As of this moment, it's an unknowable black box. That said, apple has stated that the system will match on a photo even if it's been resized, shifted formats or been otherwise altered. It is NOT a simple file hash. In order to create a hash that survives re-encoding or resizing, content analysis must be happening. Whether that changes your calculus or not is another matter entirely.
