  • Publication number: 20240126853
    Abstract: High-accuracy multimodal biometric authentication of a plurality of body organisms is achieved while suppressing postural fluctuation when the plurality of body organisms are captured. An authentication system stores feature quantities for body organisms in association with users and performs biometric authentication on the basis of images from a capture device. The capture device photographs a first body organism of a first user during a first period and captures a second body organism and a third body organism of the first user during a second period. The authentication processing device calculates a first feature quantity from the first body part photographed during the first period, respectively calculates a second feature quantity and a third feature quantity from the second body organism and the third body organism captured during the second period, and compares with the feature quantities for the body organisms of each user stored at the storage device.

  • Patent number: 7866886
    Abstract: In the pouch of the present invention in which a pouring spout is formed by means of a heat-sealed part and a non-heat-sealed part by heat sealing plastic films, the inside surfaces of the films that form the portion of the boundary area between the heat-sealed part and non-heat-sealed part of the pouring spout passage on the side of the non-heat-sealed part contact each other so that no gaps are left in a closed state. Accordingly, even if the pouch is suspended with the pouring spout down following the opening of the pouring spout, the leakage of the contents such as a liquid or the like accommodated in the interior of the pouch from the pouring spout a small amount at a time can be securely prevented.
