  • Patent number: 11677744
    Abstract: A user authentication system includes a main body device and an authentication device. The main body device has an authentication code transmission requesting unit, a verification unit, and an unlocking unit. The authentication code transmission requesting unit generates an authentication code transmission request including a first value, and transmits the authentication code transmission request to the authentication device. The authentication device generates an authentication code in response to the first value in the authentication code transmission request, and transmits the authentication code to the main body device. The verification unit determines that authentication is successful if the authentication code is received from the authentication device. When the verification unit determines that the authentication is successful, the unlocking unit enables a predetermined functionality.

  • Patent number: 11647370
    Abstract: When storing captured image data in an information server, a mobile information terminal transmits related information (date and time information, location information, direction angle information, information of a distance to a subject, and user identification information) at the time of imaging to the information server. In addition, when making a request for the image data stored in the information server, current terminal information and image search conditions describing image data replay conditions are transmitted to the information server. The information server searches for corresponding image data based on the current terminal information and the image search conditions and transmits the corresponding image data to the mobile information terminal. The mobile information terminal displays the received image data on the display unit as a related image. Therefore, a user can effectively recall the memories, such as a situation or impression at the time of imaging.
