Abstract: An acquiring unit acquires information of the residence of one or more second users each having a second social media account related to a first user having a first social media account. An estimating unit estimates the residence of the first user from the information of the residence of the second user. A detecting unit detects a posting area at which the first user has posted on social media. A comparing unit compares the detected posting area with the estimated residence of the first user. A determining unit determines whether the posting area is an ordinary activity area or an extraordinary activity area for the first user based on the result of the comparison.

Abstract: An imparting unit determines whether to issue a coupon or calculates a point on the basis of a staying time in the limited area, the coupon and the point being exchangeable with an article provided in the limited area by a user who is a soon-to-be passenger to board a plane. The limited area indicates an area in which a soon-to-be passenger stays until he or she boards a plane after a security check. In addition, the staying time in the limited area indicates an elapsed time from entry to the limited area to a predetermined imparted timing. An output unit outputs, on a mobile terminal of the user, information notifying of an issuance of a coupon when the imparting unit determines to issue the coupon, or information about the point calculated by the imparting unit.
