Cloud computing has not been adopted widely by industries that require a high level of security — such as health care and defense — because the technology cannot be held accountable and does not comply with data-protection regulations. Hasan is working to change that by finding ways to leverage provenance — the history of data, applications and cloud state — as a first-class property of clouds. The cloud architecture, he says, provides mechanisms for collecting, storing and creating a secure access mechanism for provenance and he'll use his $485,897 NSF Career Award to advance this work.
