The Congressional Research Service recently issued a report that examines legal protections for information stored in the cloud. The report is authored by Richard M. Thompson II, a Legislative Attorney with CRS.
The Congressional Research Service (CRS) provides research and analysis at the request of members of Congress. The CRS does not make the reports they produce publicly available, but there are several websites that have begun collecting these reports and making them available. The University of Northern Texas has a database that collects and preserves CRS reports, which is searchable by keyword or by subject matter. OpenCRS is also a good resource for finding CRS reports.
