Revision report

We would like to thank our shepherd and the anonymous reviewers for their careful and insightful comments , which helped us to improve the overall quality of the paper. We have revised the paper to comply with the guidance of the shepherd and the comments of the reviewers. The revised portions of the paper are highlighted in red. Our revisions for the six categories are summarized below. 1 HOP is overstated as a novel contribution. The reviewers and shepherd are right to point out that HOPs are not a completely new approach and are similar to some existing methods. To address these comments, we have rephrased the description of HOPs in Section 1 and 7 and mentioned the link between HOPs and existing methods in Sections 1 and 6. The description of HOPs is rephrased so that HOPs are no longer described as " new " or " novel " in Section 1, paragraph 4 and Section 7, paragraph 1. The link between HOPs and behavioral biometrics is now mentioned in the introduction in Section 1, paragraph 4 and again in the related work in Section 6.2, paragraph 1. 2 Provide more exact details about the experiment. The reviewers and shepherd commented on several details of the experiments that were not discussed in the paper. To address these comments, we have added more details on demographics, experimental setup, tasks performed in the game, human characters, bot characters, and bot profiles in Section 3.2. In total, three new paragraphs were added: 1. The demographics of the 30 human players are detailed in Section 3.2, paragraph 2. The details include age, gender, and computer gaming experience. 2. The experimental setup is further detailed in Section 3.2, paragraph 3. The details include where the traces were collected, i.e., in the lab or on the players' home computer, what types of tasks are performed by the human players in the game, and the human players' character classes and levels. 3. The bot profiles and characters are detailed in Section 3.2, paragraph 4. The details include how the locations of the profiles differ, and the bots' character classes and levels. Additionally, we have clarified the description of our experiments with BP neural networks in Section 5.2, last paragraph. Lastly, we have added two new graphs in Section 5, last paragraph to illustrate the distribution of decision time for bots and humans. 3 Acknowledge the experimental …
