System

A system comprising:

• circuitry configured to:
• detect, via a communication interface coupled to a packet-switched network, an incoming communication connection originating from identification information that is not included in identification information managed by a registration information management unit;
• acquire audio information associated with the incoming communication connection and convert the audio information into character information by executing speech recognition processing;
• generate a prompt data structure including the character information and attribute information relating to the incoming communication connection, and transmit the prompt data structure to a generative information processing model via the communication interface;
• obtain an analysis result from the generative information processing model in a predetermined structured format including a risk classification and a risk level;
• compare the analysis result with case information stored in an information storage unit and generate evaluation information;
• generate warning notification data based on the evaluation information and transmit the warning notification data as a notification data packet to a terminal device via the packet-switched network;
• receive response-operation information from the terminal device and store the response-operation information in the information storage unit;
• and
• estimate an emotional state of the user and dynamically adjust a presentation format of the warning notification data based on the emotional state.

A method performed by circuitry, the method comprising:

• detecting, via a communication interface coupled to a packet-switched network, an incoming communication connection originating from identification information that is not included in identification information managed by a registration information management unit;
• acquiring audio information associated with the incoming communication connection via an acoustic input unit, and converting the audio information into character information by executing speech recognition processing;
• generating a prompt data structure including the character information and attribute information relating to the incoming communication connection, and transmitting the prompt data structure to a generative information processing model via the communication interface;
• obtaining an analysis result from the generative information processing model, comparing the analysis result with case information stored in an information storage unit, and generating evaluation information based on the comparison;
• and
• generating warning notification data based on the evaluation information, and transmitting the warning notification data as a notification data packet to a terminal device of a user via the packet-switched network.
