Conceived and developed a solution which enabled customizable device behavior based on biometric authentication during unlocking. This innovative approach allowed users to set distinct behaviors for different biometric profiles, enhancing the security and personalization of the device, and providing a more fine-tuned unlocking experience as compared to the conventional binary locked/unlocked system. The project was later adapted for use in the Samsung Knox offering.
