Document Type and Number:
WIPO Patent Application WO/2022/230311
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a determination device capable of accurately determining whether or not user IDs in different user databases indicate the same user. An ID determination device 100 comprises a position vector generation unit 102 that generates a position vector from position information corresponding to a user ID managed in a user management database such as a position information data DB 300, and an action vector generation unit 101 that generates an action vector from purchase information (action information) corresponding to a user ID managed in a payment data DB 200 that is a user management database different from the aforementioned user management database (e.g. position information DB data 300). An ID determination unit 104 determines identity between a user with the user ID associated with the position vector and a user with the user ID associated with the action vector on the basis of the position vector and the action vector.
