Abstract: An imaging apparatus includes a light source configured to generate and output light, a stage having a measurement target thereon, a line-scan spectral imaging (SI) optical system configured to measure the measurement target using a first scale and to slopingly irradiate the light from the light source onto the measurement target in a line beam shape, divide light reflected by the measurement target, and perform imaging of the divided light, and an angle-resolved SI optical system configured to measure the measurement target at a second scale that is smaller than the first scale and configured to divide the light from the light source into monochromatic light, slopingly irradiate the monochromatic light onto the measurement target by using a reflective objective lens, and perform imaging of light reflected by the measurement target.

Abstract: Disclosed are an electronic device for obfuscating user data and a server for decoding the same. A method for controlling an electronic device according to the present disclosure comprises the steps of: acquiring a security parameter according to data transmitted to an external server; applying an obfuscation algorithm to the data by using the security parameter; and transmitting the data, to which the obfuscation algorithm has been applied, to the external server. Furthermore, in connection with a method for controlling a system comprising an electronic device for obfuscating data and a server for decoding the same according to the present disclosure, a method for controlling the electronic device comprises the steps of: inserting a fingerprint into data; generating multiple pieces of split data having a preset first size on the basis of the data into which the fingerprint has been inserted; applying an obfuscation algorithm to one piece of split data selected from the multiple pieces of split data by using a preset security parameter; and transmitting the split data, to which the obfuscation algorithm has been applied, to the server. In addition, a method for controlling the server comprises the steps of: receiving the multiple pieces of split data, to which the obfuscation algorithm has been applied, from the electronic device; acquiring at least one piece of candidate data on the basis of the received multiple pieces of split data, to which the obfuscation algorithm has been applied; and acquiring data comprising the fingerprint among the at least one piece of candidate data.

Abstract: A mask fabricating method includes dividing an outline of a first design layout for a target layer into plural segments, selecting interest segments to be biased in a direction of approaching an outline of a second design layout for a lower layer of the target layer, performing optical proximity correction for the target layer based on a first cost function given to each of normal segments and a second cost function given to each of the interest segments, and fabricating the mask corresponding to the first design layout updated based on a result of the optical proximity correction. The second cost function includes a model of a margin between each of the interest segments and the outline of the second design layout. Performing the optical proximity correction includes biasing each of the interest segments up to a boundary defined by the margin.
