Show HN: Neural-hash-collider – Find target hash collisions for NeuralHash
Despite that Apple scanning our images is
a horrible privacy practice, I don&#x27;t get why
𝚜̶𝚘̶ ̶𝚖̶𝚊̶𝚗̶𝚢̶ some people think this is an ineffective idea.<p>Surely you can easily fabricate innocent images
whose NeuralHash matches the database.
But in what way are you going to send them to <i>victims</i>
and convince them to save them to their photo library?
The moment you send it via WhatsApp FB will stop you
because (they think) it is a problematic image.
And Even if the image did land, it has to look like
some cats and dogs or the receiver will just ignore.
(Even worse, the receiver may report you.)
And even if your image does look like cats and dogs,
it has to pass another automatic test at the server side
that uses another obfuscated, constantly-updating algorithm.
After that, even more tests if Apple really wants to.<p>That means your image needs to <i>collide</i> ≥ three times,
one open, one obfuscated, and one Turing.<p>Gmail scans your attachments and
most people are cool with it.
I highly doubt that Apple has any reason to withdraw this.
