Systems and methods for facilitating network voice authentication

1. A computer-implemented method for use in facilitating voice authentication of a user in connection with a network transaction, the method comprising:

prior to receiving an authorization request for a transaction:

receiving, at a computing device, an authentication request for the transaction, initiated at a voice interactive device, from a merchant plug-in (MPI) included at a merchant involved in the transaction, the authentication request including a type of the voice interactive device and a pre-authentication indicator based on voice authentication of a user by the voice interactive device or by a voice authentication service;

generating, by the computing device, a risk score for the transaction based at least in part on the type of the voice interactive device and the pre-authentication indicator;

transmitting, by the computing device, the risk score with the authentication request for the transaction to an access controller server (ACS) associated with an issuer of an account to which the transaction is directed; and

returning, by the computing device, a result response to the MPI, wherein the result response indicates permission to proceed in the transaction based on authentication of the user, the result response including an authentication code; and then,

receiving the authorization request for the transaction from an acquirer associated with the merchant, the authorization request including the authentication code representative of the voice authentication of the user; and

forwarding the authorization request to the issuer of the account.

2. The computer-implemented method of claim 1 , wherein the pre-authentication indicator includes a key signed by the voice interactive device or the voice authentication service; and

wherein the method further comprises validating the signed key prior to transmitting the risk score to the ACS.

3. The computer-implemented method of claim 1 , wherein the pre-authentication indicator includes a score; and

wherein generating the risk score includes generating the risk score based on the score associated with the pre-authentication indicator.

4. The computer-implemented method of claim 1 , wherein the authentication request further includes additional information indicative of the voice interactive device; and

wherein generating the risk score includes generating the risk score based further on the additional information.

5. The computer-implemented method of claim 1 , wherein the voice interactive device includes a smart speaker.

6. The computer-implemented method of claim 1 , further comprising:

forwarding an authorization reply, to the authorization request, to the acquirer.

7. A computer-implemented method for use in facilitating voice authentication of a user in connection with a network transaction, the method comprising:

prior to receiving an authorization request for a transaction:

receiving, at a directory server computing device, an authentication request for the transaction, initiated at a voice interactive device, from a merchant plug-in (MPI) included at a merchant involved in the transaction, the authentication request including a pre-authentication indicator based on voice authentication of a user for the transaction;

generating, by the directory server computing device, a risk score for the transaction based at least in part on the pre-authentication indicator;

determining, by the directory server computing device, whether to permit the transaction based on the generated risk score, without interacting with an access controller server (ACS) associated with an issuer of an account involved in the transaction; and

returning, by the directory server computing device, a result response to the MPI, wherein the result response indicates a permission to proceed in the transaction, the result response including an authentication code for the voice authentication of the user; and

receiving, by a payment network computing device, from the merchant, the authorization request for the transaction, the authorization request including the authentication code for the voice authentication of the user.

8. The computer-implemented method of claim 7 , further comprising validating an authentication key included in the pre-authentication indicator prior to generating the risk score; and

wherein generating the risk score is based on whether the authentication key is validated or not.

9. The computer-implemented method of claim 8 , further comprising generating the authentication code for the transaction.

10. The computer-implemented method of claim 7 , wherein the voice interactive device includes a smart speaker.

11. The computer-implemented method of claim 7 , wherein the authentication request includes information indicative of a type of the voice interactive device; and

wherein generating the risk score includes generating the risk score based on the type of the voice interactive device.

12. The computer-implemented method of claim 7 , wherein the pre-authentication indicator is based on the voice authentication of the user by the voice interactive device or by a voice authentication service.

13. The computer-implemented method of claim 7 , wherein receiving, by the payment network computing device, from the merchant, the authorization request for the transaction includes receiving, by the payment network computing device, from the merchant, through an acquirer associated with the merchant, the authorization request for the transaction.
