This paper empirically investigated the factors that may affect art forgery, using 5,130 authentication request data drawn from Korean Art Appraisal Board (KAAB) during 2003 and 2012. Living status of artists and trade frequency of artworks of the artists were considered as explanatory variables that may affect authentication requests and forgery ratio. We found that artists' death has significantly positive impacts on both authentication requests and forgery ratio, while trade frequency of artworks of the artists has the impact only on authentication requests. These results imply that art forgery may have multidimensional characteristics.

In this paper, we have designed an optical measurement system for authenticity of paintings. Using a simple and compact optical measurement system, the surface characteristics of paintings could be measured, and we obtained information about paintings. First, the paintings that were painted in various colors could give characteristic information on the color of paintings. Second, tomographic information about the surface of a painting could be obtained, using a line laser. To assess the reliability of the optical measurement system, forgeries looking like the originals were created, and we could distinguish the originals from the forgeries through experiment. Thus, we could obtain data about the paintings and create a numerical database.

본 논문에서는 각종 문화콘텐츠의 진위와 표절을 검출하는 방법론에 대해 제안하고자 한다. 이를 위해 기존의 문화콘텐츠에 대한 표절과 위작 감정이 어떤 방법으로 되어 왔는가에 대해 살펴보고 본 방법과의 비교,고찰을 행하고자 한다. 실험 대상은 우선적으로 미술품등에 대해 수행하였으며 이를 토대로 개발하고 있는 시스템이 표절 감정 및 위작 감정에 유용하게 도움을 줄수 있는 방법임을 밝히고자 한다. 끝으로 현재까지 실험이 수행된 부분에 대해 서 실험 결과를 제시하고자 한다.

There is a problem that unknown paintings are sophisticated in the level of forgery, making it difficult for even experts to determine whether they are genuine or counterfeit. These problems can be suspected of forgery even if the genuine product is submitted, which can lead to a decline in the value of the work and the artist. To address these issues, in this paper, we propose a system to classify chromaticity data among extracted data through objective analysis into quadrants, extracting comparisons and intersections, and estimating authors of unknown paintings using XRF and hyperspectral spectrum data from corresponding points.

In this paper, survey of technical methods for protecting intellectual properties and proposal of art works plagiarism detection are accomplished. For this, in this paper, a survey of technical methods for inspecting of program source code plagiarism, analysis of natural languages plagiarism types and existing inspection methods are accomplished Also, author verification system and plagiarism detection about ancient literatures or art works is proposed because of ancient literatures or art work are important in the aspect of cultural properties control, protecting of author's intellectual property and owner's property estimation.
