A program for a plurality of instructions for providing diffusion information based on a query, an apparatus for providing diffusion information based on a query, a method for providing diffusion information based on a query, and a machine readable Non-transitory recording medium

摘要

In one example, the data security system may determine the degree of penetration of a file based on query data for an object (eg, a file or a hash of a file). Certain exemplary algorithms may be provided using statistically likelihood estimates of penetration, with little storage of data records, and hence may be used to determine the degree of penetration in O (1) time complexity (ie constant time) It can provide information. Such algorithms can be applied in near real-time, for example, to provide quick response to queries against the penetration of certain files.
