Systems or methods gathers information within a network of computers regarding the distribution of documents to calculate the impact of a cyber security incident for a given computer. Specific embodiments analyze word usage within data files and to determine that data files are different versions of a document and use presence of documents on a given computer to determine the impact of a security breach at that computer.

Method and apparatus for predicting the impact of security incidents in computer systems

A video image frame consisting of a two-dimensional array of picture elements (pixels) is decomposed into a set of rectangular image portions (tiles). Within each tile, variance between pixel intensity values is less than a predetermined value. A tile is encoded by a value set identifying the tile and including a single intensity value for all pixels in the tile. Frame-to-frame variation of the video image is encoded by inter-frame tile comparison and encoding of sub-tiles representative of change from a previous frame to a current frame.
