Linux Mint 16 w/ Targus PA460 (AES4000)

I am trying to get a Targus PA460 capacitive fingerprint scanner 
(Authentec aes4000 driver) working with fprint and have had mixed (but 
generally unacceptable) results.  I am running Linux Mint 16.

I tried first with the stock Linux Mint binary packages and although the 
scanner is always recognized, I was unable to enroll a finger; after the 
first scan, fprintd would stop responding; other users have reported the 
same problem.  I have 4 scanners and they all behave identically.  When 
running fprintd -t in a console so I can see the results, the daemon 
shows no activity when the fprintd-enroll task requests a rescan.

I rebuilt from source using libfprint-0.5.1 and fprintd-0.5.1 and the 
results were better.  I was able to get fingerprints enrolled using 
fingerprint-gui, but it is very flaky and crashes frequently crashes.  
With fprintd-enroll I was also able to enroll my right index finger 
only.  fprint-verify sometimes verifies successfully, but it generally 
fails.  There is also a serious defect in that if a scan fails, it will 
not retry and the client app (enroll or verify) must be killed to resume 
scanning (see defect reports below).

I realize the PA460 is a poor scanner (250dpi, 10mm square, 96x96 
pixels), but one problem may be contrast; fprint_demo shows the captured 
images and they have extremely light contrast; I have seen images 
captured by fprint_demo with other scanners and they show high contrast 
between ridges and grooves.  I tried increasing the sensor gain 
(libfprint/drivers/aes4000.c:94) from 0x23 to 0x33 and the results 
seemed to improve.  I found the hardware manual and non-official linux 
USB driver source here: 
http://sourceforge.net/projects/aes4kusbdriver/   I'll read it and 
experiment some more, to see if I can get better results.

That's likely related to Lubuntu's PAM configuration. I would take that
up with the distribution. In Fedora, the PAM configuration will try to
use the fingerprint first (for login at the console), and GNOME (gdm,
lock screen) password prompts will allow for either to be used.

fprintd-enroll was built as a test/debug application, so it's obviously
not as polished as UIs that were built around fprintd, such as GNOME's
User Accounts panel. That's worth a bug report though, and we'll look
into making fprintd-enroll better.

Lubuntu 14.04, Thinkpad x61s

Hi,

Couple of questions and suggestions from a new user.
Is it the normal behavior of fprint to show no feedback when fingerprint is un/successfully scanned (at login, xscreensaver etc)?
Should the user have to press enter for the fingerprint to "take" after it's scanned? It's somewhat counter-intuitive since one expects the authentication to be either fingerprint OR keyboard entry, not mix of the two - it feels like pressing enter to the empty password box.
Fprintd-enroll should maybe show some info or feedback when fingerprints are entered. It could tell user that it expects multiple scans. I scanned, waited, waited, then ctrl+C'd myself out and nothing worked of course. Since the message after first scan is something like "Success" users might think that's that, and quit or just wait for the program to quit.

Thanks,
G.

Quite simply I'm having issues with the contrast and brightness with 
this driver:

An example of a scan motion that would work well with it's windows 
driver is here:

cannot make imaging example work

Hi,

I cannot make the img_capture.c example work.
I'm using an UPEK EikonTouch 300 on linux with latest libfprint 0.5.1, while other enroll/verify examples do work.

The UPEK EikonTouch 300 is claimed to support imaging:
http://www.freedesktop.org/wiki/Software/fprint/libfprint/upektc/

it fails with the following ouput:
Found device claimed by UPEK TouchChip/Eikon Touch 300 driver
Opened device. It's now time to scan your finger.

image capture failed, code -95


Where can I find documentation about this error code ?
Grepping headers returns nothing, I only found this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=60445

Any hints ?

Regards,
xan.

Experiences with libfprint in multi user environments

Hi,

I am currently working on a unit where I need fingerprint identification
of up to 50 users. The system is going to run on Linux (right now with a
Raspberry Pi as host) which is why I use libfprint. Installing/compiling
newest libfprint (from the git repo) has been done.

I have good experience with the UPEK touchstrip sensors, however in
multiuser environments I have the feeling that, first of all the number
of false negatives are a bit high, probably mostly due to how small the
sensor is, thus increasing the risk for people to make an "erroneous"
swipe. I feel that for an application to use fingerprint, for people to
not get "pissed" at the system, it must be rather stable.

Therefore I am calling for some experience regarding the different
readers supported by libfprint regarding to stability and ease of use
(for the user), before I just start randomly buying readers :)
My best guesses right now are the URU4500 and EikonTouch 300 (are the
500/510's supported?) since they use "touch" type which I guess would be
easier for the user, and give more minutiae easier, but this is more a
guess, since I only have experience with the touchstrip versions.

Any help is appreciated!

Kind regards,
Martin Hejnfelt

Fprintd V_0_5_1 compiling and installation from sources, ask for doublecheck

For install new Fprintd V_0_5_1 to replace old from current Debian repository I need:

Download sources from:


Then I need to unpack it somewhere.

Then I need to probably follow:
./configure; make; make install

But I cannot to find how and where to run 
./configure

Because of 'no file or command'.

Could someone please help me?

Thank you very much

How do you think, why this old revision are included in Raspbian repositories?
Should it be reported in some place / to someone?

Hi Mariusz,

"** (fprintd-verify:3531): CRITICAL **: dbus_set_g_error: assertion
`gerror == NULL || *gerror == NULL' failed" means fprintd (not
libfprint) version is too old (several years or so)

Regards
Vasily

How to compile fprintd-enroll and fprintd-verify from source code?

Hello.

I would like to compile fprintd-enroll and fprintd-verify from repositories:

I would like to use them instead of out of date and not working properly packages fprintd-enroll and fprintd-verify from Raspbian (Raspberry Pi) repositories.

What / how should I proceed to replace old fprintd-enroll and fprintd-verify  packets and then use newest (compiled from sources) ?

Thank you very much for any help

Best regards
Mariusz Ciszewski
