    Abstract: The disclosure is inputting a first image captured an image of an authentication target; inputting a second image captured an image of a right eye or a left eye of the target; determining whether the second image is of a left eye or a right eye of the target based on information including the first image, and outputting a determination result as left/right information in association with the second image; detecting an overlap between a region including the second image and a predetermined region in the first image; calculating a verification score by comparing characteristic information that are related to the left/right information with iris characteristic information calculated from the second image, and calculating a first weighted verification score obtained by weighting the verification score with a detection result; and authenticating a target in the second image based on the first weighted verification score, and outputting an authentication result.

    Abstract: The information processing apparatus includes: a configuration information acquisition unit that acquires object configuration information including a definition of each of one or more elements added to an image in order to indicate an object included in the image and a definition of order of the element; a user interface unit that provides a user interface being set based on a definition of the element indicated by the object configuration information according to order of the element defined by the object configuration information, in order to accept an input for specifying the element with respect to the object; and a storage control unit that controls in such a way as to store information of the element specified by the input in association with the image.

    Abstract: An information processing system includes: an acquisition unit that acquires a first image and a second image that are captured such that optical axes intersect at a predetermined point; a determination unit that determines whether or not a difference between a position of a target in the first image and a position of the target in the second image is in a predetermined range; and a control unit that performs a control of capturing an iris image of the target in a case where the difference is in the predetermined range. According to such an information processing system, the iris image of the target can be captured at appropriate timing.

    Abstract: In order to enable images of a subject of authentication who is walking to be captured at an appropriate image-capture timing corresponding to the walking state of the subject of authentication, and to acquire a clear image in which blurring of the subject of authentication is suppressed, an authentication system according to the present invention detects the position of the subject of authentication, the blurring of the body of the same being suppressed by a blurring suppressing means that suppresses blurring of the body of the subject of authentication. On the basis of the detection results, the authentication system controls an image-capture operation of an image-capture means for capturing images of the subject of authentication, and determines, on the basis of biometric information acquired from a captured image of the subject of authentication captured by the image-capture means, whether or not to authenticate the subject of authentication.

    CPC classification number: G06F21/32

    Abstract: In an authentication system, a storage unit of an authentication device constituting the authentication system stores an identification model in order to reduce a risk of leakage of personal information and shorten a response time of an authentication process. The identification model is a model generated by learning a feature amount extracted from biometric information of a registrant. A determination unit of the authentication device determines whether to authenticate a person to be authenticated based on a feature amount extracted from biometric information of the person to be authenticated using the identification model of the storage unit. A storage unit of a server constituting the authentication system stores the same identification model as the identification model used by the authentication device. An update unit of the server updates the identification model of the storage unit in response to a change of the registrant. A transmission unit transmits update information of the identification model to the authentication device in response to the update of the identification model.
