實務上發生許多案件,因為當事人不知該如何蒐集數位資料,導致官司敗訴的不幸結果,也發生過第三人提出之數位資料,遭當事人質疑之情況。諸如本文所提到的劉○○案、呂副總統與新新聞的官司、日本堀江電郵事件等;這些案件都是因為當事人無法利用數位採證,或無法取得關鍵數位資料,而導致敗訴,或政治人物道歉下台之結果。 近幾年,許多學術單位、政府機關積極發展數位鑑識領域,並期盼為司法機關研擬一套標準作業流程,以提昇數位資料採證的準確度及可信度,以作為犯罪偵查之輔佐依據。惟數位資料的來源除了執法機關的主動調查外,還包括訴訟當事人及第三人之提出,若後者未能重視數位資料之採證流程,恐怕無法取得被法院所能接受之數位資料。 我國目前有關偵查主體蒐集數位證據之標準化作業流程,已有許多論文進行探究;然而,針對非偵查主體的部份,尚未見有學者從事此一領域之研究,致使許多實際個案中,當事人或第三人往往未能有一套遵循的準則得以適用,造成不利之訴訟結果。 為此,本論文希望從實務工作經驗中,輔以過去法律學之基礎,以及在本所學習之資訊管理相關知識,尋求一套非偵查主體之數位資料採證標準作業程序,以作為各企業組織、政府機關及個人之參考依據,強化數位資料之提出,達到儘量發現真實之訴訟目的。
During the practical investigation, many lawsuit cases have lost due to the fact that the litigants failed to understand the importance of digital forensics and how to properly handle the digital evidence. In recent years, many academic institutions and government agencies have actively devoted to advance the field of digital forensics and expected to develop a set of standard operating procedures as the guideline for law enforcement. The standard operating procedure will not only improve the accuracy and non-repudiation of digital evidence in order to assist law enforcement agencies but also provide as guidance for any non law enforcement third parties involved in criminal investigation. The court may not admit the electronically stored information as legit digital evidence if the litigant did not establish a solid standard operating procedure regarding how the digital evidence was obtained. This thesis focuses on establishing a set of digital forensics standard operating procedures for the non- law enforcement parties. The standard operating procedure will be taken as the referential procedure for various enterprises and governmental agencies to strengthen the results of digital forensics and reveal the fact in front of the court.
