Isn’t the point map supposedly encrypted on the Secure Enclave?[a] If it is, you can’t access it from the main CPU; you can only ask it to compare a provided one with the stored one.

The verifier point cloud used for unlocking the phone must be kept in the secure element.

That doesn’t mean you can’t read a point cloud for other purposes.

They currently expose ARPointCloud API but I don’t know what sensors it uses to produce it;
