Abstract
A method and system for secure speaker authentication between a caller device and a first device using an authentication server are provided. The system comprises extracting features into a feature matrix from an incoming audio call; generating a partial i-vector, wherein the partial i-vector includes a first low-order statistic; sending the partial i-vector to the authentication server; and receiving from the authentication server a match score generated based on a full i-vector and another i-vector being stored on the authentication server, wherein the full i-vector is generated from the partial i-vector.

A method for secure speaker authentication between a caller device and a first device using an authentication server, comprising:
- extracting features into a feature matrix from an incoming audio call;
- generating a partial i-vector, wherein the partial i-vector includes a first low-order statistic;
- sending the partial i-vector to the authentication server;
- and
- receiving from the authentication server a match score generated based on a full i-vector and another i-vector being stored on the authentication server, wherein the full i-vector is generated from the partial i-vector.
A method for securely authenticating a speaker between a caller device and a first device, comprising:
- generating a user account including a user identifier based on at least one metadata element received from a caller device associated with an audio input;
- receiving a partial i-vector generated by the first device based on at least the audio input;
- generating a full i-vector based on the partial i-vector;
- and
- associating the user account with the full i-vector.
A non-transitory computer readable medium having stored thereon instructions for causing a processing circuitry to perform a process, the process comprising:
- generating a user account including a user identifier based on at least one metadata element received from a caller device associated with an audio input;
- receiving a partial i-vector generated by a first device based on at least the audio input;
- generating a full i-vector based on the partial i-vector;
- and
- associating the user account with the full i-vector.
A system for securely authenticating a speaker between a caller device and a first device, comprising:
- a processing circuitry;
- and
- a memory, the memory containing instructions that, when executed by the processing circuitry, configure the system to:
- generate a user account including a user identifier based on at least one metadata element received from a caller device associated with an audio input;
- receive a partial i-vector generated by the first device based on at least the audio input;
- generate a full i-vector based on the partial i-vector;
- and
- associate the user account with the full i-vector.
