A fingerprint authenticating system includes a fingerprint registering unit and a fingerprint collating unit. The fingerprint registering unit takes a first fingerprint data indicating a first portion of a first fingerprint from a first fingerprint sensor, registers said first fingerprint data to a memory unit, and takes a second fingerprint data indicating a second portion of a second fingerprint from a second fingerprint sensor. The fingerprint collating unit collates said second fingerprint data with said first fingerprint data to confirm whether or not said first fingerprint is equal to said second fingerprint. Here, an area of the first portion is equal to or larger than an area of the second portion.

1. Field of the Invention
The present invention relates to a fingerprint authenticating system, a fingerprint authenticating method and a fingerprint authenticating program. More particularly, the present invention relates to a technique for using a small fingerprint sensor and carrying out a fingerprint authentication.
2. Description of the Related Art
FIG. 1 is a view showing the configuration of the fingerprint authenticating system according to the embodiment of the present invention;
FIG. 2 is a view showing the block diagram of the fingerprint authenticating system according to the embodiment of the present invention;
FIG. 3 is a view showing the scan condition of the fingerprint authenticating system according to the embodiment of the present invention;
Embodiments of the present invention will be described below with reference to the attached drawings. A fingerprint authenticating system according to an embodiment of the present invention is invented by paying attention to the following point. That is, the registration of a fingerprint is carried out in only the first trial when a usage of an apparatus including this fingerprint authenticating system is started, and the collation of the fingerprint is carried out for each usage of the apparatus
That is, the registration of the fingerprint is carried out only one time. Thus, even if the sweep reading operation for reading the fingerprint while sliding a finger with respect to a fingerprint sensor is carried out, this operation does not impose a burden on a user. Also, the deposition of contaminant caused by the operation for sliding the finger is little. On the other hand, the fingerprint of the entire finger is obtained by the sweep reading operation. Hence, it is possible to obtain the fingerprint picture (image) having much information.
On the other hand, the collation of the fingerprint carried out for each usage of the apparatus does not impose the burden on the user, since a still reading operation is carried out for making the finger static with respect to the fingerprint sensor and then reading the fingerprint. Also, there is no deposition of the contaminant caused by the operation for sliding the finger. Moreover, the fingerprint picture having the much information is registered. Hence, at the time of the collation, even if the information amount is not much such as the partial fingerprint of the finger obtained by the still reading operation, it is possible to carry out the collation at a high precision.
