Fingerprint Secure IoT Door Lock

Easily realize the secure IoT application with the TrustZone® for Armv8-M technology in NuMicro® M2351 series.

Protect the IPs in  "Secure World": The first developer, such as the algorithm provider, could store the fingerprint identification algorithm in "Secure World" with the enhanced protections of "eXecute-Only-Memory (XOM)" and "Two-level Flash Lock".
Collaborative secure software development in "Customization World": The secondary developer, such as the door lock vendor, could develop within the "Customization World (Non-secure World)". The secondary developer could only call the identification algorithm stored in "Secure World" without knowing the details of the algorithm. It's easy for both sides to develop secure applications.
