METHOD TO GENERATE PRINT FOR SOUND SIGNAL Russian patent published in 2011 - IPC G06K9/00 G10L19/00 

FIELD: information technologies.

SUBSTANCE: invention relates to a method for generation of a print for a useful signal, besides, the useful signal is a time layout of spectrum that contains useful signal frequencies, for instance, sound frequencies, which makes it possible to automatically detect identical or similar useful signals in an efficient manner, besides, the print is resistant to modifications of a useful signal, which are not visible to a user - a person. Besides, at least one set of data, containing a part of a useful signal, is processed with an analyser in compliance with the predetermined analysing instruction, besides, the analyser generates a data vector of a print as a result of processing, which depends on a processed data set and identifies it. The invention also relates to a method of useful signals identification in a predetermined set of useful signals, a device for generation of a useful signal print, a device for identification of useful signals in a predetermined set of useful signals, in a system for identification of useful signals in a predetermined set of useful signals.

EFFECT: increased efficiency of print generation process.
