Personal verification device

A personal authentication apparatus comprising:

• a vibration source provided inside a housing of a game controller;
• a vibration control section that causes said vibration source to vibrate in a plurality of different patterns when a user is gripping said housing;
• a triaxial acceleration sensor that detects a plurality of vibrations in 3-dimensional directions;
• a storage section that stores, on a user-by-user basis, history data of a plurality of occasions of a plurality of measurement data obtained by detection by said triaxial acceleration sensor of vibration generated by said vibration source that vibrates at a different voltage;
• and
• a determination section that performs personal biometric authentication by comparing and collating measurement data obtained by causing said vibration source to vibrate according to the plurality of different patterns when a user is gripping said housing with data of said storage section,
• wherein said determination section determines a user for which history data has the highest degree of similarity with measurement data among all said history data to be a candidate for being a same person.

A personal authentication apparatus comprising:

• a vibration source provided inside a housing;
• a vibration control section that causes said vibration source to vibrate and continuously changes a frequency of that vibration source when a user is gripping said housing;
• a multiaxial vibration detection section that detects vibration by said vibration source;
• an extraction section that extracts respective frequency components from a plurality of measurement data obtained by detection by said multiaxial vibration detection section for each frequency of said vibration source that changes continuously;
• a processing section that performs processing and output for each said frequency component;
• a storage section that stores processed said frequency components on a user-by-user basis;
• and
• a determination section that performs personal authentication by comparing and collating a frequency component extracted from measurement data obtained by causing said vibration source to vibrate when a user is gripping said housing with a frequency component stored in said storage section.

A program that causes a computer enabling communication with a game controller in which a vibration source and a triaxial acceleration sensor that detects a plurality of vibrations in 3-dimensional directions and a communication section are installed inside a housing to function as:

• a vibration control section that causes said vibration source to vibrate in a plurality of different patterns when a user is gripping said housing;
• a storage section that stores, on a user-by-user basis, a plurality of measurement data obtained by detection by said triaxial acceleration sensor of vibration generated by a vibration source that vibrates in a different pattern;
• and
• a determination section that performs personal biometric authentication by comparing and collating measurement data obtained by causing said vibration source to vibrate according to the plurality of different patterns when a user is gripping said housing with data of said storage section.
