I suspect child abuse; is CCTV forensics at a daycare center possible?

If it is a situation where child abuse is suspected within the daycare center, the most important measure is securing CCTV footage.

However, from 2025, the CCTV viewing system has been strengthened.

Previously, it was possible to view the CCTV immediately just by submitting a doctor's written opinion or having a relevant public official accompany you.

However, from 2025, immediate viewing became possible only if you 'submit a doctor's written opinion and a relevant public official accompanies you'.

Based on this procedure, you request CCTV viewing, and if you subsequently find circumstances of child abuse or circumstances where the footage was intentionally deleted, proceeding with CCTV forensics may be necessary.

CCTV forensics is a procedure that, beyond simply viewing footage, scientifically analyzes matters such as attempts to recover deleted files, log analysis of the storage medium, and whether the footage was manipulated.

Where the daycare center provides only part of the footage or footage for a specific time period is missing, using digital forensic technology, you can confirm whether deleted or concealed footage exists.

However, in the case of digital evidence obtained through such forensics, it must have integrity and identity to be recognized as legal evidence.

This means that it must be proven that the submitted footage is identical to the original and that there was no change or damage after collection.

In addition, because digital evidence must go through a lawful process when collected, I will conclude my answer by stating that it must necessarily be carried out together with a digital forensics expert.
