Abstract
A data-leakage prevention capability is presented herein. The data-leakage prevention capability prevents leakage of data, of a file set having a plurality of files, from a secure network using online fingerprint checking of data flows at a boundary of the secure network. The online fingerprint checking is performed using a set of data structures configured for the file set. The data structures for the file set are configured based on file set characteristics information of the file set and a target detection lag indicative of a maximum number of bits within which a data leakage event for the file set is to be determined. The data structure configuration is computed for a plurality of data structures configured for use in monitoring the files of the file set. The data structure configuration includes a plurality of data structure locations and data structure sizes for the respective plurality of data structures.
