  • Publication number: 20230289429
    Abstract: An authentication system that performs authentication by limiting a use permission period of a function of a device and provides permission for use includes a determination unit configured to determine that the permission for use of the device has started, and a limitation unit configured to impose a limitation so that rewinding of the time does not exceed a predetermined range in response to a request for changing the time in a body of the device in a case where the determination unit determines that the permission for use has started.

  • Patent number: 7920726
    Abstract: An image processing method and apparatus for reproducing moving image data, the method and apparatus comprising detecting defects in receiving moving image data, determining the priority of each defect if there are a plurality of defects in at least one frame of the received moving image data, and performing interpolation for each defect based on the determined priority.

  • Patent number: 7415141
    Abstract: A signature authentication device is disclosed. Even when there are variations in an input hand-written signature during the registration of the signature or during the authentication of the signature, the signature authentication device easily registers or authenticates the signature. The signature authentication device allows a user to re-register the signature without a risk that sensitive information stored in a computer is monitored by someone else. A plurality of pieces of authentication signature data for a single user is stored. If comparison for authentication between input signature data and at least a single piece of the plurality of the pieces of the authentication signature data is successful, then the authentication is regarded as successful. During signature registration, the plurality of the pieces of the authentication signature data is stored in a storage unit.

  • Patent number: 7263211
    Abstract: An information processing apparatus detects the sampling rate of a coordinate input device, and standardizes the writing data which is input from the coordinate input device based on the detected sampling rate. The standardized writing data is further used for signature verification or for handwritten character recognition. The information processing apparatus provides precise signature verification or handwritten character recognition even if signatures or handwritten characters for handwritten character recognition are input using digitizers having different processing rates.

  • Patent number: 7197117
    Abstract: A coolant passage is formed inside the rotary shaft while an air passage is formed inside the casing. A mechanical seal is arranged between the coolant passage and the air passage. Leakage cooling water, which has leaked in the form of vapor from the mechanical seal, is relegated radially outwardly along with air by the action of a rotary vane, which is disposed in the air passage, and finally flows out of an air outlet. A coolant sensor may be provided to early detect the leakage water.

  • Patent number: 7093197
    Abstract: A signature processing method determines, when displaying an input signature on a display unit, whether a predetermined condition is satisfied. When it is determined that the predetermined condition is satisfied, the signature on the display unit is displayed in a manner that it is difficult for others to discern the signature.

  • Patent number: 7035406
    Abstract: An entered signature is compared with registered signature data to calculate an evaluation value, and when the evaluation value for the entered signature is within the allowable range for successful authentication, it is determined whether aging has occurred. When aging is determined to have occurred, a warning message is displayed to urge re-registration of the signature. According to such a configuration, it is possible, when a change in signature is caused by aging, to avoid circumstances in which authentication becomes suddenly impossible.
