资源说明：Ray's version of vfs101driver
Some tools to examine Validity VFS101 sensors.
Quickstart
-----------------------------------------------------------------------
To produce an image of your fingerprint under Linux:
$ mkdir -p img/X img/Y
$ make
$ ./src/proto woot personal
... wait for "00 16 00 00 00 FF FF 01" scrolling by...
... swipe your finger ...
This _should_ produce a fingerprint in img/X/out-000-00.pnm
Monitoring the device under Windows
-----------------------------------------------------------------------
To use this, you need:
- Machine with a VFS101 fingerprint reader
- Windows
- UsbSnoop
Boot up under windows, install UsbSnoop, and monitor the biometric
device. Go to Services, stop the DigitalPersona and Validity services,
then restart them. Swipe a few fingerprints, then save the UsbSnoop
log as UsbSnoop.log.
Analysing the USB dump
-----------------------------------------------------------------------
To use this, you need:
- Linux
- UsbSnoop.log file from previous step
Boot up under Linux, copy UsbSnoop.log into this folder, and do this:
$ cat UsbSnoop.log | ./scripts/UsbSnoop.pl > UsbSnoop.txt
$ mkdir img2
$ cat UsbSnoop.txt | ./scripts/Snoop2Api.pl > src/mine.h
$ gwenview img2
This should produce:
- a set of API calls in src/mine.h
- PNM images of your fingerprints under img2
Testing the device under Linux
-----------------------------------------------------------------------
To use this, you need:
- Machine with a VFS101 fingerprint reader
- Linux
To import the results of your Windows USB capture, do this:
$ vi src/proto.c
... hook up mine.h, see commit a2fa7c94ee26d233a259fd84538338c7f6b114b1
... you will need to rename PREFIX_ to something else
$ make
Once you've imported your Windows log, or if you just want to use a
pre-existing cycle, do this:
$ mkdir -p img/X
$ ./src/proto woot personal > output
This should produce:
- a logfile of Linux vs Windows USB transactions in output
- PNM images of your fingerprints under img
Personal Information
-----------------------------------------------------------------------
Personal information is defined as images of your fingerprints, or enough
data to produce such images.
The UsbSnoop.log and UsbSnoop.txt files contain enough information to
reconstruct images of your fingerprints.
The Snoop2Api.pl script will extract this information and produce PNM images
under img2/
By default, ./src/proto will not produce any personal information. IF you
explicitly select a cycle routine (eg: 'woot') AND provide a second argument
"personal", then ./src/proto may (depending on the cycle you select...)
- monitor the fingerprint scanner
- print on stdout enough information to reconstruct your fingerprints
- produce PNM images of your fingerprints under img/
