Cyber strategies used to combat child sexual abuse material

Cyber strategies play a role in combating child sexual abuse material (CSAM). These strategies aim to detect offenders and prevent them from accessing and producing CSAM, or to identify victims. This paper explores five cyber strategies: peer-to-peer network monitoring, automated multi-modal CSAM detection tools, using web crawlers to identify CSAM sites, pop-up warning messages, and facial recognition. This research synthesis captures the background of each strategy, how it works and the evaluative research, along with the benefits, limitations and implementation considerations, offering a practical overview for a broad audience.
