Information processing system

An information processing system comprising:

• a storage unit that stores online information related to a user and transmitted and received via a communication network, the online information including a digital ID and a face image of the user in association with each other;
• a face authentication device installed in a predetermined real space and configured to capture an image of a face of the user, collate the captured image with the face image included in the online information stored in the storage unit, and determine that a face authentication of the user is successful when both features in the captured image and the face image included in the online information are consistent;
• a behavior detection unit that detects a behavior of a user who came to the predetermined real space based on flow line data detected by a sensor installed in the real space, the flow line data including a flow line ID, a position of the user based on coordinate data detected by the sensor and a time period for which the user stays in a predetermined area;
• an association unit that associates the user who came to the real space with a user whose online information is stored, based on data obtained from an action of the user performed in the real space;
• and
• a user processing unit that executes predetermined processing with respect to the user based on the detected behavior of the user and the online information of the user who came to the real space, the predetermined processing including at least one of the following:
• transmitting introduction information or sales promotion information regarding a product or a service to a user terminal of the user by using the digital ID as a destination address;
• transmitting the introduction information or the sales promotion information regarding the product or the service to a digital signage in a vicinity of the position of the user;
• or
• transmitting a current position of the user acquired by the sensor and information for instructing to provide special treatment to the user to a terminal of a store staff,
• wherein the association unit, upon receiving data indicating that the face authentication is successful from the face authentication device, associates the digital ID, which is associated with the face image, with the flow line ID.
