I don't quite understand their example - they reproduce a study done with de-identified genomic data. For each patient, the data required for the analysis are the number of mutations in the tumour, the type of tumour and how long they lived for. The genomic data cannot be related back to an individual. I guess it is just a toy example rather than an actual use case.
It seems that their model would work best when sharing rich data like medical records or perhaps imaging. But it isn't clear to me that the more sophisticated analyses required for such datasets can be done with their system.
It also occurs to me that analyses done with these privacy preserving methods will not be reproducible, since the data is just not available. They don't mention reproducibility once. On the other hand, you can download the data used in the study of tumor mutational burden and run the analysis yourself [1].
Perhaps they aren't big on reproducibility. They don't make their code available actually...

The fact that they don't share any data is down to these particular researchers, not a consequence of their methods as the entire baseline for the field of medicine is that sharing raw data is a gross ethical violation.

I work on a variety of health data problems that would benefit from a practical FHE implementation with standards backing. This Federated Analysis (FA) piece is new to me, but mainly because I deal with it from the infrastructure side and not the research side. Google has a good blog post on it: https://ai.googleblog.com/2020/05/federated-analytics-collaborative-data.html https://ai.googleblog.com/2020/05/federated-analytics-collab...
