TLDR
In this article, an n-dimensional biometric security system as well as a method of identifying and validating a user through the use of a automated random one-time passphrase generation were disclosed.Abstract:
There is disclosed an n-dimensional biometric security system as well as a method of identifying and validating a user through the use of a automated random one-time passphrase generation. The use of tailored templates to generate one-time phase phrase text as well as the use of update subscriptions of templates ensures a high level of security. A verification session preferably uses short, text-independent one-time pass phrases and secure audio tokens with master audio generated from an internal text-to-speech security processor. An automated enrollment process may be implemented in an ongoing and seamless fashion with a user's interactions with the system. Various calibration and tuning techniques are also disclosed.read more

Patent
Voice print identification portal
TL;DR: In this paper, a client's voice is recorded and characteristics of the recording are used to create and store a voice print when an enrolled client seeks access to secure information over a network, a sample voice recording is compared to at least one voice print.

System and method for authentication using speaker verification techniques and fraud model
John F. Sheets,Kim Wagner +1 more
TL;DR: In this article, the authors proposed a speaker verification system that allows the use of a captured voice sample attempting to reproduce a word string having a random element to authenticate the user, based on a match score indicating how closely the captured voice samples match to previously stored voice samples of the user and a pass or fail response indicating whether the voice sample is an accurate reproduction of the word string.

Authentication using biometric technology through a consumer device
John F. Sheets,Kim Wagner +1 more
TL;DR: In this article, the authors proposed a user authentication on a trusted consumer device without requiring the user to go through a formal registration process with the issuer or payment processing network, where the consumer device provides unforgeable evidence of the biometric match in the form of a biometric digital artifact.
Patent
System and method for avatar management and selection
TL;DR: In this paper, a system is configured to allow a user to select a new avatar during active communication with a remote user by detecting a face in the image, extracting features from the face, converting the facial features to avatar parameters, and transmitting at least one of the avatar selection or avatar parameters.

Device, system, and method of liveness detection utilizing voice biometrics
TL;DR: In this paper, the authors proposed a method to detect liveness using voice biometrics. But their method was based on generating a first matching score based on a comparison between a first text-dependent audio sample received at an enrollment stage, and a second text-independent audio sample at an authentication stage.

Automatic verbal information verification for user authentication
TL;DR: A new technique, verbal information verification (VIV), in which spoken utterances of a claimed speaker are verified against the key information in the speaker's registered profile automatically; to decide whether the claimed identity should be accepted or rejected is proposed.

System and method for generating challenge utterances for speaker verification
TL;DR: In this paper, the authors presented a system that generates a challenge sentence according to a rule and/or grammar, based on the voice characteristics, and prompts the second user to speak the challenge sentence.
