Processing Fingerprints

“A Simplified Guide to Fingerprint Analysis” lists three types of prints that can be lifted at a crime scene (2013). They are as follows: (Note: all information in this section comes from this article). Soft surface prints. These 3-dimensional plastic prints are found in soap, wax, wet paint and fresh chalk. Hard surface prints. The prints fall under two categories.

Patent Prints (Visible)

Found on smooth, rough, porous (paper, cloth, wood), and nonporous (metal, glass, plastic) surfaces. Can be found in blood, dirt, paint and ink. Collecting patent prints is done by high-resolution photography. To improve the quality of the ...

The fingerprint processing and the DNA processing can be done simultaneously. In fact, the fingerprint collection is beneficial for the processing of DNA evidence, but there is one way that the fingerprint processing can actually impact the collection of DNA evidence, and that is through contamination of DNA due to the fingerprint reagents. According to different researches different samples of blood, fingerprints have been analyzed, and all the possible fingerprint reagents are ranging from Cyanoacrylate to fingerprinting powders to Ninhydrin to reach the profile evidence of DNA of the blood were tested to check how the fingerprint reagents can ...

A DNA profile is generated with the help of the DNA is that is left behind by the skin cells. This is known as the Touch DNA. Even though the samples that are used in this case are very small but the Touch DNA can be retrieved with the help of a technique that is launched recently and is known as the Polymerase Chain Reaction (PCR) which will take small samples of the DNA and make similar millions of copies within just two to three days . As the collection of fingerprints is a difficult task, and there is a ...

Question and Answer- Criminal Justice

Question and Answer- Criminal Justice Q. 1 The main similarity between mens rea and actus reus regarding their roles is that both elements are ways through the criminal law ensures that only guilty actions or conduct and minds or intention can secure the safe legal conviction of accused persons. Moreover, they both play the role of making the role of the prosecution and defense easier when proving the commission of a crime. The difference is that while mens rea plays the role of helping the court know the accused’s intent at the material time, actus reus plays the ...

Payment methods and technologies have shifted a great deal over the years. Gone are the days where cash and check transactions make up the bulk of the give and take that occurs when people engage in commerce, travel and otherwise spend their money. Credit and debit cards have ruled the roost for a while but some new contenders are starting to emerge. The first major alternative to the conventional credit cards and other more traditional methods was PayPal (PayPal, 2017). However, smartphone-enabled technologies such as Apple Pay, Samsung Pay and Android Pay are starting to dominate the commerce and ...

Latent prints can be defined as the pretense of individual’s ridged skin. They are generally known as friction ridges or fingerprints. These impressions are regularly imperceptible to the exposed eye despite the fact that they are surrounding us and each one of us accidently leaves them everywhere. At the point when an investigator is dealing with a crime, other than taking a gander at the physical proof, one of the main things they do is check for fingerprints. This is an exceptionally sensitive process on the grounds that relying upon the surface a latent print can without much ...

A porous item is a surface that contains openings that allow for the absorption of liquids to go through the material. One of the typical examples of porous materials is raw wood as it can absorb liquids or fingerprints oils especially if it is not varnished. Chemical development can be done through fingerprint processing of natural wood that is from a physical developer. Fingerprints can be developed through chemical processes of a silver based reagents that prints are produced, and they become gray colored (Trozzi 2001). In a crime scene, you can get wood outdoors, and this can also ...

Fingerprint analysis is the oldest and common form of forensic evidence and unique of each individual. There are two types of finger prints –patent and latent. Patent fingerprints are easily visible to the naked eye and are caused by inks, blood, oil or paint ("A Simplified Guide To Fingerprint Analysis", 2017). Latent ones are not visible to the naked eye and are caused by skin secretions like oil and sweat (Daluz, n.d.). There are various ways of experimenting the latent fingerprints depending on the surface, material, temperature and chemicals. Here we will study the effect of different temperatures (hot ...

Permanence and Uniqueness are two principles used in understanding the embryology and physiological development of friction ridge skin. The uniqueness and permanence of friction ridge skin have been applied as one of the fundamental factor used in fingerprint identification in forensic science. Fingerprint identification, analysis and comparison play a significant role in forensic science for solving criminal cases. It is imperative to note that friction ridge skin possesses unique attributes that persevere from before birth until decay after death (Edelmann & Denton, 2007). These two principles of unique attributes and their persistence from before birth until decomposition after death are ...

Fingerprints identification has a very long history in the criminal justice department. It is the perfect way to track and pick out a criminal from the suspects. This makes it raise a lot of questions of what makes it the best way to identify a criminal. The question leads to the two premises of fingerprint identification. Fingerprint identification has two major premises; uniqueness and persistence (permanence). Every person has a unique fingerprint that is different from everyone else. It is not easy, almost impossible, to have to share the same fingerprint patterns. Uniqueness premise gives fingerprint identification the most ...

Automated Fingerprint Identification System (AFIS) refers to a computerized system used to store fingerprint images. Typically, investigators feed new print images into AFIS to identify the best matches. Accordingly, the identification process allows investigators to narrow their search parameters. Usually, AFIS technicians perform the final analyses of retrieved images to maintain accuracy. Prior to the computerization of such systems, the process of comparing fingerprint images was tedious and sometimes inaccurate. The development of AFIS, however, allowed technicians to perform comparisons within minutes and achieve a relatively higher accuracy of image identification.

Set of Requirements for the Network Solution

For this case, the attorneys will need to access the company network both from within their offices and when they are on site. The set of requirements for this will be the provision of a corporate WAN network that will only allow the authorized personnel to access it within the office. The second requirement for the mobile network is the provision of a Virtual Private Network that will allow the mobile users to access the company resources outside their offices while still maintaining security of the firm’s information. The access to the network will need to be secured ...

Abstract

Forensic Science has long found important application in a criminal investigation, and its correct usage will enhance its effectiveness in crime detection. The use of forensic science in intelligence has allowed the possibility of crime scene reconstruction, identification of a suspect and the elements therein. Law enforcement has gone a notch higher in crime investigation in the sense that scouring for limited evidence at crime scenes has been made possible long after the perfect crime has taken place. The sole purpose of finding the obscure evidence is to have the criminals responsible brought to book and as a result, ...

In criminal justice, resource availability in court systems is a very vital element in dealing with certain issues as well as cases. Without availability of resources within court systems, it becomes quite difficult to impossible to conduct research in order to find out the relevant information needed while investigating cases as well as deciding upon them. In order for the court systems to function well in terms of dealing with the cases and issues presented before them, the necessary research should be available in order to conduct this process and be successful (Grant, 2016). There are different resources that ...

The “exclusionary rule” is one of the most important elements of United States criminal procedure law, but it is not found in the Constitution. Indeed, the exclusionary rule is a court created procedure that allows a judge to declare inadmissible any testimony or evidence presented at trial that was result of or otherwise obtained in violation of the Bill of Rights’ Fourth, Fifth, or Sixth Amendments. In other words, while the basis of the exclusionary rule is the Constitution, it is not a constitutional right. Rather the exclusionary rule was created as a means for the court to prevent ...

Crime scene investigation is an important area of the criminal justice field. The CSI groups are expected to find and collect evidence at crime scenes. They are to follow the guidelines of collecting the evidence and packaging it properly. The proper packaging is to ensure that the evidence stays fresh and does not get contaminated. They then ensure that the evidence is delivered at the proper analyzation and examination teams to further review the evidence. Once the evidence is reviewed and properly understood then the investigators continue with this information to obtain a warrant, capture a suspect, or use ...

The CSI effect is intrigued by many crime scene shows on television. These shows are based on what real crime scenes and investigators go through. They have a similar process to accessing a crime scene and locating evidence in the crime. They portray the shows to have a real life effect on the real cases and situations that investigators deal with. The increase in different versions of these shows is all over the networks. People enjoy watching the real life crime and the drama that it details. What the shows are simulating is that the crimes can be processed, ...

The use of biometric evidence in executing criminal justice has gained reputation throughout the world as a result of rapid advancement in technology. In essence, biometric recognition entails the use of biometric equipment to recognize individuals through their biological characteristics (Sanders et al., 2010). Bio information of a person is captured and analyzed for use in identification. Some examples of bio information include fingerprint and signatures. A biometric evidence is the most popular and convincing method of confirming the identity of a person (Reedman, 2015). The criminal justice system uses different biometric characteristics to identify criminals depending on the ...

Abstract

In the recent times, scientists in the discipline of artificial intelligence are confused which approach closely imitates the structure of a human brain. The best two approaches are bottom-up, or the top-down, and they comprise of both their advantages and disadvantages. The top-down approach has the capability to perform high-level tasks since it is programmed (Russell et.al 27). On the contrary, the bottom-up approach is capable of modeling the lower-level human functions such as motor control, image recognition, and learning capabilities. Each method operates perfectly where the other method is imperfect. Therefore, to establish the advantages and disadvantages of ...
