Why does chain of custody matter for digital material?

Because electronic evidence is trivially alterable, its weight depends on a demonstrable record of who held it, when, and what was done to it. A break in that record is the most common reason otherwise strong material is discounted.

Is a screenshot admissible evidence?

A screenshot is a starting point, not a preserved artefact. Where possible the underlying source is captured with hashes, timestamps and contextual metadata so the material can be authenticated independently of the screenshot itself.

Can deleted material always be recovered?

No. Recoverability depends on the platform, storage medium, retention policy and elapsed time. Where material cannot be recovered, that limitation is documented rather than inferred over.

Digital Forensics

Digital forensics governs how electronic material is captured, preserved and examined so that findings survive challenge. The controlling question is not what can be recovered from a device or account, but whether the process can be demonstrated to a court.

The resources indexed here cover acquisition and hashing, metadata extraction and interpretation, account and communication artefacts, and the reporting format used when findings are relied upon in proceedings.
