  本文選題：計(jì)算機(jī)犯罪 + 數(shù)字化偵查取證��； 參考：《福州大學(xué)》2009年碩士論文

【摘要】：計(jì)算機(jī)犯罪帶來(lái)了極壞的破壞作用和社會(huì)影響，它直接危害到國(guó)家的政治、經(jīng)濟(jì)、文化等各方面的正常秩序。在全社會(huì)的信息安全意識(shí)淡薄和司法的滯后等諸多因素的影響下，計(jì)算機(jī)犯罪被偵查取證并且能提起訴訟的非常少。原因在于，，數(shù)字化偵查取證棘手，許多計(jì)算機(jī)犯罪案件由于證據(jù)缺乏而放棄了起訴。若采用計(jì)算機(jī)辨析學(xué)方法，組織多方面人力進(jìn)行數(shù)字化偵查取證，搜尋確認(rèn)犯罪嫌疑人和犯罪事實(shí)并進(jìn)行起訴，就有可能從根本上杜絕這類(lèi)犯罪。在當(dāng)前的計(jì)算機(jī)網(wǎng)絡(luò)安全形勢(shì)嚴(yán)峻的情況下，實(shí)施并推廣數(shù)字化偵查取證具有十分重要的意義。 本文研究對(duì)象為數(shù)字化偵查取證技術(shù)。首先介紹了課題的選題背景和研究意義，并簡(jiǎn)單介紹了數(shù)字化偵查取證技術(shù)的國(guó)內(nèi)外研究現(xiàn)狀。接著對(duì)數(shù)字化偵查工作平臺(tái)的網(wǎng)絡(luò)平臺(tái)拓?fù)浞桨冈O(shè)計(jì)、網(wǎng)絡(luò)系統(tǒng)軟件和數(shù)據(jù)庫(kù)系統(tǒng)的選型、網(wǎng)絡(luò)的安全性設(shè)計(jì)等方面進(jìn)行研究和設(shè)計(jì)。然后對(duì)數(shù)字化偵查工作平臺(tái)的平臺(tái)基礎(chǔ)功能、平臺(tái)集成功能、平臺(tái)辦公自動(dòng)化子系統(tǒng)的設(shè)計(jì)、網(wǎng)絡(luò)設(shè)備管理監(jiān)控等方面進(jìn)行詳盡的探討和設(shè)計(jì)分析。針對(duì)具體的數(shù)字化偵查取證，以Windows系統(tǒng)為例，對(duì)操作系統(tǒng)的數(shù)字化偵查取證技術(shù)進(jìn)行了研究；并結(jié)合網(wǎng)絡(luò)中常見(jiàn)的犯罪行為，分析研究計(jì)算機(jī)網(wǎng)絡(luò)的數(shù)字化偵查取證技術(shù)手段。最后對(duì)將基于計(jì)算機(jī)處理的中文切詞技術(shù)應(yīng)用于數(shù)字化電子證據(jù)后期分析做了初步研究。 本論文的創(chuàng)新點(diǎn)是設(shè)計(jì)了一個(gè)數(shù)字化偵查取證平臺(tái)模型；研究總結(jié)并提出了Windows系統(tǒng)及計(jì)算機(jī)網(wǎng)絡(luò)中數(shù)字化電子證據(jù)的收集技術(shù)；分析了計(jì)算機(jī)中文切詞技術(shù)在數(shù)字化偵查中的應(yīng)用價(jià)值和可行性。
[Abstract]:The computer crime has brought the extremely bad destruction function and the social influence, it directly endangers the national politics, the economy, the culture and so on the normal order. Under the influence of the weak information security consciousness of the whole society and the lag of judicature and other factors, the computer crime is investigated to obtain evidence and can file a lawsuit very few. The reason is that digital investigation is difficult to obtain evidence, many computer crimes due to lack of evidence to abandon the prosecution. If we use the method of computer discrimination, organize various manpower to carry out digital investigation and collection of evidence, search and confirm the suspect and the fact of the crime and prosecute, it is possible to put an end to this kind of crime fundamentally. Under the severe situation of computer network security, it is of great significance to implement and popularize digital investigation and forensics. The research object of this paper is digital investigation and forensics technology. Firstly, it introduces the background and significance of the topic, and briefly introduces the domestic and foreign research status of digital investigation and forensics technology. Then the network platform topology scheme design, network system software and database system selection, network security design and so on are studied and designed. Then, the basic functions of the platform, platform integration function, the design of the platform office automation subsystem, network equipment management and monitoring and so on are discussed and analyzed in detail. Taking Windows system as an example, this paper studies the digital investigation and forensics technology of the operating system, and analyzes and studies the digital investigation and forensics technology of the computer network in the light of the common criminal behavior in the network. Finally, a preliminary study is made on the application of Chinese word segmentation technology based on computer processing to the later analysis of digital electronic evidence. The innovation of this paper is to design a model of digital investigation and forensics platform, summarize and put forward the collection technology of digital electronic evidence in Windows system and computer network. This paper analyzes the application value and feasibility of computer Chinese word cutting technology in digital investigation.
