  • Data breach detection
    Patent number: 11562065
    Abstract: Systems and methods are described for a data breach detection based on snapshot analytics. The described systems and methods identify a plurality of snapshots of a data structure, identify a plurality of leaf nodes of the data structure for each of the snapshots, generate a vector of data attributes for each of the leaf nodes, assign a weight to each of the vectors to produce a set of weighted vectors for each of the snapshots, compute a distance metric between each pair of the snapshots based on the corresponding sets of weighted vectors, and detect an abnormal snapshot among the plurality of snapshots based on the distance metrics.
    Type: Grant
    Filed: August 22, 2019
    Date of Patent: January 24, 2023
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
