Traditional passwords are inadequate as cryptographic keys, as they are easy to forge and are vulnerable to guessing. Human biometrics have been proposed as a promising alternative due to their intrinsic nature. Electrocardiogram (ECG) is an emerging biometric that is extremely difficult to forge and circumvent, but has not yet been heavily investigated for cryptographic key generation. ECG has challenges...
Photoplethysmography (PPG) signals have unique identity properties for human recognition, and are becoming easier to capture by emerging IoT sensors. Existing research on PPG-based biometric systems rely on fiducial methods that extract landmarks from the PPG signal as features. This paper investigates non-fiducial methods that operating in a holistic manner that is less sensitive to noise in landmarks...
The Internet of Things (IoT) is a concept that involves connecting endpoint devices and physical objects to the Internet. While IoT is envisioned to dramatically increase convenience in our daily lives, it could also result in catastrophic economic and safety issues. Considering the applications envisioned for IoT (smart cities, homes, retail, etc.), security must be handled with great care and should...
