Abstract: Disclosed is an image encoding method. The method includes deriving a motion refinement candidate from among motion information of spatial neighboring blocks, motion information of a temporal neighboring blocks, predefined motion information, and motion information that most frequently occurs in a reference picture, performing a motion information refinement on the derived motion refinement candidate, and generating a prediction block of a current block by using the motion refinement candidate having undergone the motion information refinement.

Abstract: An apparatus and method for processing sensitive data. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to, in an unprotected data area, read sensitive data from a storage device and transmit the same to a protected data area using the sensitive-data storage endpoint of the protected data area; to, in the protected data area, process the sensitive data using at least one endpoint when a command for a sensitive-data service requested by a client device is received from the unprotected data area; and to, in the unprotected data area, transmit the result of processing the sensitive data to the client device.

Abstract: The present invention relates to a method for protecting MU-MIMO (Multi User-Multiple Input Multiple Output) data through a multi-RTS/CTS frame exchange in a MU-MIMO based wireless communication system. The method of the present invention comprises: a process where an indicator for VHT data protection is added to an RTS frame, using the structure of an RTS/CTS frame for an existing legacy terminal during the multi RTS/CTS frame exchange; a process where an access point designates and then transmits the duration period of the RTS frame while transmitting the RTS frame; and a process where wireless terminals up to the (n−1)th terminal designate the duration period of the CTS frame as ‘0’ and send the designated duration period, while only the n-th wireless terminal designates NAV for data protection.
