Network-Based Fingerprint Access Android Application Using Socket Communication

Purpose

Fingerprint access usually means the scanner and the device that unlocks are physically wired together, which is awkward the moment you want the reader in one place and control in another. A thesis team set out to cut that cord — letting a fingerprint reader authenticate a phone across a wireless network with no physical link between them.

Description

We built a fingerprint scanner that captures and matches prints, then sends the result across Wi-Fi to a mobile app that listens for scanner events in real time and drives the access decision. We built and tested each link on its own — the scanner, and the wireless channel in both connection modes — so the full chain could be trusted end to end. It's a networked hardware-and-mobile authentication system, the kind of tricky cross-device integration we're comfortable owning.
