The rapid spread of connected objects in healthcare environments, i.e. Healthcare Internet of Things (HIoT), has motivated concerns on data privacy. Thus, security mechanisms are required to restrict access to such data. Biometrics, measurements, and calculations related to human characteristics can be collected from the target biosignal (e.g., electrocardiogram - ECG) and employed for authentication. This work investigates a continuous heart-based biometric authentication system for HIoT. We propose a system to provide authentication mechanisms mainly targeted at preserving users’ privacy and respecting low cost and scalability. This system employs fiducial features from Electrocardiogram (ECG) to produce a security token that corresponds to the user’s identification. We evaluate our system through simulation experiments performed using a Proof of Concept (PoC) implementation and ECG samples from an open database. In these experiments, it is possible to observe the feasibility of our proposal as well as its desirable properties.
