First Claim
1. An electronic system for authenticating a user of an electronic service, said system comprising:
- at least one server apparatus; and
a hardware processor configured to store, for a number of users, a plurality of personal voiceprints each of which being linked with a dedicated visual, audiovisual or audio cue, for challenge-response authentication of the users, wherein the cues are user-selected, user-provided or user-created,pick, upon receipt of an authentication request associated with a claim of an identity of an existing user of said number of users, a subset of cues for which there are voiceprints of the existing user stored, and provide the cues for representation to the user as a challenge,receive sound data incorporating a contact microphone signal, comprising a throat microphone signal, in addition to a mouth microphone signal, comprising a close-speaking microphone signal, the sound data being indicative of voice response uttered by the user to the represented cues,determine on the basis of the sound data, the represented cues and voiceprints linked therewith and the existing user, whether the response has been uttered by the existing user of said number of users, wherein the sound data indicative of the voice responses uttered to the represented cues are matched as concatenated against a concatenated voiceprint established based on the voiceprints linked with the represented cues and the existing user, and provided that this is the case,elevate the authentication status of the user as the existing user, regarding at least the current communication sessionwherein the hardware processor is further configured to utilize, based on the obtained data indicative of the location of the user, the estimated location of the user as an authentication factor.

1. An electronic system for authenticating a user of an electronic service, said system comprising:
-
at least one server apparatus; and a hardware processor configured to store, for a number of users, a plurality of personal voiceprints each of which being linked with a dedicated visual, audiovisual or audio cue, for challenge-response authentication of the users, wherein the cues are user-selected, user-provided or user-created, pick, upon receipt of an authentication request associated with a claim of an identity of an existing user of said number of users, a subset of cues for which there are voiceprints of the existing user stored, and provide the cues for representation to the user as a challenge, receive sound data incorporating a contact microphone signal, comprising a throat microphone signal, in addition to a mouth microphone signal, comprising a close-speaking microphone signal, the sound data being indicative of voice response uttered by the user to the represented cues, determine on the basis of the sound data, the represented cues and voiceprints linked therewith and the existing user, whether the response has been uttered by the existing user of said number of users, wherein the sound data indicative of the voice responses uttered to the represented cues are matched as concatenated against a concatenated voiceprint established based on the voiceprints linked with the represented cues and the existing user, and provided that this is the case, elevate the authentication status of the user as the existing user, regarding at least the current communication session wherein the hardware processor is further configured to utilize, based on the obtained data indicative of the location of the user, the estimated location of the user as an authentication factor. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. An electronic device for authenticating a person, the electronic device comprising:
-
a voiceprint memory configured to store, for a number of users including at least one user, a plurality of personal voiceprints, each of which being linked with a dedicated visual, audiovisual or audio cue, for challenge-response authentication, wherein the cues are user-selected, user-provided or user-created, an authentication hardware processor configured to pick, upon receipt of an authentication request associated with a claim of an identity of an existing user of said number of users, a subset of cues for which there are voiceprints of the existing user stored, and represent the cues in the subset to the person as a challenge, and a response provision hardware processor for obtaining sound data incorporating a contact microphone signal, a throat microphone signal, in addition to a mouth microphone signal, the sound data being indicative of the voice response uttered by the person to the represented cues, whereupon the authentication hardware processor is configured to determine, on the basis of the sound data, the represented cues and voiceprints linked therewith and the existing user, whether the response has been uttered by the existing user of said number of users, wherein the sound data indicative of the voice responses uttered to the represented cues are matched as concatenated against a concatenated voiceprint based on the voiceprints linked with the represented cues and the existing user, and provided that this is the case, to elevate the authentication status of the person as the existing user, wherein the electronic device is further configured to utilize, based on the obtained data indicative of the location of the user, the estimated location of the user as an authentication factor. - View Dependent Claims (12, 13, 14)

15. A method for authenticating a subject person to be executed by one or more electronic devices, comprising:
-
storing, by a hardware processor, for a number of users, a plurality of personal voiceprints each of which linked with a dedicated visual, audiovisual or audio cue, for challenge-response authentication of the users, cues being user-selected, user-provided or user-created; picking, by the hardware processor, upon receipt of an authentication request associated with a claim of an identity of an existing user of said number of users, a subset of cues for which there are voiceprints of the existing user stored, to be represented as a challenge; receiving, by the hardware processor, response incorporating sound data incorporating a contact microphone signal, a throat microphone signal, in addition to a mouth microphone signal, the sound data being indicative of the voice response uttered by the person to the represented cues, wherein the voice response is captured utilizing a throat microphone; determining, by the hardware processor, on the basis of the sound data, the represented cues and voiceprints linked therewith and the existing user, whether the response has been uttered by the existing user, wherein the sound data indicative of the voice responses uttered to the represented cues are matched as concatenated against a concatenated voiceprint established based on the voiceprints linked with the represented cues and the existing user, and provided that this is the case; and elevating, by the hardware processor, the authentication status of the person acknowledged as the existing user according to the determination, wherein the estimated location of the user, based on the obtained data indicative of the location of the user, is further utilized as an authentication factor. - View Dependent Claims (16, 17, 18)
