On the other hand, it needs to be considered from different viewpoints from conventional ones. In this paper, we discuss the security of the block-based scrambled schemes against jigsaw-puzzle solvers. Block-based scrambled image encryption schemes are conventionally verified secure because the key space is large enough to be against a brute-force attack. The encrypted image has the same correlation blocks between the original ones despite the encryption. We compare divided blocks to jigsaw-puzzle pieces to verify the security of permutation-based image encryption schemes. Moreover, we conduct experiments with quantization noises image to evaluate the relation between security and noises.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-07-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2016-SPT-19"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T09:26:04.814270+00:00","created":"2025-01-19T00:39:17.450957+00:00","id":168174}
