Secure multi-party data analysis: end user validation and practical experiments
Dan Bogdanov and Liina Kamm and Sven Laur and Pille Pruulmann-Vengerfeldt
Abstract: Research papers on new secure multi-party computation protocols
rarely confirm the need for the developed protocol with its end users.
One challenge in the way of such validation is that it is hard to explain
the benefits of secure multi-party computation to non-experts.
We present a method that we used to explain the application
models of secure multi-party computation to a diverse group of end users
in several professional areas. In these interviews, we learned that
the potential users were curious about the possibility of using
secure multi-party computation to share and statistically analyse
private data. However, they also had concerns on how the new
technology will change the data analysis processes.
Inspired by this, we implemented a secure multi-party
computation prototype that calculates statistical functions in the same way as
popular data analysis packages like R, SAS, SPSS and Stata.
Finally, we validated the practical feasibility of this application by conducting
an experimental study that combined tax records with education records.
