Conversational challenge-response system for enhanced security in voice only devices

An apparatus, comprising:

• at least one processor;
• and
• a computer readable storage medium having computer readable program code embodied therewith and executable by the at least one processor, the computer readable program code comprising:
• computer readable program code that receives at, a voice-enabled information handling device, voice input from a user, the voice input comprising a user command for the information handling device to perform an action;
• computer readable program code that determines whether the user command corresponds to a high risk command or a low risk command;
• computer readable program code that provides, responsive to determining that the user input corresponds to a high risk command, a first audible query and a second audible query, one of the queries corresponding to a verification request and the other of the queries corresponding to training a verification system for verification of at least one user;
• computer readable program code that receives a first voice answer input responsive to the first audible query and a second voice answer input responsive to the second audible query;
• and
• computer readable program code that performs, responsive to determining that at least one of the first voice answer input and the second voice answer input matches an answer that (i) is stored in the verification system and (ii) corresponds to the verification request, the action of the user command.

A method, comprising:

• utilizing at least one processor to execute computer code that performs the steps of:
• receiving user command input initiating a multi-turn interactive challenge session with a digital assistant, wherein the multi-turn interactive challenge session comprises provision of at least one audible output query and receipt of at least one audible answer input corresponding to the at least one audible output query;
• and
• performing an action corresponding to the user command input responsive to determining that the at least one audible answer input matches an answer corresponding to the at least on audible output query.
