Description

  The present invention relates to an unmanned contract machine, an unmanned contract system, an iris registration device, and an iris registration system that acquire iris data from a customer who makes a contract with a financial institution.

When a conventional unmanned transaction system makes a contract with an unmanned contract machine, it sends the customer's contract application form and identification image obtained by the unattended contract machine to the center terminal in the center, which is displayed on the screen. When the details of the application form are confirmed by the staff at the center, the iris photographing camera of the unmanned contractor takes a picture to obtain the customer's iris data and sends the obtained iris data to the center terminal. Then, it is confirmed that the same iris data as the iris data received by the center terminal is not registered in the iris database of the center, and the iris data of the received eye image is registered in the iris database (see, for example, Patent Document 1). ).

  However, in the above-described conventional technology, when the eyelids cover the iris by, for example, narrowing the eyes when photographing the iris, the amount of iris data decreases, resulting in a different result from the iris data in the normal state. If a customer who has signed a contract with a financial institution and registered his / her iris data in the iris database intentionally closes his eyes by photographing the iris using a fake ID, etc. There is a problem that iris data may be newly registered in the iris database and double registration by the same person may be performed.

  The present invention has been made to solve the above problems, and an object thereof is to provide means for preventing double registration by the same person.

In order to solve the above problems, the present invention provides an eye image acquisition means for acquiring a customer's eye image for acquiring customer's iris data, a face image acquisition means for acquiring a customer's face image, and the eye image A determination ratio storage means for storing a determination ratio of a ratio of the eye opening width of the eye image to the eye opening width of the face image for determining that sufficient iris data cannot be obtained from the face image; and the face image means for storing the customer's face image acquired by the acquisition means reads the face image the storage, means for measuring the opening width of the eyelid, the opening width of the eyelid eye image acquired by the first image acquisition unit Means for measuring, means for calculating the ratio of the eye opening width of the eye image to the eye opening width of the face image, and the ratio of the calculation result is less than the determination ratio read from the determination ratio storage means , the decision Characterized in that it comprises means for the error.

  As a result, the present invention compares the eyelid opening width of the eyelid photographed in a natural state where the customer is not aware of photographing for iris data acquisition and the eyelid opening width of the eye image photographed for iris data acquisition. This makes it possible to prevent the customer from making a contract by covering the iris with a cocoon and preventing double registration by the same person.
