Which process is critical after creating digital evidence images to ensure they are not tampered with?

Creating verification hashes is a critical step after imaging digital evidence because it provides a reliable way to verify the integrity of the data. A hash function generates a unique identifier for the data; any alteration, however minor, will produce a different hash value. By generating and storing a hash for each image, forensic examiners can ensure that the image remains unchanged throughout the investigation process. This verification process is essential for maintaining the chain of custody and upholding the evidential value of the data in court.

Other processes, such as encrypting the images, documenting the imaging process, or storing images on a cloud server, are important but do not directly address the immediate need for ensuring the integrity of the digital evidence through verification. Encrypting images can enhance security but does not inherently verify that the evidence is unaltered. Documenting the imaging process is critical for transparency and reproducibility but does not prevent tampering. Storing images on a cloud server can raise concerns related to security and access, which could potentially risk the integrity of the data if not properly managed.
