Application of interaction modeling for lambda triggering of authorization

A method for step-up authentication for using spoken passphrases, the method comprising:

• receiving, by an interface device, a conversational request for an action;
• deriving, by the interface device, an intent from the conversational request by comparing the intent to a collection of intents stored by an interaction model, the deriving including determining the intent requires step-up authentication;
• initiating, by the interface device and based on the determination, a step-up authentication process that includes a response using conversational artificial intelligence (AI) that includes a warning that an additional authentication step is required, the additional authentication step including an interaction with a virtual private cloud (VPC);
• receiving, by the interface device and in response to the warning, a spoken input that includes a passphrase, the passphrase having been communicated to a computing device of a user from a passphrase service of a datacenter communicatively connected to the interface device, the passphrase service having generated the passphrase using a spoken passphrase dictionary;
• determining, by the interface device, a spoken intent of the spoken input an initiation intent for an interaction with the VPC;
• generating, by the interface device, an authorization intent using an interaction model;
• transmitting, by the interface device, the authorization intent and the spoken input to the VPC, wherein the authorization intent and spoken input are transmitted to the datacenter using one or more application programming interfaces (APIs) for validation of the spoken input;
• and
• receiving, by the interface device from the passphrase service of the datacenter, a confirmation validating the spoken input, the spoken input having been validated by the passphrase service of the datacenter to include the passphrase generated by the passphrase service of the datacenter, wherein the confirmation facilitates authenticating the user and authorizing the action of the conversational request.

A conversational interface system for step-up authentication using spoken passphrases, the system comprising:

• at least one processor;
• a communication interface communicatively coupled to the at least one processor;
• and
• a memory device storing executable code that, when executed, causes the processor to:
• receive, by an interface device, a conversational request for an action, the conversational request being received after performing an initial authentication of a user, the initial authentication being based on user information of the user;
• derive, by the interface device, an intent from the conversational request by comparing the intent to a collection of intents stored by an interaction model, the deriving including determining the intent requires step-up authentication;
• initiate, by the interface device and based on the determination, a step-up authentication process that includes a response using conversational artificial intelligence (AI) that includes a warning that an additional authentication step is required, the additional authentication step including an interaction with a virtual private cloud (VPC);
• receive, by the interface device and in response to the warning, a spoken input that includes a passphrase, the passphrase having been communicated to a computing device of the user from a passphrase service of a datacenter communicatively connected to the interface device, and based thereon determine, by the interface device, that an interaction with the virtual private cloud is to be initiated;
• initiate, by the interface device, the interaction with the VPC;
• generate an authorization intent using an interaction model, the authorization intent including at least a portion of the user information of the user;
• transmit, by the interface device and via one or more application programming interfaces (APIs), the authorization intent and the spoken input that includes the passphrase to the VPC for validation of the passphrase;
• receive, by the interface device from the passphrase service of the datacenter, a confirmation validating the spoken input, the spoken input having been validated by the passphrase service of the datacenter to include the passphrase generated by the passphrase service of the datacenter;
• and
• authenticate, based on receiving the confirmation, the user to facilitate implementing the action of the conversational request.
