  • Method and device for generating fingerprints of information signals
    Patent number: 10248723
    Abstract: Method and system for generating a fingerprint representing a portion of an information signal. The method comprises decomposing a portion of the information signal into plural frequency sub bands at a decomposition level, calculating a spectral property of the signal in each of said plural frequency sub bands, comparing each spectral property against a first criterion thereby generating a comparison result, combining each comparison result for constituting the fingerprint, at least once repeating the decomposing, calculating, comparing and combining, wherein for each repetition the decomposing is performed using a decomposition level different from a previous decomposition level.
