  • Division of Information and Communication, Baekseok University, 115, Anseo-dong, Cheonan, Choongnam, Korea
  • Departmentof Computer Information, Woosong University, 17-2, Jayang-dong, Dong-gu, Daejeon, Korea


Objectives: There have been occurred many quantitative and qualitative changes in computer software industry. Some of the changes are negative aspects. We studied an intellectual property rights among negative aspects. Methods/Statistical Analysis: The subject of this study is actual cases to occur in real situation. We choose a GIS program. Fake names in this paper are used for related companies. The company A’s AA program and company B’s BB program have the four similarities and plagiarism such as import/export, space calculation, storage manager and display. Therefore, we choose appraisal standards on the following programs the four objections in this study. Findings: We analyzed and conducted in the procedure from setting of appraisal items to evaluation of appraisal. Firstly, five items were set in the step of determining items to analyze similarity of the two programs. As the step of adding relative significance on appraisal items on the previous step, significance of each item is added in our principles. Degree of copying on the items is calculated by our principles. As the last step of calculating overall degree of copying on the two programs are calculated by our principles in this paper. The overall copying degree showed very low value of 5.17 Percentage. This means that the copying rate is very low or none had taken place. Improvements/Applications: We introduce the principles needed to calculate the degree of the copying in programs. And we also showed a procedure to analyze similarity and copying.
