This chapter is meant to give the state of the art of forensic geochemistry and recent advances. In terms of forensic organic geochemistry, detecting mature organic matter including polluting hydrocarbons follows an experimental procedure by using recent experimental analytical techniques. However, the interpretation of these results needs an understanding of the geochemical context to make a distinction between the natural and the human made origin of oil. Infrared data coupled with statistical analyses would have an important relevance for the detection of the pollution during the Anthropocene, which is marked an increasing human pollution reaching the level of environmental crimes. In terms of nuclear and isotopic forensic geochemistry, recent studies provided that nuclear forensics considers the fact that some measurable parameters or signatures are distinctive.
本章旨在介绍法医地球化学的现状和最新进展。在法医有机地球化学方面,利用最新的实验分析技术,检测包括污染碳氢化合物在内的成熟有机质遵循实验程序。然而,对这些结果的解释需要了解地球化学背景,以区分石油的自然来源和人为来源。红外数据加上统计分析对于探测人类世期间的污染具有重要意义,人类世标志着人类污染日益增加,已达到环境犯罪的程度。在核和同位素法医地球化学方面,最近的研究表明,核法医考虑到一些可测量的参数或特征是独特的。

The detection of different types of forgery manipulation including seam-carving in JPEG images is a hot spot in image forensics. Seam carving was originally designed for content-aware image resizing. It is also being used for forgery manipulation. It is still very challenging to effectively identify the seam carving forgery under recompression. To address the highly challenging detection problems, this chapter introduces an effective approach with large feature mining. Ensemble learning is used to deal with the high dimensionality and to avoid overfitting that may occur with some traditional learning classifier for the detection. The experimental results validate the efficacy of proposed approach to detecting JPEG double compression and exposing the seam-carving forgery while the JPEG recompression is proceeded at the same quality and a lower quality, which is generally much harder for traditional detection methods. The methodology introduced in this chapter provides a strategy and realistic approach to resolve the highly challenging problems in image forensics.
对JPEG图像中各种伪造手法的检测是图像取证领域的研究热点。接缝雕刻最初是为内容感知图像调整大小而设计的。它也被用于伪造操作。如何有效地识别再压缩下的缝刻伪造,仍然是一个非常具有挑战性的问题。为了解决极具挑战性的检测问题,本章介绍了一种使用大特征挖掘的有效方法。集成学习用于处理高维问题,避免了传统学习分类器可能出现的过拟合问题。实验结果验证了该方法在对JPEG图像进行相同质量和较低质量的再压缩时,能够有效地检测出JPEG图像的双重压缩并暴露出缝雕伪造,这是传统检测方法难以做到的。本章介绍的方法为解决图像取证中极具挑战性的问题提供了一种策略和现实的方法。

Deep learning-based investigation mechanisms are available for conventional forensics, but not for IoT forensics. Dividing the system into different layers according to their functionalities, collecting data from each layer, finding the correlating factor, and using it for pattern detection is the fundamental concept behind the proposed intelligent system. The authors utilize this notion for embedding intelligence in forensics and speed up the investigation process by providing hints to the examiner. They propose a novel cross-layer learning architecture (CCLA) for IoT forensics. To the best of their knowledge, this is the first attempt to incorporate deep learning into the forensics of the IoT ecosystem.

A fire investigation is a difficult and challenging task. An investigator's basic task at a fire scene is two-fold: first, to ascertain the origin of the fire and, second, to closely investigate the site of origin and try to determine what triggered a fire to start at or near that spot. Usually, an investigation would begin by attempting to obtain a general view of the site and the fire damage; this may be achieved at ground level or from an elevated location. Following this, one may examine the materials available, the fuel load, and the condition of the debris at different locations. Surprisingly, the science of fire investigation is not stagnant, and each year, more information to assist investigators in determining the location and cause of a fire by diligent observation of the scene and laboratory study of fire debris is released. This chapter is split into two sections. The first section discusses the general procedures to be used during a fire investigation, and the second section discusses laboratory analysis of ignitable liquid residue analysis.
火灾调查是一项艰巨而富有挑战性的任务。调查人员在火灾现场的基本任务有两个方面:第一,确定火灾的起因;第二,仔细调查起火地点,并试图确定是什么原因引发了在该地点或附近发生的火灾。通常,调查将首先试图获得现场和火灾损害的总体情况;这可以在地面或高处完成。在此之后,人们可以检查可用的材料、燃料负荷和不同地点的碎片状况。令人惊讶的是,火灾调查科学并没有停滞不前,每年都有更多的信息可以帮助调查人员通过对现场的仔细观察和对火灾碎片的实验室研究来确定火灾的位置和原因。本章分为两部分。第一部分讨论了在火灾调查中使用的一般程序,第二部分讨论了可燃液体残留物分析的实验室分析。

Advances in Forensic Sedimentology 法医沉积学进展
Pub Date : 1900-01-01 DOI: 10.4018/978-1-7998-8386-9.ch003

Forensic sedimentology is a relatively recently realized field. Sedimentological methods used to solve cases have evolved as the field has developed, beginning with simple identification of minerals and progressing to the examination of individual grains using highly advanced scanning electron microscopes. More simple methods, such as color analysis, are still used today, but in addition, forensic sedimentologists look at surface textures and grain size distribution. For instance, quartz grains were used in a forensic technique as sediment fingerprint. The particle size distribution is one of the important tests when analysing sediments and soils in geological studies. For forensic work, the particle size distribution of sometimes very small samples requires precise determination using a rapid and reliable method with a high resolution. FRITSCH laser granulometer offers rapid and accurate sizing of particles in the range 0.04–2000 μm for a variety of sample types, including soils, unconsolidated sediments, dusts, powders, and other particulate materials.
法医沉积学是一个相对较新的领域。随着该领域的发展,用于解决案件的沉积学方法也在不断发展,从简单的矿物鉴定开始,发展到使用高度先进的扫描电子显微镜检查单个颗粒。更简单的方法,如颜色分析,至今仍在使用,但除此之外,法医沉积学家还会观察表面纹理和粒度分布。例如,石英颗粒在法医技术中被用作沉积物指纹。粒度分布是地质研究中沉积物和土壤分析的重要指标之一。对于法医工作,有时非常小的样品的粒度分布需要使用快速可靠的高分辨率方法进行精确测定。FRITSCH激光粒度仪在0.04-2000 μm范围内提供快速准确的颗粒尺寸,适用于各种样品类型,包括土壤,未固结沉积物,粉尘,粉末和其他颗粒材料。

This chapter aims to investigate advance and relevance of remote sensing in detecting the increasing transnational terrorist and crimes acts. This work should take into the widest definition of transnational crimes and terrorist activities and the link between. Geopolitics has created a favor climate for the setting of transnational crimes and terrorism at the Tunisian-Libyan borders. A possible future scenario is the fall of a military base with high technology arms in the hand of terrorist groups. Remote would be relevant by monitoring of terrorist mobility and their number evolution, arms quality and quantity within the base and the region, linked illegal activities funding terrorist groups (human trafficking from Africa to Europe, arms trade towards Mali, and smuggling).
本章旨在探讨遥感在侦查日益增多的跨国恐怖主义和犯罪行为方面的进展和相关性。这项工作应考虑到跨国犯罪和恐怖主义活动的最广泛定义以及两者之间的联系。地缘政治为突尼斯-利比亚边境的跨国犯罪和恐怖主义创造了有利的环境。未来可能出现的情况是,一个拥有高科技武器的军事基地落入恐怖组织手中。通过监测恐怖分子的流动及其数量演变、基地和区域内武器的质量和数量、资助恐怖主义集团的非法活动(从非洲到欧洲的人口贩运、向马里的武器贸易和走私),远程将是相关的。

Financial sectors are lucrative cyber-attack targets because of their immediate financial gain. As a result, financial institutions face challenges in developing systems that can automatically identify security breaches and separate fraudulent transactions from legitimate transactions. Today, organizations widely use machine learning techniques to identify any fraudulent behavior in customers' transactions. However, machine learning techniques are often challenging because of financial institutions' confidentiality policy, leading to not sharing the customer transaction data. This chapter discusses some crucial challenges of handling cybersecurity and fraud in the financial industry and building machine learning-based models to address those challenges. The authors utilize an open-source e-commerce transaction dataset to illustrate the forensic processes by creating a machine learning model to classify fraudulent transactions. Overall, the chapter focuses on how the machine learning models can help detect and prevent fraudulent activities in the financial sector in the age of cybersecurity.

Traditionally, forensic geophysics involves the study, search, localization, and mapping of buried objects or elements within soil, buildings, or water using geophysics tools for legal purposes. Recently, with the evolution of environmental crimes, forensic geophysics gave special care to detection, location, and quantification of polluting products. New techniques including the magnetic susceptibility have emerged to investigate this type of crimes. After discussing the state of the art of forensic geophysics, this chapter proposed the magnetic susceptibility as an efficient tool of environmental crimes detection. A case study of pollution detection was proposed from Tunisia. Being a fast and cheap technique, magnetic surveys represent a real promise for environmental forensic geophysics.

In this chapter, an AI (artificial intelligence) solution for LPR (license plate recognition) on moving vehicles is proposed. The license plates in images captured with cameras on moving vehicles have unpredictable distortion and various illumination which make traditional machine vision algorithms unable to recognize the numbers correctly. Therefore, deep learning is leveraged to recognize license plate in such challenging conditions for better recognition accuracy. Additionally, lightweight neural networks are chosen since the power supply of scooter is quite limited. A two-stage method is presented to recognize license plate. First, the license plates in captured images are detected using CNN (convolutional neural network) model and the rotation of the detected license plates are corrected. Subsequently, the characters are recognized as upper-case format (A-Z) and digits (0-9) with second CNN model. Experimental results show that the system achieves 95.7% precision and 95% recall at high speed during the daytime.
在本章中,提出了一种基于移动车辆车牌识别的人工智能解决方案。移动车辆上的摄像头拍摄的车牌图像具有不可预测的失真和不同的光照,这使得传统的机器视觉算法无法正确识别车牌数字。因此,在这种具有挑战性的条件下,利用深度学习来识别车牌,以获得更好的识别精度。此外,由于滑板车的电力供应相当有限,因此选择了轻量级神经网络。提出了一种两阶段车牌识别方法。首先,利用CNN(卷积神经网络)模型对采集图像中的车牌进行检测,并对检测到的车牌旋转进行校正;随后,使用第二个CNN模型将字符识别为大写格式(A-Z)和数字(0-9)。实验结果表明,该系统在白天高速运行时准确率达到95.7%,查全率达到95%。

Image-related crimes cause the urgent demand for tracing the origin of digital images. The breakthrough is a passive detection method via photo response non-uniformity (PRNU) analysis proposed by Lukáš et al. Recently, digital images are often shot with handheld devices (such as smartphones) and transmitted using social media (such as LINE). Most of the images are distorted (such as compressed and resized) during transmission. Previous studies are less focused on the impact of transmission compression through social networks. Thirty-one different Apple mobile phones were used to capture digital images in the experiment. Images were uploaded to the photo album via LINE software and then downloaded. The modified signed peak correlation energy (MSPCE) statistics is used to evaluate the correlation between the PRNU values of the disputed images and the pattern noise of the experimental devices. Experimental results show that the PRNU analysis method can effectively trace the source of the shot device using the distorted images which are compressed and resized during the transmission in LINE.
图像犯罪引发了对数字图像溯源的迫切需求。突破口是Lukáš等人提出的通过光响应非均匀性(PRNU)分析的被动检测方法。最近,数码图像通常是用手持设备(如智能手机)拍摄的,并通过社交媒体(如LINE)传播。在传输过程中,大多数图像都是扭曲的(如压缩和调整大小)。以往的研究较少关注通过社交网络传输压缩的影响。在实验中,31款不同的苹果手机被用来捕捉数字图像。照片通过LINE软件上传到相册,然后下载。利用改进的符号峰值相关能(MSPCE)统计量来评估争议图像的PRNU值与实验设备的模式噪声之间的相关性。实验结果表明,PRNU分析方法可以有效地利用在LINE传输过程中压缩和调整大小的畸变图像来跟踪射击装置的源。
