  • 05-2aHave you prepared measures to defend against poisoning and evasion attacks?
    • In the healthcare sector, there is a possibility of a misdiagnosis due to a data attack, such as an external attacker accessing and altering medical image data [17]. Examples of hospital medical data vulnerabilities include the following:
    ✓ Radiation medical device network exposed to the internet
    ✓ Vulnerable security track records owned in the medical (healthcare) industry
    ✓Lack of internet network security (e.g. outdated software/operating system, lack of or insufficient encryption, exposed infrastructure)

    • Therefore, malicious adversarial attacks by attackers may occur not only against AI training data collected through hospitals, but also against training data collected and established internally. Therefore, it is necessary to prepare countermeasures.

    • There are various defense techniques to enhance the robustness of AI services and defend against adversarial attacks. Some of the best techniques to block poisoning and evasion attacks in the data design and model training stage include adversarial training, gradient masking, and feature squeezing, which can also be applied in the healthcare sector.
