Abstract: This invention refers to a fingerprint verification method and apparatus based on global ridgeline. Firstly, the invention search base point pair between the stored fingerprint template and the fingerprint template to be matched. The said base point pair is the positioning reference for position calibration between the stored fingerprint template and the fingerprint template to be matched. Secondly, generates fingerprint template after minutiae extraction with additional use of thinned global fingerprint ridgeline information. Then, observe similarity of minutiae topological structure or surrounding ridgeline distribution to determine base point pairs. Finally, align two fingerprints through base point pair alignment. Calculate matching ratio of ridgelines to determine whether two fingerprints match. Beneficial results of present invention: By using global ridgeline information, efficiency of searching & interference resistance capacity is greatly enhanced.

Abstract: An identity credence and a method for producing the same are provided in the present invention. In order to produce the identity credence, the issuing organ firstly constructs a first information packet which comprises identity information and biometrics information; then selects an asymmetric encryption algorithm for digital ciphering on the first information packet with a private key to generate a second information packet; and finally stores the second information packet generated by ciphering into a medium to produce an identity credence.

Abstract: A fingerprint hard disk has been provided in the present invention. Said fingerprint hard disk comprises a fingerprint identifier for identifying whether the user's fingerprint is qualified, wherein said fingerprint identifier includes a control interface for issuing a control signal according to the identification result of the fingerprint identifier; and comprises a hard disk including a hard disk body and a hard disk control device which is used to receive a control signal issued by the control interface of the fingerprint identifier to control the operating state of the hard disk body. The fingerprint identifier and the hard disk are combined organically; and the fingerprint of a specific user may be recorded in advance as required, and then, by identifying the fingerprint, only said specific user will be allowed to open the hard disk and read the data.
