摘要： There is obtained a laser processing method by which an excellent shape of a cut surface can be achieved and an increase in cost can be suppressed. A laser processing method includes the steps of: preparing a material to be processed; and forming a modified area in the material to be processed, by irradiating the material to be processed with laser beam. In the aforementioned step, pulsed laser beam having a continuous spectrum is focused with a lens, thereby forming a focusing line constituted by a plurality of focuses that are obtained by predetermined bands forming the continuous spectrum of the laser beam, and the material to be processed is irradiated with the laser beam such that at least a part of the focusing line is located on a surface of the material to be processed, thereby forming the modified area on an axis of the focusing line.

摘要： The present invention captures user's biometric data during enrollment and converts it by a given conversion parameter to create a template. It creates verification information for the conversion parameter, and enrolls it in an authentication server together with the template. The conversion parameter is stored in an IC card or the like for issuance to the user. During authentication, the authentication server verifies that the authentication terminal knows the conversion parameter, using conversion parameter verification information. Next, the authentication terminal converts user's biometric data newly captured by a conversion parameter to create matching information, and transmits it to the authentication server. The authentication server matches the matching information with the template to determine whether the user is a principal.

摘要： In additional enrollment of a template in a biometric authentication system, the template is automatically enrolled on the basis of a plurality of authentication results to assure a user's convenience and security. A post-migration authentication server receives a first template and a second template from a post-migration authentication terminal, performs authentication on the basis of the comparison result between the received first template and the user's preliminarily first enrolled template, and provisionally enrolls the first template and the second template. It repeats the reception, authentication, and provisional enrollment and calculates a match probability from a plurality of comparison results of the provisionally first enrolled templates, determines whether or not to store a second enrolled template on the basis of the match probability, and automatically enrolls the second template in the post-migration authentication server.

摘要： In a biometrics authentication system inputting biometric information and outputting a user ID, speedup of 1:N matching on the side of server is achieved when cancelable biometrics authentication is realized in which matching is carried out. During registration, similarity of a feature to a dummy feature is searched and the feature is transformed by using a transform parameter corresponding to a nearest neighboring dummy feature. The transformed feature and a group ID are transmitted to the server and the server registers the transformed feature at the group in a DB. During authentication, like the registration process, similarity search of a feature is carried out and the feature is transformed by using transform parameter corresponding to a nearest neighboring dummy feature. The transformed feature and group ID are transmitted to the server. The server executes 1:1 matching between a template a the group in the DB and the transformed feature.

摘要： A template sharing processing is performed between a first authentication server and a second authentication server. A client terminal generates two parameter differences, one of which is sent to the first authentication server, and the other to the second authentication server. The first authentication server transforms an already-registered template with the received parameter difference to create a temporary template and sends the temporary template to the second authentication server. The second authentication server transforms the received temporary template with the already-received parameter difference to create and register therein a further transformed template. A storage medium stores therein only a single master key for generating a parameter.
