Forensic Capture

Definition

Common questions

Why is a screenshot alone considered weak evidence?+

A screenshot can be edited, cropped or staged with no independent way to verify when it was taken or what the page actually looked like at that moment, so opposing counsel can challenge its authenticity without a supporting technical record.

What does the page hash actually prove?+

The hash is a fixed-length value calculated from the captured page content. If the content changes even slightly, the hash changes too, so matching hashes on re-verification show the captured copy has not been altered since collection.
