(The Onion Router) is an anonymous network technology that is widely used in the implementation of anonymous networks. Using Tor's Onion Service, websites can be operated while keeping IP addresses and other information that can lead to the identification of the operating source secret. Since the Onion Service is sometimes used to operate illegal Web services, many studies have analyzed the contents of Web sites operated using the Onion Service. However, few studies have conducted large-scale analysis of metadata. In this study, we attempted to clarify the feature distribution of Onion Service by collecting Onion Domain on a large scale and analyzing HTTP responses. As a result, we collected approximately 200,000 Onion Domains, or about a quarter of the total, and found that their HTTP responses had a distinctly different distribution from the surface web. Farthermore, it is suggested that a small number of operators may be hosting a large number of Onion sites using the virtual host function.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"522","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"513","bibliographicIssueDates":{"bibliographicIssueDate":"2025-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"66"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/0002001670","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"80578"},"created":"2025-03-10T02:50:19.486311+00:00","id":2001670,"links":{}}
