Fingerprint matching algorithm is studied in this paper.A fast point pattern matching algorithm based on core and delta information obtained from fingerprint classification is achieved.It successfully and rapidly solve the problem of image rotation

translation and transformation in fingerprint matching.Core points of inquery image and model image are used as a pair of reference points

and the parameter of rotation and translation are computed.The inquery image is rotated and translated against the model image

then these two images are matched based on point pattern.
