  • Publication number: 20210004841
    Abstract: IP address attribute information in which an IP address is associated with attribute information specifiable based on the IP address is acquired from a first database 101 together with date and time information of the history. On the other hand, user identifier attribute information in which a user identifier acquired when a user terminal accesses a website is associated with an IP address and browsing related information acquired through the access to the website is acquired from a second database 201 together with date and time information of the history. Then, history information of the IP address attribute information acquired from the first database 101 and history information of the user identifier attribute information acquired from the second database 201 are integrated into a third database 301 by using the IP address and the date and time information of the history as a key, and then the attribute of the user is estimated based on the information stored in the third database 301.
