Fusing Spectral Signatures and Activation Clustering for Backdoor Detection in Healthcare Imaging Models: Method, Implementation, and Evaluation

Machine learning models are increasingly deployed in healthcare imaging pipelines for diagnostic support, and training-time attacks against them are a named sector-level concern: healthcare-sector guidance identifies model poisoning and adversarial attacks as threats requiring de...

Toward Automated Detection of Data Poisoning and Backdoor Attacks in Healthcare Imaging AI: A Proposed Detection Methodology and Evaluation Framework

Machine learning models are increasingly deployed in healthcare imaging pipelines for diagnosticsupport, yet the security of these models against training-time attacks — particularlydata poisoning and backdoor insertion — remains substantially under-tested relative to theirgrowin...
