Attacks on Heartbeat-Based Security Using Remote Photoplethysmography.

Robert Mark Seepers, Wenjin Wang, Gerard de Haan

    IEEE Journal of Biomedical and Health Informatics
    |April 10, 2017
    PubMed
    Summary

    Remote photoplethysmography (rPPG) accurately mimics contact photoplethysmography (PPG) signals, posing a security threat to mobile-health solutions. However, electrical cardiac signals remain secure against these remote attacks.

    Area of Science:

    • Cybersecurity
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Interpulse interval (IPI) from cardiac signals offers unique identifiers for mobile-health security.
    • Trusted devices typically require physical contact for secure authentication.
    • Remote sensing techniques like remote photoplethysmography (rPPG) challenge existing security assumptions.

    Purpose of the Study:

    • To evaluate the threat posed by state-of-the-art rPPG methods to heartbeat-based security systems.
    • To assess the feasibility of remote attacks bypassing physical contact requirements for authentication.

    Main Methods:

    • Utilized state-of-the-art remote photoplethysmography (rPPG) techniques.
    • Compared the accuracy of rPPG with contact photoplethysmography (PPG) for identifier generation.

    Related Experiment Videos

  • Assessed rPPG's ability to replicate identifiers from electrical cardiac signals.

    • Main Results:

    • rPPG demonstrated accuracy comparable to contact PPG.
    • rPPG poses a significant threat to security systems relying on contact PPG identifiers.
    • rPPG failed to accurately capture identifiers from electrical cardiac signals.

    Conclusions:

    • Heartbeat-based security systems using contact PPG are vulnerable to rPPG-based remote attacks.
    • Electrical cardiac signal-based authentication remains secure against current rPPG technology.
    • Future security solutions should consider the implications of remote sensing technologies.
