Abstract
An anti-communications fraud apparatus includes: an analysis unit that analyzes a voiceprint of a communication voice of a calling party; a determination unit that acquires, from a database in which the voiceprint and a degree of fraud risk are stored in association with each other, the degree of fraud risk corresponding to the voiceprint of the calling party, and determines whether the degree of fraud risk exceeds a predetermined threshold; and a notification unit that notifies that the calling party is dangerous when the degree of fraud risk exceeds the threshold.
Claims18
An anti-communications fraud apparatus, comprising:
- an analysis unit, including one or more processors, configured to analyze a voiceprint of a communication voice of a calling party;
- a determination unit, including one or more processors, configured to acquire, from a database in which the voiceprint and a degree of fraud risk are stored in association with each other, the degree of fraud risk corresponding to the voiceprint of the calling party, and
- determine whether the degree of fraud risk exceeds a threshold;
- a notification unit, including one or more processors, configured to notify that the calling party is dangerous when the degree of fraud risk exceeds the threshold;
- and
- an update unit, including one or more processors, configured to
- receive, from a called party, feedback information regarding the voiceprint of the calling party, wherein the feedback information indicates that the calling party is suspicious,
- determine that a predetermined number of pieces of feedback information is received for the voiceprint of the calling party in a predetermined period of time, and
- raise the degree of fraud risk of the voiceprint of the calling party.
An anti-communications fraud method executed by an anti-communications fraud apparatus, the method comprising:
- analyzing a voiceprint of a communication voice of a calling party;
- acquiring, from a database in which the voiceprint and a degree of fraud risk are stored in association with each other, the degree of fraud risk corresponding to the voiceprint of the calling party, and determining whether the degree of fraud risk exceeds a threshold;
- notifying, when the degree of fraud risk exceeds the threshold, that the calling party is dangerous;
- receiving, from a called party, feedback information regarding the voiceprint of the calling party, wherein the feedback information indicates that the calling party is suspicious;
- determining that a predetermined number of pieces of feedback information is received for the voiceprint of the calling party in a predetermined period of time;
- and
- raising the degree of fraud risk of the voiceprint of the calling party.
A non-transitory computer readable medium storing one or more instructions causing a computer to operate as an anti-communications fraud apparatus to execute:
- analyzing a voiceprint of a communication voice of a calling party;
- acquiring, from a database in which the voiceprint and a degree of fraud risk are stored in association with each other, the degree of fraud risk corresponding to the voiceprint of the calling party, and determining whether the degree of fraud risk exceeds a threshold;
- notifying, when the degree of fraud risk exceeds the threshold, that the calling party is dangerous;
- receiving, from a called party, feedback information regarding the voiceprint of the calling party, wherein the feedback information indicates that the calling party is suspicious;
- determining that a predetermined number of pieces of feedback information is received for the voiceprint of the calling party in a predetermined period of time;
- and
- raising the degree of fraud risk of the voiceprint of the calling party.
