  • Publication number: 20230321988
    Abstract: A recording apparatus includes a recording portion, a liquid container portion containing a liquid to be supplied to the recording portion, a body in which the recording portion and the liquid container portion are mounted, and a housing that houses the body. The body can be changed in position between a closed position and an open position in a position-change direction intersecting with a vertical direction. The body, when located at the closed position, is housed inside the housing. The body, when located at the open position, protrudes from the housing in a first position-change direction of the position-change direction. The liquid container portion includes a container space containing the liquid to be supplied to the recording portion, and a liquid inlet through which the liquid can be poured into the container space. The liquid inlet is exposed when the body is located at the open position.

  • Patent number: 8443201
    Abstract: 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.

  • Patent number: 8412940
    Abstract: At registration time, feature data array for registration is generated from biometric information, and position correction template and comparison template. At authentication time, feature data array for authentication is generated from biometric information acquired by the client, and converted feature data for position correction obtained by converting the feature data array for authentication is transmitted to the server. The server detects position correction amount of the feature data array for authentication relative to the feature data array for registration using the position correction template and the converted feature data, and transmits the position correction amount to client. Client corrects the feature data array for authentication and transmits the converted feature data array for comparison to the server.

  • Patent number: 8320640
    Abstract: 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.

  • Patent number: 8177314
    Abstract: A printing apparatus includes a head which discharges color inks and into which clear ink that prevents the head from being clogged and white ink are selectively filled. A selection portion communicates either of a white or a clear ink container with the head. A controller executes a first switching from a second filled state where the head is filled with clear ink to a first filled state where the head is filled with white ink by shifting from a state where the clear ink container is communicated with the head to a state where the white ink container is communicated with the head. A second switching is executed from the first filled state to the second filled state by shifting from a state where the white ink container is communicated with the head to a state where the clear ink container is communicated with the head.

  • Publication number: 20120005736
    Abstract: In the client, a feature quantity extraction unit extracts a feature quantity from biometric information of a user. A feature quantity conversion unit converts the feature quantity by a one-time parameter. In the first server, a parameter DB stores a parameter in association with the ID. A data generation unit generates data based on the parameter corresponding to the ID transmitted from the client. In the second server, a template DB stores a template to which the feature quantity of the biometric information of the user is converted by the parameter, in association with the ID. A template conversion unit generates a one-time template by converting the template corresponding to the ID transmitted from the first server. Then, a match determination unit compares the converted feature quantity transmitted from the client or the data transmitted from the first server with the one-time template to determine whether they match or not.

  • Publication number: 20110314285
    Abstract: When a registration station appends an anonymous ID (AID), a linking validity of the anonymous ID and actual user ID (UID) is assured for an application businessperson in the case of applying to use a biometric authentication. Specifically, a biometric authentication service system includes a biometric authentication server, an application server, a registration station server and a client server, for holding a hash value alone of personal information (P) in the registration station server, supplying again the personal information on applying to use a template (T) for the application server, collating the hash with the previously held hash, and verifying that the user applying to use the template is identical with the user registered the biologic information in the registration station server, in addition, secret information (S) different for every user is added to the personal information to generate unique data and identify the user correctly.

  • Patent number: 7936905
    Abstract: A personal authentication method is provided for authenticating a user by cross-relation between an enrolled image and a verification image of biometric information of the user. Upon registration of the biometric information, the method generates a filter for scrambling the image and an inverse filter thereof, and applies the filter to the enrolled image generated from the biometric information to generate a registration template which is then stored to a memory. Upon authentication of the user, the method applies the inverse filter to the verification image generated from the biometric information collected from the user, and then verifies the identity of the user based on cross-relation between the verification image after application of the inverse filter and the registration template.
