US Patent 10496840 Recommending security controls for similar data

Security controls applied to a set of data, such as a data volume, can be recommended based on comparing the contents of the data set against those of other data sets and locating other data sets with the same or similar data. Security controls applied to those other data sets, but not applied to the set of interest, can be recommended for application to the data set. In order to protect customer data, the data to be compared can be sampled from the data set and analyzed for aspects such as present patterns, structures, or data types. In some embodiments various derivations can be generated, as may include hashes, checksums, or summaries based on the underlying data, and these derivations can be compared for purposes of finding data sets including similar data. Security controls can be recommended for tasks such as data placement, storage, or migration.
