This page lists devices that are currently unsupported by libfprint, which we'd like to support in future.

[edit] Introduction

This page tracks devices that are not supported by libfprint but would be nice to support in future.

The usual process is for someone who has one of the devices to perform USB sniffing and for us then to figure out how we can get one of the devices into the hands of a developer who can write a driver. We have project funds available to buy devices (and are not accepting further donations at this time). This is not a fast process, so please be patient.

[edit] Daniel's reverse engineering queue

  1. Apricorn Aegis Bio (integrated UPEK device) [in progress]
  2. USBest FPRD 1307:0172 in unreleased product [awaiting windows software]
  3. Validity VFS101 in a Silex S1 [working on purchasing this]
  4. UPEK TCRD4C in 2nd gen Eikon [not yet purchased]

[edit] DigitalPersona U.are.U 4500

DigitalPersona have released a new device. Nobody has reported sniff logs yet, but there does seem to be availability on ebay.

[edit] UPEK TCRD4C (newer Eikon)

The latest revision of UPEK's Eikon offering is a 147e:2016 device (as opposed to a 0483:2015 upekts device). Devices with this ID are usually supported by upeksonly but this is reported not to work.

Next step if someone wants to contribute: run this device under windows while sniffing the USB traffic, and publish sniff logs. Alternatively, probably easier, run it under Linux with UPEK's BSAPI and capture the transfer using usbmon.

I plan to buy one of these to get it working with fprint.

[edit] Validity VFS101

A new competitor on the market, Validity have recently got their sensors included in some popular laptops such as the HP Pavilion dv7. The USB for the VFS101 is 138a:0001. Under Windows, this hardware is driven by DigitalPersona software, leading some people to incorrectly assume that this is a DigitalPersona scanner.

I can't find much information about this device. Is there encryption? Is imaging done in hardware or software? (presumably software, presumably one of the main reasons to partner with DigitalPersona is to use their image processing code)

I have emailed Validity asking about the possibility of device specifications and/or sample devices. I will also follow up the same way with HP and HP's suppliers. However, these requests usually go nowhere.

Next steps that the community can do:

  • Try and get one of these devices into the hands of a capable developer
    • First we need to either source a laptop (unlikely) or a standalone device (do these exist?)
    • I will buy a Silex S1 from Amazon to work on, but I have other devices in the queue first. -dsd 19:37, 21 November 2008 (UTC)
    • Or can someone rip theirs out of their laptop? also unlikely...
  • Sniff logs so that some initial protocol analysis can be done
  • Start writing code (using libusb) that mimics the sniff logs

[edit] AuthenTec AES2550 & AES2810

There are new scanners in AuthenTec's range, which according to the specifications do fingerprint matching in hardware. We also have reason to suspect the protocol is encrypted, although the question is then: can we disable or break the encryption?

We need help in the following areas:

[edit] UPEK devices in Sony laptops

UPEK confirms that even though Sony laptops include a 0483:2016 scanner (which would otherwise be supported by upekts), the Sony version has a custom firmware designed to prevent any non-Sony software interacting with the device. Unfortunately they are successful and fprint, ThinkFinger and UPEK's own Linux drivers do not work with the fingerprint scanners in Sony laptops.

[edit] ZKSoftware ZK-6000

Leonardo Baeta Lopes reports that ZK-6000 doesn't work with libfprint, i.e. is not the same as the DigitalPersona devices which do work. It does look similar though, so I wonder if it is the next generation of the product. I think ZK is the OEM, and DigitalPersona just rebrand their products.

[edit] Sunplus 895

There are a surge of cheap fingerprint readers on ebay, and by tracing a few product names that can be seen on images, I think they are all based on the Sunplus 895 chip. Gerald Klaver has some information. In addition to funds and time to reverse engineer this, it appears that some extra work might be needed. It appears that this device sits behind a usb-serial converter, which we first need to write a kernel driver for, and secondly, fprint would need a bit of rearchitecting as it presently makes the assumption that all devices should be accessed using libusb.

[edit] Samsung ID Mouse

This was probably one of the first consumer fingerprint scanning devices and is hard to get hold of nowadays. There is a driver present in the Linux kernel for this device. It also presents an interesting challenge, as it does not offer any finger detection whatsoever: it is up to the software to determine when a finger has been placed on the sensor, through image analysis alone.

[edit] Authentec AES3400

Gerald Klaver has some information. Need one of these devices to work on. These are available standalone in the APC biopod devices. David Z's udrv driver looks like a good model (GK says its an AES4000 driver, but I don't see anything that suggests that is the case...)

[edit] Authentec AES3500

This is found in the Samsung X30 laptop. Tobias Wolf is working on a driver (see the mailing list). This is being tracked in bug:10

[edit] Magictec FIN002

The FIN002 appears to be manufactured by magictec.com.tw. Support for this device is being tracked on bug:11.

[edit] Futronic FS80/FS82

Biomark.org.ru has a driver for this, mostly closed source. This video shows some nice image quality and that their software can do enrollment/verification (but those parts are closed). If their open source part does not contain all the info we need to get images from such devices, it should be quite easy to reverse engineer the device through bus traffic analysis while running their software.

The FS82 is the FS80 with a smart card reader.

[edit] Misc devices

Here are some other devices on the consumer market. These should be researched before converting into their own sections above (e.g. which chipset/scanner are they based on?).
