Since discovery of an underlying organisational structure from crime data leads the investigation to terrorist cells or organised crime groups, detecting covert networks are important to crime investigation. As shown in application of Offender Group Detection Model (OGDM), which is developed and tested on a theft network in Bursa, Turkey, use of effective data mining methods can reveal offender...

Computer forensics has the main objective to find digital evidences of crimes. One of the most researched digital crimes is the sexual abuse of children, including the production, sharing and possession of child pornographic files. Aiming to quickly detect files of child pornography at crime scenes, the NuDetective Forensic Tool was previously developed and it uses techniques like nudity detect...

The Home Office Police Research Group (PRG) was formed in 1992 to carry out and manage research relevant to the work of the police service. The terms of reference for the Group include the requirement to identify and disseminate good policing practice. The Crime Detection and Prevention Series follows on from the Crime Prevention Unit papers, a series which has been published by the Home Office...

Digital forensic is part of forensic science that unconditionally covers cyber crimes. In a cyber crime digital forensic evidence examination requires a special process and techniques in examination of cyber crime in crime scene and examination of evidence are accepted in law enforcement. Cyber crime involves log data, transactional data is occurs which tends to plenty of data for storage and a...

We present a new approach for detecting related crime series, by unsupervised learning of the latent feature embeddings from narratives of crime record via the Gaussian-Bernoulli Restricted Boltzmann Machines (RBM). This is a drastically different approach from prior work on crime analysis, which typically considers only time and location and at most category information. After the embedding, r...

Previous research on the Concealed Information Test indicates that knowledge of the critical information of a given event is sufficient for the elicitation of strong physiological reactions, thus facilitating detection by the test. Other factors that affect the test's efficacy are deceptive verbal responses to the test's questions and motivation of guilty examinees to avoid detection. In the pr...

Improvements in detection limits/sensitivity and lower sample consumption are potential benefits of reducing PCR reaction volumes used in forensic DNA typing of crime scene samples. This premise was studied first with experimental mixtures and a nine-loci megaplex, which demonstrated stochiometric amplification and accurate detection. Next, adjudicated casework samples were subjected to amplifi...
