METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR DETERMINING DATA SIGNATURES IN DYNAMICALLY DISTRIBUTED DEVICE NETWORK Russian patent published in 2014 - IPC G06F11/14 

FIELD: information technology.

SUBSTANCE: apparatus for determining data signatures in a dynamically distributed device network includes a processor which is configured receive a first query; generate a local partial closure of the data identified by the first query; synthesise a data signature of the local partial closure, the data signature being an irreducible polynomial expression and orthogonal to remote data signatures generated from remote partial closures; and store the data signature in a data bank within the dynamically distributed device network.

EFFECT: high efficiency of processing data.
