【摘要】：隨著手機(jī)、PDA等各種移動(dòng)電子設(shè)備的廣泛使用,利用手機(jī)進(jìn)行的各類犯罪活動(dòng)日益猖獗。手機(jī)取證技術(shù)的相關(guān)研究對(duì)于打擊與手機(jī)相關(guān)的各類犯罪活動(dòng)、維護(hù)社會(huì)穩(wěn)定具有重要意義。 手機(jī)取證不同于一般的計(jì)算機(jī)取證,這是由于：一是手機(jī)操作系統(tǒng)種類多、接口不統(tǒng)一、驅(qū)動(dòng)及連接方式不同等多種差異性的存在；二是通信網(wǎng)絡(luò)又在不斷的改進(jìn)變化之中。上述原因決定了手機(jī)取證技術(shù)一定是多樣化的,并且需要不斷的發(fā)展,以保證跟上手機(jī)和通信網(wǎng)絡(luò)技術(shù)進(jìn)步的步伐。因此對(duì)手機(jī)取證技術(shù)研究具有重要的現(xiàn)實(shí)意義。 本文分析研究了當(dāng)前手機(jī)取證技術(shù)的現(xiàn)狀和發(fā)展趨勢(shì),從三層架構(gòu)的角度使用UML工具重點(diǎn)剖析了TULP2G取證軟件的結(jié)構(gòu)并深入分析其設(shè)計(jì)思想,在此基礎(chǔ)上使用基于軟件開發(fā)的原則和模式對(duì)其設(shè)計(jì)存在的缺陷提出系統(tǒng)框架改進(jìn)方案,通過改進(jìn)前后的靈活性和性能對(duì)比,論述改進(jìn)方案的優(yōu)越性。 本論文利用改進(jìn)后的TULP2G取證軟件獲取取證數(shù)據(jù),提取出的數(shù)據(jù)具有如下特點(diǎn)：數(shù)據(jù)量較大；存在很多無關(guān)信息；看不出數(shù)據(jù)之間的相關(guān)性。為了便于取證人員對(duì)取證數(shù)據(jù)進(jìn)行相關(guān)性分析,本文使用基于向量時(shí)鐘的數(shù)據(jù)相關(guān)性模型,在此模型基礎(chǔ)上設(shè)計(jì)出可視化相關(guān)性工具,使得由TULP2G軟件提取出的數(shù)據(jù)經(jīng)過該可視化工具處理后更加形象、直觀,便于取證人員獲取有用信息。
[Abstract]:With the widespread use of various mobile electronic devices such as mobile phones and PDAs , various kinds of criminal activities using mobile phones are increasingly rampant . The relevant research of mobile phone access technology is of great significance to combat all kinds of criminal activities related to mobile phones and to maintain social stability . Mobile phone evidence is different from general computer forensics , which is due to many different kinds of different kinds of mobile phone operating systems , different interfaces , different driving and connection modes , and the continuous improvement of communication network . The above reasons determine that mobile phone forensics technology must be diversified and need to be continuously developed to keep up with the progress of mobile phone and communication network technology . Therefore , it has important practical significance to study the technology of mobile phone forensics . This paper analyzes the present situation and developing trend of the current mobile phone forensics technology , analyzes the structure of the TULP2G certification software from the perspective of the three - tier architecture and deeply analyzes its design thought . On the basis of this , the defects of the design of TULP2G based on the principles and modes of software development are used to improve the system framework improvement scheme , and the advantages of the improved scheme are discussed through the improvement of the flexibility and the performance comparison before and after the improvement . This paper takes advantage of the improved TULP2G forensic software to obtain the forensic data . The extracted data has the following characteristics : large amount of data , many irrelevant information , and no correlation between the data . In order to facilitate the correlation analysis between the evidence data and the evidence data , a visual correlation tool is designed on the basis of this model , so that the data extracted by the TULP2G software is more vivid and visual after being processed by the visualization tool , so that useful information can be obtained conveniently .
