What is the importance of preserving the original evidence in digital forensics?

Preserving the original evidence in digital forensics is crucial for maintaining its authenticity and integrity, which are fundamental for court admissibility. When evidence is collected from a digital device, it contains vital information that must remain unchanged to be considered reliable in legal proceedings. Any alteration or manipulation of the original data can lead to challenges regarding its legitimacy, potentially disqualifying it from being used in court.

Maintaining the integrity of the evidence ensures that it accurately reflects what was found during the investigation, supporting the trustworthiness of the findings and the conclusions drawn from them. Therefore, preserving the original evidence allows forensic experts to provide robust testimony about the evidence's source and condition, which is essential for the legal system's functionality and fairness.
