Problems solved by technology
[0008] However, as mentioned above, the sample delivery model is desired when it is used for mobile applications where the network environment cannot be secured at the time of authentication, or for gate management that needs to ensure availability even in the event of a network failure.
When trying to implement revocable biometric authentication in the sample transfer model, it is necessary to transfer parameters and samples to the client side, so there is a problem that the risk of the characteristic quantity being restored while the parameters and samples are leaked increases

Embodiment Construction
[0028] Embodiments of the sample transfer type revocable biometric authentication system and method thereof of the present invention will be described in detail below with reference to the accompanying drawings.
[0029] In this embodiment, the following system is taken as an example for illustration. The system manages samples in a unified manner in the sample management server, and at the same time logs in to the client terminal through the transfer of samples to realize revocable generation authentication. For example, consider that employees in an enterprise share client terminals (such as notebook PCs) and / or authentication devices (such as mobile finger vein authentication devices), and lend arbitrary client terminals and / or authentication devices when employees (users) are on business trips. device to use. The user's sample and parameters are transmitted at the time of lending, and the user can be authenticated by revocable biometric authentication even in an offline en...

In a biometric authentication system, a delivery server includes a parameter conversion unit which generates, by converting the parameter, a parameter for delivery, a template conversion unit which generates, by converting the template, a template for delivery, and a delivery unit which delivers the template for delivery and the parameter for delivery to one of the client terminal and an authentication device; the authentication device includes a sensor which obtains biometric information on a registered user, a feature quantity obtaining unit which obtains a feature quantity from the biometric information, and a feature quantity conversion unit which generates, by converting the feature quantity using the parameter for delivery, a converted feature quantity; and the client terminal includes a match determination unit which determines, by comparing the converted feature quantity with the template for delivery, whether or not the converted feature quantity and the template for delivery match.
Description
technical field [0001] The present invention relates to a biometric authentication system for authenticating a person using biometric information of an individual and a method thereof. Background technique [0002] Compared with the authentication by card or password, the biometric authentication of personal authentication based on biological information has the advantage of not being lost, forgotten, or stolen, and can realize personal authentication with high convenience and anti-counterfeiting. A general biometric authentication system acquires biometric information of a user at the time of initial login, and extracts and registers information called a characteristic amount. This login information is referred to as a sample. At the time of authentication, the biometric information extracted from the user is again compared with the previously registered sample to confirm whether it is the person. [0003] In a biometric authentication system used by multiple users, sampl...
