Abstract
Examples relate to identifying signatures for data sets. In one example, a computing device may: for each of a plurality of first data sets, obtain a data set signature; generate a first data structure for storing each data set signature that is distinct from each other data set signature; for each of a plurality of second data sets, obtain at least one data subset; generate a second data structure for storing each data subset; remove, from the first data structure, each data set signature that matches a data subset included in the second data structure; and for each data set signature removed from the first data structure, identify each first data set from which the data set signature was obtained; and for each identified first data set, obtain a new data set signature.
