- Abstract summary: We present PriMIA, a software framework designed for privacy-preserving machine learning (PPML) in medical imaging.
We show significantly better classification performance of a securely aggregated federated learning model compared to human experts on unseen datasets.
We empirically evaluate the framework's security against a gradient-based model inversion attack.

- Abstract: The utilisation of artificial intelligence in medicine and healthcare has led
to successful clinical applications in several domains. The conflict between
data usage and privacy protection requirements in such systems must be resolved
for optimal results as well as ethical and legal compliance. This calls for
innovative solutions such as privacy-preserving machine learning (PPML). We
present PriMIA (Privacy-preserving Medical Image Analysis), a software
framework designed for PPML in medical imaging. In a real-life case study we
demonstrate significantly better classification performance of a securely
aggregated federated learning model compared to human experts on unseen
datasets. Furthermore, we show an inference-as-a-service scenario for
end-to-end encrypted diagnosis, where neither the data nor the model are
revealed. Lastly, we empirically evaluate the framework's security against a
gradient-based model inversion attack and demonstrate that no usable
information can be recovered from the model.

Machine learning (ML) and Artificial Intelligence (AI) have fueled remarkable advancements, particularly in healthcare. Within medical imaging, ML models hold the promise of improving disease diagnoses, treatment planning, and post-treatment monitoring.
Privacy concerns surrounding patient data hinder the assembly of large training datasets needed for developing and training accurate, robust, and generalizable models.
Federated Learning (FL) emerges as a compelling solution, enabling organizations to collaborate on ML model training by sharing model training information (gradients) rather than data (e.g., medical images)

and Matrix Decomposition [0.0]
Deep learning (DL) solutions have been extensively researched in the medical domain in recent years.
The usage of health-related data is strictly regulated, processing medical records outside the hospital environment demands robust data protection measures.
In this paper, we use singular value decomposition (SVD) and principal component analysis (PCA) to obfuscate the medical images before employing them in the DL analysis.
The capability of DL algorithms to extract relevant information from secured data is assessed on a task of angiographic view classification based on obfuscated frames.

Collaborative machine learning techniques such as federated learning (FL) enable the training of models on effectively larger datasets without data transfer.
Recent initiatives have demonstrated that segmentation models trained with FL can achieve performance similar to locally trained models.
However, FL is not a fully privacy-preserving technique and privacy-centred attacks can disclose confidential patient data.
