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 includes identifying a set of files from among a plurality of file pairs. Each file pair is formed from a respective file that includes at least one difference with respect to each snapshot. The method includes performing 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 includes performing 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 includes annotating data in remaining files in the set of files as potentially being the sensitive data, subsequent to the reducing processes.
