Forensic analysis refers to a detailed investigation to detect and document the course, causes, criminals, and consequences of a security incident or violation of rules of the organization or state laws. Five common types of forensic analysis are computer, bloodstain, deoxyribonucleic acid (DNA), handwriting, and statement analysis. Forensic Data Analysis (FDA) is a branch of digital forensics that examines structured data with concerning incidents of financial crime. Currently, DNA forensic is experiencing heavy research and development with substantial new product introduction. The main use of forensic science is to investigate crimes such as theft, murder, or fraud. Forensic scientists also investigate accidents such as plane crashes to find out if they were accidental or a result of foul play.
Forensic analysis, also called forensic chemistry, is the application of chemistry to forensic and legal laws, primarily on the forensic side-on the legal side. Forensic analysis relies on the study and conclusions of any physical evidence that is relevant to a case being handled by a forensic attorney or police officer. These include such things as drug testing, hair analysis, bite marks analysis, blood tests, etc. Forensic evidence generally must be collected and analyzed using methods that are consistent with forensic chemistry. Examples of such methods include the use of gas chromatography/mass spectrometry. Forensic scientists and investigators use forensic analysis to determine the presence and or absence of a criminal offense.
This application includes the examination of physical evidence, clothing or personal effects, and any DNA samples taken from the criminal. In recent years, the process of forensic analysis has gained so much popularity due to the advancements made in scientific research and technology. The science of forensics has made great strides in the past decade, especially due to the work of many dedicated, well-trained and highly skilled criminalists, and police officers. In the United States, there are strict regulations for the consumption of controlled substances. For instance, the Controlled Substances Act controls the manufacturing, distribution, and dispensing of controlled substances across the United States.
Forensic analysis and the application of forensic tools are widely used in the law enforcement investigations. Although this technology was once reserved for large criminal cases only, thanks to the work of countless dedicated scientists and law enforcement professionals, it can now be applied to just about any type of investigation. The most common application of forensic tools falls under the category of physical matching fingerprints. This type of analysis requires the use of specialized software programs such as the National Bureau of Standards database and the FBI fingerprint instrument. These databases contain thousands of different fingerprints of people and help match them to an unknown fingerprint found in a number of places across the country.
The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. Another application of forensic analysis comes in the form of digital forensics software. Many digital forensics experts use this type of software to perform their job, and in most cases, the software works just like a forensics expert would. Experts can determine the digital fingerprint of an unknown user by using a known image, or by using image recognition technology to recognize patterns and anomalies in the system files or in the hard drive. Some other advanced digital forensics applications are also available for digital forensics experts, such as digital image extraction and image retrieval, fingerprint identification, and the analysis of digital media and databases.
