Abstract: An information processing device obtains skeletal information which includes a location of joint in each of users who acted on a product. Then, the information processing device generates a feature quantity that characterizes an action of each of the users on a basis of the location of joint included in the skeletal information of each of the users. Then, the information processing device generates a determination index for determining a user interested in a product, by using the feature quantity of each of the users. After that, the information processing device detects a customer service target from visiting users, by using the determination index.

Abstract: A vein authentication device converts pixel values of an image, which captures an authentication site including veins, into frequency components. Moreover, the vein authentication device performs filtering of the frequency components, which are obtained by conversion of the pixel values, using a filter stored in a filter storing unit for reducing frequency components, from among low-frequency components having a lower spatial frequency than the spatial frequency of the veins and high-frequency components having a higher spatial frequency than the spatial frequency of the veins, corresponding to surface reflection of an illumination used for the authentication site. Furthermore, the vein authentication device converts the frequency components, which are subjected to filtering, back into an image. Moreover, the vein authentication device extracts vein data representing a vascular pattern of veins from the image obtained by reverse conversion. Furthermore, the vein authentication device performs vein authentication using the vein data that is extracted.
