Executive Overview Digital forensics investigations live or die on two pillars: the integrity of the evidence and the clarity of its custody history. A single gap in the chain — one unlogged file access, one unverified hash — is all the defense needs to cast reasonable doubt. Digital_V3 was engineered to eliminate those gaps entirely. It is a unified, forensicgrade evidence management platform that ingests raw seized files and immediately wraps them in a cryptographic and procedural framework that is — by design — impossible to quietly undo.
