Claims (10)
1. Fremgangsmåde til verifikation af identiteten af en talende baseret på den talendes stemme, omfattende trinene a) at modtage en stemmeytring af et password eller en pass-sætning; b) at anvende biometriske stemmedata til at verificere (10), at den talendes stemme svarer til den talende, hvis identitet skal verificeres baseret på den modtagne stemmeytring; c) at afvise den talende, hvis den talendes stemme ikke verificeres; og kun hvis den talendes stemme verificeres: d) at verificere (12, 13), at den modtagne stemmeytring ikke er forfalsket, omfattende at bestemme, om stemmeytringen kan være forfalsket og at acceptere den talende, hvis det bestemmes, at stemmeytringen ikke er forfalsket, og at kræve en anden stemmeytring kun hvis det bestemmes, at stemmeytringen kan være forfalsket, at verificere, at den anden stemmeytring svarer til den talende, hvis identitet skal verificeres, og at afvise den talende, hvis det ikke verificeres, at den anden stemmeytring svarer til den talende, hvis identitet skal verificeres, og kun hvis det verificeres, at den anden stemmeytring svarer til den talende, hvis identitet skal verificeres, efter at have verificeret den talendes identitet at bestemme, om der er en eksakt overensstemmelse mellem de to stemmeytringer; og kun hvis det ikke bestemmes, at der er en eksakt overensstemmelse mellem de to stemmeytringer: e) at acceptere (16) den talendes identitet, der skal verificeres, i tilfælde af, at det bestemmes, at der ikke er en eksakt overensstemmelse mellem de to stemmeytringer, og ikke ellers at acceptere (15) den talendes identitet, der skal verificeres.
2. Fremgangsmåde ifølge krav 1, hvor bestemmelsen af, om stemmeytringen kan være forfalsket, omfatter en, tre, fire eller alle af de følgende kontroller: at behandle (12) den modtagne stemmeytring uden at behandle nogen anden stemmeytring eller data bestemt deraf for at bestemme, om den modtagne stemmeytring er forfalsket eller ej; at bestemme et talemodulationsindeks og/eller et forhold mellem signalintensitet i to forskellige frekvensbånd af den modtagne stemmeytring for at bestemme en fjernfeltoptagelse af en stemme; at evaluere prosodien af den modtagne stemmeytring; at kontrollere den modtagne stemmeytring for vandmærker; og at detektere afbrydelser i baggrundsstøjen.
3. Fremgangsmåde ifølge krav 1, hvor det semantiske indhold af den krævede anden stemmeytring eller en del deraf er identisk med det af den modtagne stemmeytring eller den del deraf.
4. Fremgangsmåde ifølge krav 1 eller 3, hvor den modtagne stemmeytring og den anden modtagne stemmeytring behandles (92) for at bestemme en eksakt overensstemmelse, og den anden stemmeytring behandles (91) af en passiv test for forfalskning og/eller uden at behandle nogen anden stemmeytring eller data bestemt deraf for at verificere, at den anden modtagne stemmeytring ikke er forfalsket, hvor de to behandlingstrin (91, 92) udføres uafhængigt af hinanden og/eller parallelt med hinanden, og resultaterne af behandlingstrinene kombineres logisk for at bestemme, om nogen stemmeytring er forfalsket eller ej.
5. Fremgangsmåde ifølge krav 4, hvor den logiske kombination af resultaterne af behandlingstrinene anvendes til at afgøre, om der skal udføres en levendeheds- test (98) af den talende eller ej, og hvor en levendehedstest af den talende kun udføres i tilfælde af, at de to behandlingstrin (91, 92) giver kontradiktoriske resultater vedrørende spørgsmålet, om den mindst anden stemmeytring er forfalsket eller ej, hvor levendehed bestemmes af: at vælge en sætning med et system med en pulje på mindst 100, 500,1000, 2000 eller 5000 lagrede sætninger; at kræve, at den talende siger den valgte sætning; at modtage en yderligere stemmeytring; at anvende stemmegenkendelsesmidler til at bestemme, at det semantiske indhold af den yderligere stemmeytring svarer til det af den valgte sætning; og at anvende biometriske stemmedata til at verificere, at den talendes stemme svarer til den talende, hvis identitet skal verificeres, baseret på den yderligere stemmeytring.
6. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 4, hvor trin c) omfatter undertrinet: at bestemme levendeheden (54, 75, 98) af den talende, hvor levendeheden bestemmes af: at vælge en sætning med et system med en pulje på mindst 100, 500, 1000, 2000 eller 5000 lagrede sætninger; at kræve, at den talende siger den valgte sætning; at modtage en yderligere stemmeytring; at anvende stemmegenkendelsesmidler til at bestemme, at det semantiske indhold af den yderligere stemmeytring svarer til det af den valgte sætning; og at anvende biometriske stemmedata til at verificere, at den talendes stemme svarer til den talende, hvis identitet skal verificeres, baseret på den yderligere stemmeytring.
7. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 6, hvor fremgangsmåden udfører en eller flere sløjfer (116 til 124), hvor der i hver sløjfe kræves (116), modtages (117) og behandles en yderligere stemmeytring, hvor behandlingen af den yderligere modtagne stemmeytring fortrinsvis omfatter et, to, tre eller alle af de følgende undertrin: at anvende biometriske stemmedata til at verificere (118, 119), at den talendes stemme svarer til identiteten af den talende, hvis identitet skal verificeres, baseret på den modtagne yderligere stemmeytring; at bestemme en eksakt overensstemmelse (120) af den yderligere modtagne stemmeytring med en tidligere modtaget stemmeytring; at bestemme (123) en forfalskning af den yderligere modtagne stemmeytring baseret på den yderligere modtagne stemmeytring uden at behandle nogen anden stemmeytring; og at bestemme (53) levendeheden af en talende.
8. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 7, hvor fremgangsmåden tilvejebringer et resultat, der indikerer, om den talende accepteres eller afvises.
9. Computerlæsbart medium med instruktioner lagret derpå, som udfører en hvilken som helst af fremgangsmåderne ifølge krav 1 til 9, når det afvikles på en computer.
10. Computer med et computerlæsbart medium ifølge krav 9.
