Fingerprint Scanner Zf1

[Patricia]

IntegratedBiometrics offers the most reliable, lightest weight FBI-certified fingerprint sensors in the world. Based on patented LES technology, our continuing innovation has resulted in sensor products that were unimaginable just a few years ago.

After switching from a broken Manjaro to Ubuntu 22.04 and struggling with clearing the fingerprint memory, I was able to clear and reset fingerprints using the fprint guide from Arch wiki. Specifically,

Interesting (to me) note: I just re-installed Manjaro alongside Ubuntu 22.04 (which has fingerprint authentication enabled). I was able to enroll my fingerprint in Manjaro without having to run the above first, which surprised me.

@nrp Could you share the instructions for installing the Goodix driver(s) mentioned in your other blog post? Running Ubuntu 21.04 and looking to start using the fingerprint reader before the commits make it to the core OS.

A lot of distros tend to run on older versions in order to ensure everything works properly. It should be safe to update to a newer version anyways, but having a guide specifically for the Framework laptop would be even better.

If someone wants to see Ubuntu to support the fingerprint feature for Framework laptop on a future released version, you need to ask a Debian libfprint package maintainer to upgrade to the latest libfprint version. Because Debian is the upstream distro of Ubuntu. Maybe you can find a way to open the ticket somewhere in the Debian libfprint package tracker page. And same for other distros too!

Great news! I got an answer from the Fedora libfprint maintainer that the libfprint >= 1.90.7-3.fc34 on normal Fedora 34 should work for Framework laptop. Because they applied a patch file (update-goodix.patch) to fix the issue in the RPM spec (recipe) file libfprint.spec rather than upgrading to the upstream version.

Looking at the libfprint repository (for 1.9.2 release v1.92.0 libfprint / libfprint GitLab) and the meson webpage (tutorial at Quickstart Guide) I get how it ought to compile, but if there are any gurus out there who know what to do with the compiled products - eg does the meson build automatically put the needed files in the right places or does something have to be moved into place? - would be grateful for guidance. Thanks!

Has anyone gotten the fingerprint sensor working in arch yet? I have libfprint installed at the latest compatible version but gnome 40 still does not recognize the fingerprint. I would love to get this figured out and added to the arch linux thread.

sudo apt install gtk-doc-tools libfprint-2-dev libgirepository1.0-dev libgusb-dev libpam-wrapper libpam0g-dev libpamtest0-dev libpolkit-gobject-1-dev libxml2-utils python3-pip python3-pypamtest

sudo pip install meson

People have patterns of friction ridges on their fingers, these patterns are called the fingerprints. Fingerprints are uniquely detailed, durable over an individual's lifetime, and difficult to alter.[5] Due to the unique combinations, fingerprints have become an ideal means of identification.[6]

There are four types of fingerprint scanners:[7] optical scanners, capacitance scanners, ultrasonic scanners, and thermal scanners. The basic function of every type of scanner is to obtain an image of a person's fingerprint and find a match for it in its database. The measure of the fingerprint image quality is in dots per inch (DPI).[8]

All fingerprint scanners are susceptible to be fooled by a technique that involves photographing fingerprints, processing the photographs using special software, and printing fingerprint replicas using a 3D printer.[9]

From early 2000, some laptops with PC Card support can be equipped with readers; for example, Compaq Armada E500 can be optionally equipped by external fingerprint reader since 2000 - the reader module was released by Toshiba.[12] IBM produced laptops with integrated readers since 2004.[13] Apple's marketing name of electronic fingerprint recognition, known as Touch ID, was introduced in 2013 only for smartphones, and laptop option was released only in 2016. The implementation was delayed until 2013 just because the integrated with optical trackpad scanner were be patented by RIM (Blackberry) in 2004.[14] On laptops and smartphones, the fingerprint sensor is usually use USB or I2C interface.

My fingerprint scanner also stopped working. No issues with the passcodes. Custer support was no help because its beyond the warranty date. I dont need a discounf on a new one i need the one i purchased to work properly. If so many people are having the same issue it must be some sort of defect. Has anyone been able to fix theirs?

If your fingerprint sensor light was off when pressing your finger on it, please check the wire and carefully reconnect the connector between the Interior Assembly and the Exterior Assembly. Guide to Disconnect/Reconnect the Keypad Wire

Since about a month ago the fingerprint scanner for my laptop is not working anymore, in the sense that when I switch on the notebook, the sensor's light doesn't even blink...Not sure if this is related to any software update, I don't remember exactly, but there was a Window update that I allowed in December and I'm thinking it may be related to that...

Based on some of the recommendations I found here, I went to Device Manager - Biometric Devices, and clicked on the only option I have there - 'Validity Sensors (WBF) (PID=0050)', only to see the following error message: 'Windows has stopped this device because it has reported problems. (Code 43)'. Does anyone know what that means and/or what can be done?

Create a backup of all your most critical / sensitive files to other than on the computer. For example, copy the files to your Cloud backup. to a USB stick, "Somewhere" you can access the files should the computer become unavailable.

You may already have a Windows PIN login set up and ready to go. Should there be a problem with the PIN, in most cases, you will receive a notice from Windows that there is an issue - you can then reset the PIN as needed.

I'm making a web application and would like to have a secure area where you can only sign in with your finger print. My original idea was to just use a usb barcode reader and you scan that, and it outputs the ID into a text box, but that's not very secure. So I want to use a USB fingerprint reader to maybe generate a hash for each person and store that in a text box instead. Which then will check that against a database with everyone's hash value. Does anyone know if there is a fingerprint reader out there that can do this, or of a way I can easily integrate a reader into a website?

EDIT: The Idea for this website is that it's like a login system (Sort of like how you can clock in and out if you get paid hourly) The idea is that no one can sign someone else in and out. IF you just use a password, than someone can just tell their friend the password who can type it in. That's why I thought of a fingerprint, or something similar... I'm open to other suggestions

EDIT 2: The Basic idea, is I have to come up with a way to Prove someone was there by checking in. I don't want to use passwords, because then someone can just tell someone else their password to type in. Any other suggestions? It doesn't have to be fingerprints.

Biometrics are not secret. Every time you touch something, you're leaving your password laying around. Every time your picture gets taken your facial image / retinal image gets copied. Passwords have to remain secret to be useful.

Fingerprints never exactly match. Even if you scan your own right index finger twice in a row, the scans won't be the same. So "hashing the fingerprint" won't work - two hashes of the same finger would be indistinguishable from two hashes of two different fingers (with a good, cryptographically strong hash).

Fingerprint readers work by storing some key onboard, and letting that key out if and only if the fingerprint given is close enough to what they expect. The fingerprint itself is not used to get direct access to anything outside the reader.

EDIT: updating this answer. There is, now in the year 2014, a standard from the FIDO Alliance called "UAF" which allows sites to use fingerprint authentication in a way that works across different sites. Rumor has it Paypal is going to begin using it soon.

Biometry for remote authentication is never secure. You can't know if a real finger with that fingerprint is in a reader, or if the user only sends you an image. So a fingerprint just becomes a password the user can never change, which is the same for every service you login to, and which is left on every object the user touches.

Biometry can only work for local authentication where you trust the reader to be not hacked(i.e. you have physical control over the reader) and the reader can distinguish a real finger/eye/... from a fake one. Which most can't.

It is possible to create a one way hash of a finger print. You first have to extract a number of observables just like you might do for a fuzzy match. But since you need an exact match for a hash you need to throw error codes at the values you extracted which then can correct the minor differences on each measurement. It's not easy to code and it doesn't fix the fundamental problems listed above, but it should be possible.

So you want to use a local authentication mechanism to authenticate a remote resource? There are many issues here to suggest this would not be a smart choice. E.g., how does the web app know the hash belongs to the original user and not someone who has a duplicate?

What I would suggest instead is to go the route of banks from several years ago when they had smartcard readers sent to credit card customers. Use the fingerprint scanner to store a local copy of the user's login name, requiring a second form of authentication such as a password.
