Abstract: The present disclosure relates to a method for performing vehicle position recognition using a geomagnetic sensor by calibrating the geomagnetic sensor on the basis of a geomagnetic sensor value stored in a database in advance before entrance to an area in which position recognition through a GPS is impossible. Thus, it is possible to accurately detect a position of a vehicle using the geomagnetic sensor even in a structure such as a tunnel.

Abstract: The present disclosure relates to a contact verification technology based on signal similarity, and an apparatus of contact verification receives and stores spatiotemporal signal information capable of specifying time and space from a plurality of user equipments (UEs), extract the spatiotemporal signal information of a specific user among the stored spatiotemporal signal information, configure the extracted spatiotemporal signal information of the specific user as reference spatiotemporal signal information, and compare similarity between the reference spatiotemporal signal information and the other stored spatiotemporal signal information, and determine whether or not there is contact between the specific user and another user based on the similarity.
