I am not exactly sure if this is how this works but it appears to me that all the hashes of your photos get uploaded to a server and was wondering if it is possible to reverse the hashes to be able to deduce what's in each photo hashed..
Your answer without an explanation doesn't amount to anything more than a scant opinion. "no and no" isn't worth commenting on hackernews in my opinion. As I stated above, I am not very familiar with how this bleeding edge technology works but am not learning anything new from your response. If you wanted to expand I'd appreciate it
