This paper aims to study the Countermeasures of big data security management in the prevention and control of computer network crime in the absence of relevant legislation and judicial practice. Starting from the concepts and definitions of computer crime and network crime, this paper puts forward the comparison matrix, investigation and statistics method and characteristic measure of computer crime. Through the methods of crime scene investigation, network investigation and network tracking, this paper studies the big data security management countermeasures in the prevention and control of computer network crime from the perspective of criminology. The experimental results show that the phenomenon of low age is serious, and the number of Teenagers Participating in network crime is on the rise. In all kinds of cases, criminals under the age of 35 account for more than 50%.

The long practice of fingerprint science is accompanied by confusing thoughts affecting the interpretation of the fingerprint evidence recovered from a crime scene, and, consequently, prosecutors and judges’ decisions as well. However, despite the tremendous scientific and technological developments relating to fingerprint enhancement, processing, and usage, which clarify precise facts regarding the influence of deposition circumstances, substrate, light, air, temperature, and time factors on fingerprint secretions, misconceptions about fingerprints are still widespread within the law enforcement and judicial system. This problem prevents the proper usage of fingerprints in fighting crimes and supporting the justice system by strong physical evidence. This study aims to highlight some scientific facts about fingerprints as well as a new approach and reconceptualization of fingermarks as a tool for crime scene investigation and training. The article discusses twenty-four myths about fingerprints – part 1 covers ten of them and part 2 discusses the other fourteen.

Forensic photography, also referred to as crime scene photography, is an activity that records the initial appearance of the crime scene and physical evidence in order to provide a permanent record for the court. Nowadays, we cannot imagine a crime scene investigation without photographic evidence. Crime or accident scene photographs can often be reanalyzed in cold cases or when the images need to be enlarged to show critical details. Fractals are rough or fragmented geometric shapes that can be subdivided into parts, each of which is a reduced copy of the whole. Fractal dimension (FD) is an important fractal geometry feature. There are many applications of fractals in various forensic fields, including image processing, image analysis, texture segmentation, shape classification, and identifying the image features such as roughness and smoothness of an image. Fractal analysis is applicable in forensic archeology and paleontology, as well. The damaged image can be reviewed, analyzed, and reconstructed by fractal nature analysis.

This paper presents the recreation of crime scenes through Virtual Reality for crime investigation and evidence storage. 3D image capturing and processing techniques are used to render fully-immersive Virtual Reality environment for investigators to work with. Cloud database and Blockchain technology for evidence storage are explained. The different levels of views on such virtual crime scenes and evidence storage are also expounded.

Evidence is an important concept in order to reveal whether a crime really exists or not and integrate it with all its elements. There are numerous methods of crime scene investigation in forensic cases. During the judgment phase, the most important factor that will help understand and decide the manner in which the incident took place is the evidence that will provide proof with regard to the incident. Therefore, evidence helps prosecutors and judges correctly understand and establish the relationship between the crime and the criminals and prove the committed crime and ensure correct, fair and rapid execution of the trial with the aim of reaching the material truth. Evidence obtained in the crime scene provides information with regard to the manner in which the crime was committed, the time of the crime, thebehaviour of the perpetrator, the suspect, the victim and the crime scene ensuring the establishment of the relationship between them. On the other hand, with the digital systems gaining more placein the life of the society, the crime scene has shifted from a physical environment to a digital one. Consequently, new types of crimes are committed digitally and as a result, the concept of digital evidence has arisen. There are no specific laws on the collection of digital evidence under Kosovo's legislation. On the other hand, there are legal regulations regarding digital evidence in exemplary countries such as Turkey. This study will comprise of the methods of gathering evidence in forensic cases and the comparison of the legal legislation on digital evidence in Kosovo and Turkey.   Received: 5 June 2021 / Accepted: 15 July 2021 / Published: 5 September 2021

A valuable aspect during crime scene investigation is the digital documentation of the scene. Traditional means of documentation include photography and in situ measurements from experts for further analysis. Although 3D reconstruction of pertinent scenes has already been explored as a complementary tool in investigation pipelines, such technology is considered unfamiliar and not yet widely adopted. This is explained by the expensive and specialised digitisation equipment that is available so far. However, the emergence of high-precision but low-cost devices capable of scanning scenes or objects in 3D has been proven as a reliable alternative to their counterparts. This paper summarises and analyses the state-of-the-art technologies in scene documentation using 3D digitisation and assesses the usefulness in typical police-related situations and the forensics domain in general. We present the methodology for acquiring data for 3D reconstruction of various types of scenes. Emphasis is placed on the applicability of each technique in a wide range of situations, ranging in type and size. The application of each reconstruction method is considered in this context and compared with respect to additional constraints, such as time availability and simplicity of operation of the corresponding scanning modality. To further support our findings, we release a multi-modal dataset obtained from a hypothetical indoor crime scene to the public.

We conducted a content analysis of the first two and last two seasons of the popular crime drama Crime Scene Investigation ( CSI), to determine the extent to which depictions of the intersection of substance use and violence were consistent with research. Using the lens of system justification theory, we find that CSI focuses on aspects of crime that preserve the status quo, specifically it overemphasizes the negative impact of illicit substances as opposed to legal substances (such as alcohol), and it emphasizes the psychopharmacological role of drugs in violent crime compared to systemic violence related to the illegality of drug markets, even though research demonstrates that systemic violence makes up a large proportion of substance-related homicides. Despite significant changes in drug policy that occurred during the time that CSI was on the air, we find these portrayals are largely unchanged between episodes that were broadcast between 2000–2002 versus those that aired 2014–2015.
