Key result
ECG-based heart biometrics offer strong spoofing tolerance and liveness detection for user authentication.
Why the study?
Heart biometrics offer advantages such as liveness detection, but while ECG-based authentication has shown success, exploration of other cardiac signals remains limited.
This survey highlights the potential of heart biometrics, particularly ECG, for secure user authentication with liveness detection, while identifying challenges for future development.

May enhance secure cardiac device access; leaves open prospective validation and standardization.
In recent years, biometrics (e.g., fingerprint or face recognition) has replaced traditional passwords and PINs as a widely used method for user authentication, particularly in personal or mobile devices. Differing from state-of-the-art biometrics, heart biometrics offer the advantages of liveness detection, which provides strong tolerance to spoofing attacks. To date, several authentication methods primarily focusing on electrocardiogram (ECG) have demonstrated remarkable success; however, the degree of exploration with other cardiac signals is still limited. To this end, we discuss the challenges in various cardiac domains and propose future prospectives for developing effective heart biometrics systems in real-world applications.

Rathore et al. (2020) conducted a review in User authentication. Heart biometrics vs. Traditional passwords, PINs, and state-of-the-art biometrics was evaluated. Heart biometrics, primarily utilizing electrocardiogram signals, offer advantages in liveness detection and strong tolerance to spoofing attacks for user authentication.
