【摘要】：通过缉毒侦查来打击毒品犯罪活动,是解决毒品问题泛滥的最直接手段。由于毒品犯罪案件是隐性案件,一般没有明确的犯罪现场,也没有特定的报案人、受害人,具有明显的智能化、网络化、隐蔽化特征,犯罪手段又多种多样,增加了侦查发现的难度。收集、获取毒品犯罪证据是缉毒侦查的关键环节,也是确保打击效果的前提,但毒品犯罪的证据类型单一、即时性强、容易毁坏,导致毒品犯罪证据发现难、收集难、认定难,成为一直困扰司法部门的难题。在毒品犯罪案件中应用电子取证技术,可以丰富侦查手段,拓宽证据类型,成为解决毒品犯罪案件侦查发现难、证据来源少、取证困难的一种利器。因此,在当前信息社会背景下,开展毒品犯罪案件中电子取证技术研究,对提高打击成效、遏制毒品蔓延具有重要的实践意义。论文根据毒品犯罪案件的特点,利用电子取证技术的理论和方法,开展电子取证技术在毒品犯罪案件中的应用研究。主要研究内容如下：论文总结了国内外电子取证技术的研究现状,分析电子取证技术在禁毒领域的实际应用情况,针对应用过程中存在的系统性研究成果不多、取证与侦查脱节、取证缺乏主动性等不足,结合毒品犯罪案件的规律特点,专题研究电子取证技术在毒品犯罪案件中的应用,系统归纳毒品犯罪案件中电子证据的来源和分类,对常见的手机证据、网上交易证据、电子邮件证据和网络聊天证据的取证方法进行了详细分析。针对司法实践的需求,利用静态取证技术和动态取证技术,进行毒品犯罪案件电子证据综合取证分析模型设计研究,设计了一种适合毒品犯罪案件调查取证的分析模型。该模型从毒品犯罪案件入手,逐一分析了数据收集、数据处理、数据分析、证据提取以及证据提交各模块的功能和实现过程,并把蜜罐技术的思想和诱惑侦查手段相结合,提高了打击毒品犯罪活动的主动性。在此基础上,设计了一种适合毒品犯罪案件侦查与取证的系统架构。
[Abstract]:The most direct way to solve the problem of drug abuse is to crack down on drug crime through drug detection. Because drug crime cases are hidden cases, there is generally no clear crime scene, no specific informant, no victim, with obvious intelligence, networking, covert characteristics, and a variety of criminal methods. It increases the difficulty of detection. Collecting and obtaining evidence for drug-related crimes is a key link in drug detection and also a prerequisite for ensuring the effectiveness of the crackdown. However, the type of evidence for drug-related crimes is single, immediate and easy to destroy, leading to the difficulty of finding, collecting, and determining evidence for drug-related crimes. It has been a difficult problem for the judiciary. The application of electronic forensics in drug crime cases can enrich the investigative techniques, widen the types of evidence, and become a sharp weapon to solve the problem of difficult investigation and discovery of drug crime cases, less sources of evidence and difficulty in obtaining evidence. Therefore, under the background of the current information society, it is of great practical significance to carry out the research on electronic forensics in drug crime cases to improve the effectiveness of the crackdown and to curb the spread of drugs. According to the characteristics of drug crime cases, this paper makes use of the theory and method of electronic forensics to study the application of electronic forensics in drug crime cases. The main research contents are as follows: this paper summarizes the current research situation of electronic forensics technology at home and abroad, analyzes the actual application of electronic forensics technology in the field of drug control, aiming at the lack of systematic research results in the process of application. Evidence collection and investigation, lack of initiative and other deficiencies, combined with the characteristics of the law of drug crime cases, special research on the application of electronic forensics in drug crime cases, systematically summed up the source and classification of electronic evidence in drug crime cases, The common evidence of mobile phone, online transaction, e-mail and internet chat are analyzed in detail. In order to meet the needs of judicial practice, this paper studies the design of a comprehensive forensic analysis model for electronic evidence in drug crime cases by using static and dynamic forensics techniques, and designs an analytical model suitable for the investigation and collection of drug crime cases. Starting with drug crime cases, the model analyzes the functions and implementation process of each module of data collection, data processing, data analysis, evidence extraction and evidence submission, and combines honeypot technology with the means of enticement investigation. We have increased our initiative in cracking down on drug crimes. On this basis, a system structure suitable for drug crime investigation and evidence collection is designed.
