Abstract: This disclosure relates to a system for managing access to compliant collaboration data. A collaboration data store stores collaboration data that is encrypted with a collaboration master key associated with a collaboration between one or more organisations. The collaboration master key is shared by the one or more organisations associated with the collaboration. A key store stores the collaboration master key associated with the collaboration. A governance module determines the collaboration data is compliant with a set of compliance rules and based on the determination selectively cause access to be granted to the collaboration master key. Access by the same entity is prevented to two or more of the collaboration data store, key store and governance module.
