Table 1
Figure 12 is that the present invention solves mobile phone remote transmission/reception fingerprint characteristic data, a kind of preferable aerial connected mode that is adopted, i.e. GPRS agreement.This is because the fingerprint characteristic data amount that is transmitted is all bigger, can not adopt the note SMS mechanism of existing mobile phone to transmit.So adopt high transfer rate, set up seamless, direct-connected GPRS mode with the Internet net with 171.2kbps.
GSM mobile handset is that the air interface between mobile station MS and the service GPRS strong point SGSN is Um among Figure 12.The existing explanations of earlier figures 5 that are of five storeys of the communication protocol of Um Interface.Because network layer provides TCP/IP and agreement X.25, various traditional GSM network hardware resources such as base station sub-system BSS and network service subsystem NSS etc. are because of having disposed these protocol softwares, when transfer of data and become transparent.The present invention needn't relate to the following transmission of network layer details, only needs the fingerprint characteristic data that need transmit directly is packaged into TCP or UDP message bag, utilizes the GPRS agreement to transmit and gets final product.The data format of TCP or UDP bag, visible correlation technique data.
Figure 12 is the feature extraction that takes the fingerprint, template recording program block diagram.Detailed process is to obtain fingerprint image 12.1; Feature 12.2 takes the fingerprint; If extract successfully 12.3, deposit in the feature list feature in 12.4, obtain fingerprint image 12.1 otherwise return; Expire 12.5 if feature list has been arranged, all features are merged generation fingerprint template 12.6, obtain fingerprint image 12.1 otherwise return; If template successfully produces 12.7, this template is preserved 12.8, EP (end of program) is obtained fingerprint image 12.1 otherwise return.
Figure 13 is a fingerprint comparison flow chart.At first obtain fingerprint image 13.1; The feature 13.2 that takes the fingerprint, if extracts successfully 13.3, the template 13.4 that then takes the fingerprint compares 13.5 with template and characteristic value, exports comparison result 13.6; Obtain fingerprint image 13.1 otherwise return.The structure of backstage fingerprint base: cell-phone number is a major key, and fingerprint template is a field.Server is determined the finger print identifying scope according to cell-phone number, carries out one to one finger print identifying.Background server system, fingerprint base system can be with existing " wired " systems, but need set up wireless transmission platform, are note or multimedia message at present.Middle wireless platform is known technology at present, is wireless as present social security and medicare system, but can adds the wireless authentication platform fully, makes things convenient for the user.
