What technical methods do platforms use to distinguish CSAM from child erotica and what are their limits?

Platforms combine signature-based matching and machine learning to separate illegal child sexual abuse material (CSAM) from broader categories like child erotica, but each method has brittle edges: ha...

How effective are current AI classifiers and hash‑matching tools at distinguishing synthetic CSAM from real imagery?

Current and perceptual/hash‑matching tools form complementary lines of defense: hashing reliably identifies previously documented with very low false positives but fails on “new” or synthetically gene...

What legal defenses exist for someone who accidentally or briefly landed on a hidden-service CSAM page?

Accidental or momentary access to a hidden-service page that contains child sexual abuse material (CSAM) does not automatically equate to criminal liability; common legal defenses include lack of inte...

How do automated hash‑matching systems work and what are their limits in identifying CSAM?

Automated hash‑matching systems detect known child sexual abuse material (CSAM) by converting media into compact "hashes" and comparing them to databases of verified CSAM hashes, enabling fast, scalab...
