Abstract: Disclosed are an access security system using a security card and a mobile terminal, and a security method for same. The present disclosure configures a mutual security function for storing an encrypted public key in a security card (E-card), and storing a private key, which can decrypt the encrypted public key, in a mobile terminal. Accordingly, a security function that is strengthened to the next level is achieved which: only allows secure access at an entrance by means of a mutual certification procedure through an NFC connection between the security card and the mobile terminal; increases the security efficiency of access management while preventing the security of a secure server from being neutralized by an information leak that has occurred due to the loss, theft, hacking, duplication, or the like of the security card; and in particular, fundamentally prevents abnormal connections by third parties to IoT equipment that can be connected to the secure server as a result of the neutralization of security.

Abstract: A platform and method for content management is disclosed. A content right management method includes receiving contents from a user, and generating a create key for a right for the contents by encrypting the contents using encryption information, in which the create key includes a copyright of the contents and a creation right of the contents.

Abstract: According to an embodiment, there is provided an extended reality (XR) system based on multimodal interfaces including a computer configured to broadcast output data including at least one device identifier (ID), at least one time limit, and at least one reproduction data to at least one extended reality output device, and at least one extended reality output device configured to receive the output data and reproduces only reproduction data corresponding to itself within the time limit based on the at least one device identifier (ID). According to this, a user can experience reproduction of five senses with a sense of reality without interruption.

Abstract: The present invention relates to a 3D printer outputting method for mounting electrical components, the method comprising a step of generating a structure forming unit structures and a step of positioning component objects on the structure. The positions of the component objects can be changed by using a coordinate system. In mounting a component object (20) on a structure (10), a coordinate system (140) is used to check for colliding or overlapping portions of the component object and to determine whether the component object (20) is supported by unit structures (15), and the merits of 3D are used to rearrange the colliding or overlapping portions or portions, that are not supported, into other dimensions. In addition, in order to automatically insert an actual component object (20), the component object is picked up by a well-known pickup device (30), and the time point and position at which a second component object (20?) is to be inserted in the first component object (20) are predetermined.

Abstract: A communication system includes a flexible circuit board, a plurality of antennas disposed on the flexible circuit board, and a radio frequency (RF) tag. A distance between the RF tag and at least one antenna among the plurality of antennas is detected based on a signal emitted by the RF tag and received by the at least one antenna. Further, a deformation of the flexible circuit board is detected based on the distance between the RF tag and the at least one antenna.
