Abstract

In authentication based on an image region read from a surface of a target object, authentication based on a position corresponding to the image region is executed. An authenticating server 2 receives an image region as an authentication target read from a surface of a target object possessed by a user together with an authentication request from the user, identifies a position corresponding to the image region as the authentication target and one reference image region corresponding to the image region as the authentication target in a plurality of previously stored reference image regions read from respective surfaces of a plurality of target objects, and executes authentication in response to the authentication request based on the identified position.

First claim

1 . An authenticating apparatus comprising:
a receiving unit that receives an image region as an authentication target read from a surface of a target object possessed by a user together with an authentication request from the user; an identifying unit that identifies a position corresponding to the image region as the authentication target and one reference image region corresponding to the image region as the authentication target in a plurality of previously stored reference image regions read from respective surfaces of a plurality of target objects; and an authenticating unit that executes authentication in response to the authentication request based on the identified position.

2 . The authenticating apparatus described in claim 1 , wherein the identifying unit identifies a position in the one reference image region corresponding to the image region as the authentication target in the plurality of reference image regions.

3 . The authenticating apparatus described in claim 2 , further comprising an authentication request determining unit that determines whether or not the authentication request is valid based on whether or not the identified position in the reference image region is included in a used image region including a position identified in past for the reference image region by the identifying unit,
wherein, if the authentication request determining unit has determined that the authentication request is not valid, the authenticating unit determines authentication failure in response to the authentication request.

4 . The authenticating apparatus described in claim 3 , wherein, if the authentication request determining unit has determined a predetermined number of times that the authentication request received from the same user by the receiving unit is valid, the authenticating unit determines authentication success in response to the authentication request received from the user.

5 . The authenticating apparatus described in claim 3 , further comprising a registering unit that registers identification information to be linked to each of at least parts of the plurality of reference image regions,
wherein the receiving unit receives identification information together with the authentication request, and wherein the authentication request determining unit determines whether or not the received authentication request is valid based on whether or not the registered identification information matches the received identification information.

6 . The authenticating apparatus described in claim 4 , further comprising a registering unit that registers identification information to be linked to each of at least parts of the plurality of reference image regions,
wherein the receiving unit receives identification information together with the authentication request, and wherein the authentication request determining unit determines whether or not the received authentication request is valid based on whether or not the registered identification information matches the received identification information.

7 . The authenticating apparatus described in claim 3 , further comprising a reading position determining unit that determines a reading position of an image region to be read from the target object possessed by the user,
wherein the receiving unit receives the image region as the authentication target read based on the reading position determined by the reading position determining unit.

8 . The authenticating apparatus described in claim 4 , further comprising a reading position determining unit that determines a reading position of an image region to be read from the target object possessed by the user,
wherein the receiving unit receives the image region as the authentication target read based on the reading position determined by the reading position determining unit.

9 . The authenticating apparatus described in claim 7 , wherein the reading position determining unit determines a reading position of an image region to be read next time from the target object possessed by the user in the one reference image region corresponding to the image region as the authentication target excluding the used image region.

10 . The authenticating apparatus described in claim 8 , wherein the reading position determining unit determines a reading position of an image region to be read next time from the target object possessed by the user in the one reference image region corresponding to the image region as the authentication target excluding the used image region.

11 . The authenticating apparatus described in claim 9 , wherein, if the authentication request has been determined to be valid by the authentication request determining unit, the reading position determining unit determines the reading position of the image region to be read next time from the target object possessed by the user.

12 . The authenticating apparatus described in claim 10 , wherein, if the authentication request has been determined to be valid by the authentication request determining unit, the reading position determining unit determines the reading position of the image region to be read next time from the target object possessed by the user.

13 . The authenticating apparatus described in claim 9 , wherein, if the identified position is included in the used image region, the reading position determining unit determines the reading position of the image region to be read next time from the target object possessed by the user.

14 . The authenticating apparatus described in claim 10 , wherein, if the identified position is included in the used image region, the reading position determining unit determines the reading position of the image region to be read next time from the target object possessed by the user.

15 . The authenticating apparatus described in claim 1 , wherein, if a maximum value of correlation values between local regions set for each of the plurality of reference image regions and the image region as the authentication target is equal to or greater than a first threshold serving as a criterion for similarity and less than a second threshold serving as a criterion for match, the identifying unit identifies a position in a local region corresponding to the maximum value as a position in the one reference image region corresponding to the image region as the authentication target.

16 . The authenticating apparatus described in claim 15 , wherein, if the maximum value of the correlation values between the local regions set for each of the plurality of reference image regions and the image region as the authentication target is less than the first threshold or equal to or greater than the second threshold, the identifying unit does not identify the position in the one reference image region, and
wherein, if the position in the reference image region has failed to be identified by the identifying unit, the authenticating unit determines authentication failure in response to the received authentication request.

17 . The authenticating apparatus described in claim 1 , wherein an image size of the reference image region is greater than an image size of the image region as the authentication target.

18 . An authenticating system comprising a terminal apparatus and an authenticating apparatus, wherein the terminal apparatus includes
a reading unit that reads a surface of a target object possessed by a user, and a unit that transmits an image region as an authentication target read by the reading unit together with an authentication request from the user, and wh
