However, there is a problem in that the authentication takes a long time and the authentication accuracy is not good when the individual authentication is performed only by the fingerprint. In order to solve this problem, there is disclosed a device that utilizes not only a fingerprint but also physical characteristics other than the fingerprint for personal authentication. For example, Japanese Patent Laid-Open No. 1-
The invention disclosed in Japanese Patent Laid-Open No. 276376 “Pattern Image Processing Device” (hereinafter referred to as a prior invention) discloses a device that utilizes a fingerprint and a width of a finger for personal authentication.

す。Information such as the user's password and fingerprint, the width of the finger, etc. is stored in advance in the IC card 45. When personal authentication is performed, the fingerprint from the IC card 45 is read via the reading / writing device 46. The width information of the finger is read out, and the fingerprint, the width information of the finger, and the information of the finger read by the camera 41 are collated by the control unit 43. (According to the description of the prior invention, page 7, lines 5-11). FIG. 5 is a plan view showing the width detector 38, and the same reference numerals as those in FIG. 4 denote the same parts.

目視照合作業が必要とされ、自動認証は困難であった。As described above, in the conventional personal authentication device, the process of authenticating the person by collating the fingerprint of one finger is performed. However, the person using the fingerprint characteristic information of one finger is used. There is a limit to the accuracy of automatic authentication of whether or not it is necessary to perform visual verification of the image itself by a fingerprint collation expert to determine the person in question, and automatic authentication is difficult.

To facilitate understanding, the flow is represented by partial names and information names for executing the steps instead of being represented by program steps. FIG. Next, the operation will be described. The subject registers in advance the palm print characteristic information of the subject in the stored palm print portion 14 as a file corresponding to the recitation number. Also in this registration, each part shown in FIG.
The operation unit 12, the palm image input unit 13, the setting unit 21, the palm image input / cutout unit 22, and the feature extraction unit 23 are used.

By instructing the palm image input / cutout unit 22 via the unit 21, the plurality of storage regions designated by the palm image input / cutout unit 22 are sequentially cut out and given to the feature extraction unit 23 as input palm images. The extraction unit 23 extracts the characteristics of each input palm image. Then, when the features of all the input palm images are extracted, the recitation number is input from the operation unit 12, and the recitation number is associated with the storage part information and the feature information of each storage part to store the palm pattern part 14. Remember.

の部位の入力掌画像を入力する。Next, the authentication operation will be described. When the recitation number is input from the operation unit 12, the setting unit 21 reads the part information and the feature information corresponding to the recitation number, and sets it as the storage part information and the storage feature point information in the register in the control unit 15. Then, the palm image input / cutout unit 22 cuts out the part indicated by the part stored as the storage part information from the palm image and inputs it as the input palm image. Since a plurality of regions are usually shown as the stored region information, the palm image input / cutout unit 22 sequentially inputs the plurality of regions as input palm images, and the feature matching unit 24 for one input palm image. After the process in step is finished, the input palm image of the next part is input.

A line of x = 0 and a line of y = 0 indicating the coordinate axes of the mounting surface are described. Then, as shown in FIG. 3, the five fingers are placed in parallel with each other as much as possible so that the center line of the middle finger is parallel to the line of x = 0 and the tip of the middle finger is in contact with the line of y = 0.

If the site information such as 3 is matched at the coordinate position of the center point of the site, the error of the site information position at the time of registration and at the time of authentication can be reduced. Further, it is difficult to place the thumb on the other finger in parallel, and only the thumb is naturally placed on the other finger at a predetermined angle. Therefore, the position of the thumb is often deviated between the registration and the authentication, so that the site information is not set for the part of the thumb. Further, the cutout range is set to be 2 cm square at the time of registration and 2.5 cm square at the time of authentication.
