An Algorithm Integrating and Updating Rights Management Information on Public Domain Images

The public domain sites provide various types of public domain works and displays Rights Management Information (RMI) for them. Users may use public domain works in accordance with RMI as specified by the author. However, users who do not understand RMI for a public domain work can be disputed by copyright infringement. To solve this problem, it is necessary to provide users with the accurate and most updated information of RMI on public domain works. To solve these problems, in this paper, we propose an algorithm that extracts and analyzes the information needed to update the latest RMI and correct the wrong or duplicate RMI information in various public domain sites. The proposed algorithm has been verified using 10,000 data for the accuracy of extraction and consistency of updates. The experiment shows that the automatic updating and integration was accomplished for 99.96% of data and only 0.04% of data required to be verified manually.
