Digital signature generation apparatus, comprising an envelope generator operable to generate an envelope representation, of only one polarity, of a sampled data segment, and operable for each of successive portions comprising a predetermined plurality of samples to provide a portion sum value as the sum the values of the samples in the portion, thereby to provide said envelope representation; a threshold value generator operable to determine a threshold value for each portion of the envelope representation; an event detector operable to detect, as an event, a transition of a portion sum value across the threshold value for the portion concerned; and a signature generator operable in response a detected event to generate a digital signature characteristic of the sampled data segment.

La présente invention concerne un appareil de production de signatures numériques, comprenant un générateur d'enveloppe apte à produire une représentation d'enveloppe, d'une seule polarité, d'un segment de données échantillonné, et apte à fournir, pour chacune des parties successives comprenant une pluralité prédéterminée d'échantillons, une valeur de somme de partie correspondant à la somme des valeurs des échantillons de la partie, afin de fournir ladite représentation d'enveloppe ; un générateur de valeur de seuil apte à déterminer une valeur de seuil pour chaque partie de la représentation d'enveloppe ; un détecteur d'événement apte à détecter, en tant qu'événement, un passage de la valeur de somme de partie par la valeur de seuil pour la partie concernée ; et un générateur de signature apte à produire, suite à la détection d'un événement, une signature numérique caractéristique du segment de données échantillonné.
