Abstract

A method is provided for preventing divulgation of sensitive data in two snapshots, taken at different times, of one or more same systems in a cloud environment. The method identifies a set of files from among file pairs. Each file pair is formed from a respective file that includes at least one difference with respect to each snapshot. The method performs a pattern reducing process that removes, from the set of files, any of the files having, as the difference, a predetermined non-sensitive difference between respective executions of a pre-determined system operation. The method performs a commonality reducing process that removes, from the set of files, any files having, as the difference, a common difference between different users. The method annotates data in remaining files in the set as potentially being the sensitive data, subsequent to the reducing processes. The two snapshots include at least one Sandbox-based image.
