The use of 3D imaging device is proving to be beneficial to crime scene investigators (CSI) as an additional toolkit since it can obtain details of such impression. Footwear impression recovery in crime scene is considered to have a critical role in the investigations to narrow down the number of suspects or refute or corroborate information (Gamage et al., 2013). Three dimension foot ware impressions casting is seen to be a long standing standard where, it results to the generation of three dimensional footprints. This is progressively being replaced by a three dimensional scanning that is a less invasive method. In the study proposed, an alternative method that entails a 3D laser scanning of footwear impression evidence with the use of a FARO "Freestyle" 3D Scanner will be present, and it will be based on the multi-view stereo where, an accurate three dimensional model can be generated. The results on the reconstructed three dimensional models will be evaluated and then compared with other results obtained by three dimensional scanning. Also, the drawbacks and the advantages of this method will be explored over other methods that exist. Freestyle hand held scanner was recently released by FARO, and this is considered as a step up in structured light technology because it includes two cameras infrared in nature which are used in creating a stereo pair of images

...? Full Paper Introduction Discussing computer forensics in the context of law enforcement agencies or in corporate security, itwill lead to a conclusion of a subject that covers the utilization of computers to catalog physical evidence that is analyzed in other forensics techniques including biometric identification, analyzing DNA and dental evidence. Current technological trends have revolutionized the methods of storing data along with different advanced access mechanisms. These systems facilitate law enforcement agencies by providing instant access to these characteristics. Although, computer forensics also facilitates in investigation of crimes within themselves in order to gather evidence associated with criminal activities... that...

Distributed network access (DNA) is a new methodology for recovering files that are password protected. The methodology of DNA makes it proficient and effective because DNA uses the computing capability of all the active nodes on the network, in order to break or decrypt the password (Decryption & password cracking software, n.d). The DNA provides best results on a centralized architecture, as it will integrates itself by a DNA client that is installed and located on every workstation on the network. The primary goal is to distribute the dissimilar and criteria based key...

...? Significance of Forensic Evidence Introduction Forensic evidence is anything that has been collected in a scene of crime that gives the description of the way the crime was done. This can also confirm the description stories that are given by the eyewitnesses. Another definition of forensic evidence can be evidence that can be used by a law court, especially the evidence that has been obtained via scientific methods like DNA tests, blood tests and ballistics (James & Nordby, 2009). Forensic evidence has, therefore, assisted the law sector through shaping the justice in...

The major application of this 3D technology was first applied in the textile field that was highly related to the military industry (International Conference on Systems, Computing Sciences and Software Engineering, Sobh, and Elleithy, 2006; p. 153). The body scanning has become a successful tool in military especially in facilitating the manufacturing of the military uniforms. It is often used for selection since it provides proper sizes of the uniforms for the entire staff (Aldrich, 2001; p. 34... ). The...

Forensic Evidence

...? Forensic Evidence Essay First Forensic Evidence Essay Part This crime scene record is lacking in a lot of very important information. To start with, it has no indication of the time when this crime scene inspection was done1. It has a date but that does not make it very clear at all when the suspected incident, which it reports as burglary and assault was reported and when the subsequent crimes scene inspection took place. It makes no reference to the person who reported the crime. Was it phoned in? Was it something that police on patrol or some other duty came upon? Was it reported at the police station and thus police officers we sent to inspect? How was the crime...

Forensic Science: DNA Evidence

...Payton Quintina Payton Forensic Science: DNA Evidence Like most of other branches of science, forensic science has been rapidly developing during the last century. "DNA analysis promises to be the most important tool for human identification since Francis Galton developed the use of fingerprints for that purpose". (Committee on DNA Forensic Science, 1996). DNA identification is one of the most valuable instruments for the contemporary criminologists. This type of analysis provides a very high probability of tracing the criminal in case at least some genetic material that belongs to him is present on the crime scene. DNA identification may allow sparing the world from...

Using Computed Tomography (CT) Scanning Technique in Forensic Entomology

...in the carrion, analysis of DNA and analysis of results. The EAFE recommends that investigators should follow those procedural standards to ensure the validity of the results, once those are presented in legal analysis. Conclusively, through the related literatures studied in this paper, this research asserts that the CT scanning technique is reliable enough in providing scientific and actual data on death-related cases, particularly in the medico-legal analysis. The said method may serve as a reliable tool in gathering medico-legal evidences that could pinpoint the cause, place, time and manner of death. References Amendt, J., Campobasso, C.
