Claims

1. A score generation means that generates an evaluation score for the target image using a target image which includes a biological image showing a predetermined region of a living organism, and target information, Image correction means for generating a corrected image by correcting the target image using the evaluation score, The system includes a display control means that controls the display of the modified image, which is generated by performing a series of processes to generate the modified image based on the target image at least once, on a display means. The aforementioned target image is displayed on the display means and includes a first image which is a photograph taken of the display image which includes the biological image. Information processing device.

2. The aforementioned target image further includes a second image, which is a photograph of the modified image displayed on the display means. The information processing apparatus according to claim 1.

3. The score generation means generates the evaluation score for the second image using the second image as the target image and the target information. The image modification means modifies the target image, the second image, using the evaluation score for the second image, thereby generating a second modified image, which is the modified image based on the second image. The display control means controls the display means to display the second modified image, which is generated by performing a series of processes at least once in which the second image is used as the target image to generate the second modified image. The information processing apparatus according to claim 2.

4. The aforementioned target image further includes the aforementioned modified image. The information processing apparatus according to any one of claims 1 to 3.

5. The score generation means generates the evaluation score for the modified image using the modified image as the target image and the target information. The image modification means modifies the target image, which is the modified image, using the evaluation score for the modified image, thereby generating a third modified image, which is another modified image based on the modified image. The display control means controls the display means to display the third modified image, which is generated by performing a series of processes at least once in which the modified image is used as the target image. The information processing apparatus according to claim 4.

6. The aforementioned modified image is an adversarial sample in biometric authentication. The information processing apparatus according to any one of claims 1 to 3.

7. The target information includes at least one of a target image that shows the predetermined target region and a target feature quantity that is a feature quantity of the target image. The evaluation score includes at least one of the following: an intermediate similarity, which is the similarity of the features used in biometric authentication; an overall similarity between the biometric image and the target image; and a PAD score used in presentation attack detection technology. The information processing apparatus according to any one of claims 1 to 3.

8. The score generation means is Image detection means for detecting the biological image from the target image, Image extraction means for extracting the detected biological image from the target image, Based on the extracted biological image, a feature extraction means extracts target features which are characteristic quantities of the biological image, The system includes a matching means that generates an overall similarity between the biological image and the target image using the extracted target features and the target features. The information processing apparatus according to claim 7.

9. One or more computers, Using a target image that includes a biological image showing a predetermined region of a living organism, and target information, an evaluation score is generated for the target image. A modified image is generated by modifying the target image using the aforementioned evaluation score. The process includes performing a series of operations to generate the modified image based on the target image at least once, and then controlling the display means to display the generated modified image. The aforementioned target image is displayed on the display means and includes a first image which is a photograph taken of the display image which includes the biological image. Information processing methods.

10. On one or more computers, Using a target image that includes a biological image showing a predetermined region of a living organism, and target information, an evaluation score is generated for the target image. A modified image is generated by modifying the target image using the aforementioned evaluation score. The system is configured to perform a series of processes at least once to generate the modified image based on the target image, thereby controlling the display means to display the generated modified image. A program in which the target image is displayed on the display means and a first image is captured of the display image including the biological image.
