Privacy enhancing technologies in model development

Dear Community!

I am a PhD researcher at the London School of Economics and am exploring the field of privacy enhancing technology (PET) usage in ML model development (e.g., approaches like differential privacy) and their societal and organisational implications. However, I am struggling with finding data sources that allow me to analyse the diffusion of PETs (in the best case across companies or locations). One thought was that model cards on Huggingface would capture the usage of PETs - is that the case? do you have other data sources in mind I that indicate PET usage?

Thanks so much for your support!
