Summary
Background Cloud computing promises to essentially improve healthcare delivery performance.
However, shifting sensitive medical records to third-party cloud providers could create
an adoption hurdle because of security and privacy concerns.
ObjectivesThis study examines the effect of confidentiality assurance in a cloud-computing environment
on individuals’ willingness to accept the infrastructure for inter-organizational
sharing of medical data.
MethodsWe empirically investigate our research question by a survey with over 260 full responses.
For the setting with a high confidentiality assurance, we base on a recent multi-cloud
architecture which provides very high confidentiality assurance through a secret-sharing
mechanism: Health information is cryptographically encoded and distributed in a way
that no single and no small group of cloud providers is able to decode it.
ResultsOur results indicate the importance of confidentiality assurance in individuals’ acceptance
of health clouds for sensitive medical data. Specifically, this finding holds for
a variety of practically relevant circumstances, i.e., in the absence and despite
the presence of conventional offline alternatives and along with pseudonymization.
On the other hand, we do not find support for the effect of confidentiality assurance
in individuals’ acceptance of health clouds for non-sensitive medical data. These
results could support the process of privacy engineering for health-cloud solutions.
