Abstract: A method for protecting data based on a private set union (PSU) protocol includes: generating a Boolean vector for a first information set, based on whether or not each of a plurality of first groups that are groups of elements of the first information set stored in a first computing device is the same as each of a plurality of second groups that are groups of elements of a second information set stored in a second computing device, obtaining a random vector for the first information set as a result of shuffling performed by using the Boolean vector generated by the first computing device as an input and using order information and encryption information selected by the second computing device as inputs, and generating information on a union of the first information set and the second information set based on the random vector.

Abstract: A body for a vehicle includes a base part extending in a longitudinal direction of the vehicle and including a flange portion being open outward of the vehicle, a tubular part accommodated on and coupled to the flange portion of the base part and shaped in a pipe with a closed section, and an external garnish coupled to the base part or the tubular part to cover an external portion of the tubular part.

Abstract: A front automotive reinforcement structure for distributing impact force applied to a dash panel toward the interior and exterior of an automobile and to weaken the impact force transmitted to the inside of the automobile, thereby preventing injuries to passengers and deformation of the dash panel, wherein a lower portion constituting both left and right sides of a dash panel fixedly supported by a front side member portion is fixedly welded to an upper member supporting an upper part of the lower member and a lateral portion thereof is supported by a lateral member, whereas, between the upper member and lower member, there is a supporting lower reinforcing member along the shape thereof while a dash lower side reinforcing member is supported by welding to the lower member and to the inner side of the dash panel.
