Abstract: Provided is an author verifying apparatus and method which can receive contests stored online or offline by a user, and register a verifiable credential in a decentralized network, the verifiable credential including metadata having information on at least a part of the attribute and hash value of the contents, at least some of the contents, and the DID of the user. Thus, the author verifying apparatus and method can objectively verify the creator of contents stored online or offline without an error, regardless of an environment such as the place in which the contents are stored.

Abstract: A goods distribution tracking apparatus and method may request an issue of a verifiable credential including the DID of a user and distribution-related information on goods distributed by the user, receive the verifiable credential issued in response to the issue request, output the received verifiable credential in the form of encoded identification information, accurately and objectively track a goods distribution process without exposing the personal information of the user and the like, and enable a user, involved in each distribution process, to pay only the cost required for using the corresponding distribution process.

Abstract: Disclosed is an emergency detection and response system using LED-lighting modules. The emergency detection and response system using LED-lighting modules, according to the present invention, comprises: a plurality of LED-lighting modules having an emergency sensor for sensing an emergency and a communication sensor; a communication network for, if an emergency is detected by the emergency sensor, receiving emergency detection signals transmitted via the communication sensor and providing the emergency detection signals to an operation unit; a control unit for controlling the LED-lighting modules according to control signals received from the operation unit or a specific emergency detection signal among the emergency detection signals; and a cloud platform for building, as a database, the emergency detection signals received from the communication network or the control signals corresponding to the emergency detection signals and transmitting an early warning signal on the basis of the received signals.

Abstract: The present invention relates to a method and apparatus for providing application service in a mobile communication system. A method in which a base station provides application service comprises: a step of receiving a request for application service from a mobile terminal; and a step of providing the mobile terminal with the requested application service on the basis of application service information pre-stored in the base station and/or application service information received from an application server, in accordance with whether or not the application service information corresponding to the requested application service is pre-stored in the base station.

Abstract: Provided are a broadcast receiving apparatus and an audio output method thereof, and more particularly, a broadcast receiving apparatus and an audio output method thereof in which an audio included in a broadcast signal that is received through a selected broadcast channel and then decoded is output to a built-in speaker. Some embodiments provide a broadcast receiving apparatus and an audio output method thereof in which, among audio, video, and/or additional information included in a broadcast signal received through a selected broadcast channel corresponding to a control signal received from a remote controller, the audio is selectively output in response to status information of a connected display apparatus.
