Owing to legal and ethical issues such as privacy, safety, and bias, it is crucial to adhere to the laws and respect the ethical guidelines of different countries when transferring or utilizing datasets via the Internet. Therefore, it is necessary to meticulously plan data transfer and utilization in compliance with local laws and ethical guidelines. Given the variability in legal and ethical norms across countries and the specialized knowledge required, we assume that legal and ethical checkers are implemented as independent modules that can be installed on different servers. In this study, we demonstrate how to integrate a planning agent, which utilizes an online HTN (hierarchical task network) planner, with legal and ethical checkers. We also introduce, evaluate, and compare three interaction modes between these modules, assessing the number of interactions and computation times using scenarios involving international data transfer and utilization.
