A computer forensic expert is a witness who testifies in court about data collected from computer systems. They work with attorneys to explain technical issues related to computer forensics and can work on civil or criminal cases. Their testimony can be crucial in establishing the legality and reliability of evidence obtained from computers.
A computer forensic expert is a person who works with attorneys as a witness in cases involving computer information. He or she may be someone who also works in computer forensics and may testify about data she recovered directly, or the expert may simply be representing others who were part of the job. This type of witness will usually be an expert in the fields of computers, information technology, or computer forensics and should be able to effectively communicate concepts related to those topics to others. A computer forensic expert can work on civil or criminal cases.
Since a computer forensic expert will typically testify in court about data collected by computers, he or she will usually be an expert in some field of computer science. The exact nature of the work can vary, from professors teaching computer science in universities to computer forensic operators testifying about their work. Computer forensics is the field of study and research that uses information or data that can be obtained from computer systems, both hardware and software, to aid in criminal or civil investigations.
A computer forensics expert will typically work with an attorney to provide testimony in a court hearing about some aspect of computer forensics. This is usually done to help a judge or jury understand fairly complex technical issues and language related to the computer forensics work that has been done on a case. Such testimony can be especially important if computer forensics has been used to gather information crucial to a case, and proper defense of this information can impact how it is received in the courtroom. A forensic computer expert may, for example, explain how information was retrieved from a program found on a defendant’s computer to support admitting that information as evidence in a trial.
Due to the nature of computer forensics work, a computer forensics expert may work on civil or criminal lawsuits. For civil trials, it would likely work on divorce hearings, bankruptcy proceedings, and lawsuits where data on a computer can provide culpability or establish malpractice. Computer forensics has also been used to track suspects in criminal investigations. When this type of investigation goes to trial, a forensic computer expert may need to testify to explain how the information was obtained and demonstrate that the process by which it led to a defendant was legal and reliable.
