Authentication system, management device, and authentication method

A management device, comprising:

• a memory configured to store personal information on a user, authentication information including biometric data uniquely identifying the user, information on a plurality of services to which the authentication system is applied for the user, and a plurality of authentication types having different levels of authentication;
• a usage type determination circuit configured to determine, based on information on a service to be authenticated from the plurality of services indicated in the authentication information, a usage type corresponding to the service to be authenticated;
• an authentication type selection circuit configured to select an authentication type, from among the plurality of authentication types stored in the memory, corresponding to the usage type, wherein the authentication type is selected so that, for the usage type, a predetermined level of authentication is selected according to the service to be authenticated;
• an authentication processing circuit configured to perform, using a moving image including a face portion of the user and a voice of the user, an authentication process for the user based on the authentication type;
• and
• a notification circuit configured to notify a mobile terminal of the user of a result of authentication process, wherein
• to perform the authentication process. the authentication processing circuit is configured to perform dynamic biometric authentication including:
• a face authentication process to authenticate the user based on a face image of the user included in the moving image,
• a voice authentication process to authenticate the user based on voice information of the voice of the user included in the moving image, and
• a lip authentication process to authenticate whether movement of a lip of the user included in the moving image matches a keyword indicated by a voice of the user included in the moving image.

An authentication method in an authentication system, the authentication method comprising:

• storing, in a memory, personal information on a user, authentication information including biometric data uniquely identifying the user, information on a plurality of services to which the authentication system is applied for the user, and a plurality of authentication types having different levels of authentication;
• determining, based on information on a service to be authenticated from the plurality of services indicated in the authentication information, a usage type corresponding to the service to be authenticated;
• selecting an authentication type, from among the plurality of authentication types stored in the memory, corresponding to the usage type, wherein the authentication type is selected so that, for the usage type, a predetermined level of authentication is selected according to the service to be authenticated;
• performing, using a moving image including a face portion of the user and a voice of the user an authentication process for the user based on the authentication type;
• and
• outputting a result of authentication of the user in the authentication process, wherein
• the performing the authentication process includes dynamic biometric authentication including:
• performing a face authentication process to authenticate the user based on a face image of the user included in the moving image,
• performing a voice authentication process to authenticate the user based on voice information of the voice of the user included in the moving image, and
• performing a lip authentication process to authenticate whether movement of a lip of the user included in the moving image matches a keyword indicated by a voice of the user included in the moving image.
