victim identification database – a specialized, secure system used by law enforcement and agencies (like Interpol, NCA) to store, analyze, and compare digital evidence (images, videos) from crimes, especially child sexual abuse material (CSAM), using advanced software to find patterns, link cases, identify victims, and locate perpetrators for rescue and prosecution. These databases help investigators by grouping related content (series) and using techniques like image matching (hash values) to recognize victims across different files and jurisdictions, protecting children and bringing offenders to justice.
