Abstract: Provided are a location tracking method capable of controlling setting of a short-range wireless communication terminal based on search results of assistant terminals adjacent to a communication relay device when a short-range wireless communication terminal, which is an intensive tracking target, enters an area in which the short-range wireless communication terminal can communicate with the communication relay device, and a server and a program using the location tracking method.

Abstract: Disclosed is a foldable helmet for protecting a user's head, the foldable helmet includes a main body, and two pairs of segments that are connected to the main body in a foldable manner and face each other with the main body therebetween in a first direction and a second direction perpendicular to the first direction, respectively, wherein the two pairs of segments are folded in different directions.

Abstract: Provided is a verification level control method, the method comprises checking a history of verification or a history of re-authentication of a verification target, setting an abnormal suspicious area according to a change in frequency of access to a partial area within an access permission area of the verification target, based on the checked verification history or re-authentication history and verifying the verification target by reflecting whether the verification target is located in the set abnormal suspicious area, wherein the re-authentication is performed in an explicit authentication method in which the verification target needs to perform a separate action for the re-authentication.

Abstract: Provided is a method of operating a gateway performing communication between a server and a wireless communication terminal, the method comprises receiving, by the gateway, identification information of the wireless communication terminal and sensing data related to the wireless communication terminal and controlling, by the gateway, setting of the wireless communication terminal based on identification information of the gateway and both the received identification information of the wireless communication terminal and the sensing data, wherein the identification information of the gateway comprises information about an area in which the gateway is installed.

Abstract: Provided are a method of verifying a target person, the method comprises collecting non-identifying personal data for a target person, determining a classification type for each of a plurality of classification criteria from the collected non-identifying personal data and performing verification based on a result of comparing the determined classification type for each of the plurality of classification criteria with a reference type for each of the plurality of classification criteria.

Abstract: Provided are a liveness verification method, the method comprises collecting identification information of a verification target, determining whether there is pre-stored non-identifying personal data corresponding to the collected identification information of the verification target, and performing liveness verification on biometric information collected from the verification target using different types of data according to whether there is the pre-stored non-identifying personal data.
