1. Upon completion of four or more successful fingerprint acquisitions the enroll score shows an actual value as in the example below This value changes based on the clarity of the image the number of minutia available for extraction and the weight each minutia has been given according to prior matches Though it is possible to keep the finger on the sensor throughout the seven acquisitions to increase template quality the finger should be lifted and replaced between each acquisition Enroll Score 4 41 enrollment SUCCESFULL switch to verification Completing seven acquisitions is more likely to produce a higher score because with each additional acquisition specific minutia can gain a higher weighting Enroll Score 7 77 enrollment SUCCESFULL switch to verification To stop the enrollment process do not touch the sensor until a timeout has occurred The LCD will display the final enroll score and will ask for the switch to be moved to verification If the final score is less than 25 then enrollment is insufficient and the process will be restarted as in the example below Enroll Score 5 22 enrollment failed Score lt 25 NOTE The demonstration will only store one fingerprint template at a time 6 MCF5249 Fingerprint Security Reference Design User s Guide MOTOROLA For More Information On This Product Go to www freescale com Freescale Semiconductor Inc 3 2 Verification Mode In verificat2.

7. latent fingerprint images residual fingerprints left on the surface of the sensor Since these images can be used to fool the system if the sensor takes an image when no finger is present the algorithm detects based on adjustable rotational and translation thresholds images that are too close or identical to the last matched fingerprint If the captured fingerprint image is detected as identical to the previous matched image the LCD will display a message that indicates this condition The algorithm s ability to detect latent fingerprint images can be demonstrated during verification by leaving the finger on the sensor There is also a web server running on the MCF5249 as part of the application that displays the images taken from the sensor There is one page that shows the seven images taken as part of the enrollment mode and another page that shows the last image taken by the sensor To demonstrate the web server connect a crossed Ethernet cable directly to the PC and switch the proxy server off in Internet Explorer Tools Internet Options Connections LAN settings before opening the webpage http 10 0 0 10 via the address bar To return to booting with dBUG after using the Flash version switch jumper 12 back to pins 1 2 MOTOROLA MCF5249 Fingerprint Security Reference Design User s Guide 7 For More Information On This Product Go to www freescale com Freescale Semiconductor Inc 5 Revision History Table 1 provides revisi
