Christchurch Call
What is being developed?
Software infrastructure is being built which will integrate a new set of privacy enhancing technologies (PETs). This will enable data scientists to remotely study data and algorithms distributed across multiple secure sites. Technologies including remote execution, federated learning, differential privacy, and secure multi-party computation will enable this remote research in a way that conforms to the data-use policies of the platform under study. 
The current project plan envisages work taking place approximately over a 9-month timeframe with a total cost of approximately US$1.5m.  

In brief these milestones are to: 
Build the underlying software and systems for the new infrastructure.
Do a proof of concept test using synthetic data to show that the system works.
Trusted partner(s) test out the system on real datasets, showing reproducibility and proof of function.

What is each partner contributing?
New Zealand is providing a financial contribution and assistance with establishing the initiative. New Zealand will also provide coordination between the Call Community and the project to ensure transparency, visibility, and that opportunities are maximised for Call supporters and partners to make use of the project’s output. 
The support of New Zealand and the USA will help to ensure the project outcomes are developed on behalf of the wider
