Computer Forensics Expert Witnesses

Start Computer Forensics Expert Search

Computer forensics expert witness candidates typically have extensive experience in computer science. A computer forensics expert witness needs to not only have substantive expertise, but must also possess the ability to explain digital evidence and technology to jurors. In a high-profile case, or litigation involving a significant financial stake, the legal team may request a technologist with prior expert witness testimony experience. A branch of digital forensic science, computer forensics work is performed to obtain digital information. Computer forensics can be used to incriminate individuals in fraud cases, and can also assist in catching criminals who don’t think they left an imprint when committing certain crimes. Computer forensic evidence can be used to trace hacking, espionage and even bank fraud. The discipline involves similar techniques used in data recovery, but are specifically designed to create a legal audit trail.

Matters requiring computer forensics expert witness services can involve intellectual property litigation, such as software copyright, or trade secret disputes. A criminal investigation involving fraud or electronic discovery data can also call for a computer forensic investigation. Litigation support by a computer forensics expert could include analysis, expert report preparation, expert opinion, depositions, and expert testimony in the courtroom. Cahn Litigation Services is frequently called upon by attorney clients to locate experts that can support matters requiring computer forensic discovery. The firm has the experience required to turn a search around quickly and provide qualified candidates that mirror the specifications set by the law firm.
