What is a forensic image Why is it used?
Creating and backing up a forensic image helps prevent loss of data due to original drive failures. The loss of data as evidence can be detrimental to legal cases. Forensic imaging can also prevent the loss of critical files in general.
What is a forensic image?
A forensic image is a special type of copy of the original evidence, it contains all of the data found in the original, but that data is encapsulated in a forensic file format which makes it tamper-proof.

What are the six phases of the forensic investigation process?
This model was the base fundament of further enhancement since it was very consistent and standardized, the phases namely: Identification, Preservation, Collection, Examination, Analysis and Presentation (then a pseudo additional step: Decision). Each phase consists of some candidate techniques or methods.
What are the disadvantages of forensic science?
☛ DNA analysis of a person is believed to be against human ethics, as it reveals private information about an individual. ☛ Equipment used in forensics is expensive. ☛ Scientific analysis consumes lot of time because of which the verdict is delayed. ☛ It requires precise and accurate analysis.
What is digital imaging in forensics?
Digital Forensic Imaging is defined as the processes and tools used in copying a physical storage device for conducting investigations and gathering evidence. The image is an identical copy of all the drive structures and contents.
What are the dangers of being a forensic scientist?
While some forensic technicians work primarily in the lab, others routinely visit crime scenes to collect and document evidence. Because many crime scenes are outdoors, forensic technicians may be exposed to hazardous weather conditions such as extreme heat or cold, snow, rain, or even damaging winds.
Why do we need forensics?
Role of Forensic Science in Criminal Investigations Forensic science is that piece without which the puzzle of a criminal investigation is incomplete. Without the application of forensic science, criminals can never be convicted unless an eyewitness is present.
What is the first rule of digital forensics?
The first rule of digital forensics is to preserve the original evidence. During the analysis phase, the digital forensics analyst or computer hacking forensics investigator (CHFI) recovers evidence material using a variety of different tools and strategies.
Is Computer Forensics a good career?
Is Computer Forensics a good career? There is a high demand for expertise in computer forensics. Following the increasing reliance on the internet and computer technologies, computer forensics has become a significant part of business and law and a very lucrative career path.
What is the main focus of forensic science?
The topic. Forensic science assists in the investigation of crimes by examining physical evidence, and applying the results of these scientific examinations to courts of law. The results of examinations can determine what happened at the scene of a crime and who was there.
How has technology improved forensic science?
Image enhancement technologies are enabling investigators to read clues such as fingerprints, footprints and bite marks. And computer science is enabling police to collect evidence from e-mail and other digital files. Recent advances in forensic technology are built on centuries of progress in the field, Dr. Lee says.
What is photo forensics?
Photo Forensics as a term will typically refer either to the profession dedicated to authenticating digital images to determine authenticity, or, it may refer to the capability of digital forensics software to find and identify photos.
Why is digital forensics important?
Computer forensics is also important because it can save your organization money. From a technical standpoint, the main goal of computer forensics is to identify, collect, preserve, and analyze data in a way that preserves the integrity of the evidence collected so it can be used effectively in a legal case.
How does forensic science impact criminal justice and court systems?
Forensic science is a critical element of the criminal justice system. Forensic scientists examine and analyze evidence from crime scenes and elsewhere to develop objective findings that can assist in the investigation and prosecution of perpetrators of crime or absolve an innocent person from suspicion.
What are the four roles of evidence in a criminal investigation?

How has forensic science changed the world of criminal justice?
Undoubtedly, the aspect of forensic science that has had the greatest impact on society is that of DNA fingerprinting. DNA evidence has led to more convictions than ever, especially in cases of sexual assault, where bodily fluids present at the crime scene or on the victim can be matched with a suspect’s DNA.
