The Massachusetts Institute of Technology's (MIT) David Shrier recently detailed the MIT Trust::Data Consortium's efforts to build new systems that rethink data sharing and security.

Shrier said privacy and encryption are important, but a need exists to securely access private data for multiple use cases. "We need a policy around us owning our own personal data and not Facebook and we should also have an audit trail of access," he said. "And we want to be able to share information when we want."

He proposed sharing answers to a query instead of full datasets, and his data collection model would have a query function that communicates with different pieces of code to ensure only authorized queries are accessing the system.

Shrier noted the general trust model can employ blockchain to provide a cryptographically verified distributed system for audits, with computation and query executed in a sandbox to further bolster data security.
