What is the purpose of conducting a chain of custody in digital forensics?

The purpose of conducting a chain of custody in digital forensics is primarily to document who handled evidence and when. This meticulous documentation is crucial for establishing the integrity and authenticity of the evidence collected during an investigation. It allows forensic examiners to track the evidence from the moment it is collected through to its presentation in court, ensuring that it has not been altered, tampered with, or mishandled in any way.

A well-maintained chain of custody helps to bolster the credibility of the evidence and the findings derived from it; if the evidence can be shown to have been consistently secured and managed, it increases the likelihood that it will be accepted in legal proceedings. This process is foundational in maintaining the trust of the court and the parties involved in the investigation, as it guarantees that the evidence presented is reliable and has been preserved according to established protocols.
