This project aims on reverse engineering protocol of Validity 138a:0090, 138a:0094, 138a:0097 fingerprint readers, creating specification and FLOSS libfprint driver.
Main chat of this project:
libfrprint issue: https://bugs.freedesktop.org/show_bug.cgi?id=94536 Lenovo forums: https://forums.lenovo.com/t5/Linux-Discussion/Validity-Fingerprint-Reader-Linux/td-p/3352145
- spec.md - Specification draft, the main work goes here right now.
- dissector.lua - Wireshark dissector for decrypting communication after key exchange.
- libfprint directory - libfprint repo with this driver integrated
- prototype - Standalone prototype(extremly ugly code, would be completly rewritten for driver)
Prototype testers are needed, please share your result and join us in our Gitter.
| Device | Status |
|---|---|
| 138a:0090 | Fingeprint capture works in prototype |
| 138a:0091 | Seems like different protocol, doesn't work |
| 138a:0094 | Doesn't work yet, but looks promising |
| 138a:0097 | All crypto and capture operations work in prototype, no image because it stores them internaly |
