csam

Initialism of cold spray additive manufacturing.

Initialism of child sexual abuse material.

Apple’s plans were struck a significant blow two weeks after they were announced, when security researchers managed to reverse engineer the “perceptual hashing” algorithm the company intended to use to identify known CSAM that was being uploaded.

The ability to produce infinite images powered by datasets containing millions of photographs of real people, including children, and real images of real CSAM, perpetuates abuse in a way that was previously impossible.
