Will Abramson, Adam James Hall, Pavlos Papadopoulos, Nikolaos Pitropakis, William J Buchanan
2020 arXiv   pre-print
However, this engenders a lack of trust between data owners and data scientists. Data owners are justifiably reluctant to relinquish control of private information to third parties.  ...  However, architectures distributed amongst multiple agents introduce an entirely new set of security and trust complications. These include data poisoning and model theft.  ...  An organisation providing ML capabilities needs data to train, test and validate their algorithm. However, data owners tend to be wary of sharing data with third-party processors.  ...
