thus, the strategy of man-machine coordination has been concluded against the incidence where AFIS made the fingerprint features labeled with deviation, left out and even erred.
