These factors include \"ignorance\" (unwittingly losing information), \"fault\" (performing the wrong operation or losing / stealing the portable terminal), and \"intention\" (intentionally selling information illegally). We propose a technique to preserve information in the portable terminal to prove the terminal's behavior and how information has leaked. In the proposal, we consider two problems. One is the reliability of the evidence when we applied digital forensics to the portable terminal and the other is the few calculation resources of CPU and memory, etc. Our proposal method solves these two problems by using the hysteresis signature and priority level of the evidence preservation.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"14","bibliographicVolumeNumber":"2011-UBI-29"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":72957,"links":{}}
