That sending nude pictures of yourself to Facebook isn't a great idea ?

[LurkingHusband]

Yes, really:

Facebook has begun conducting a pilot where it solicits intimate photographs of women – and it will soon offer the service in the United Kingdom. Anxious exes who fear their former partner is set on revenge porn will be urged to upload photographs of themselves nude.

A hash of the nude image is created and passed along to Facebook's AI image-matching systems. Subsequent unauthorised attempts to post on one of Facebook's services (including Instagram), the image are then blocked.

(contd).

Or am I just a bit of a fuddy-duddy (as my late DM would say) ?

Police use hashing values of known illegal images to identify / flag up the distribution of those illegal images. However, I can’t see anyone willingly sharing nude images of themselves with Facebook to hash them given the potential for others to hack their servers. It’s also assuming that one owns every single nude pictures of yourself.

It doesn't make a difference, the app would belong to Facebook, and use their encryption methods, it makes no difference if that encryptions done on your device or their servers. If you own an app you have access to all the data that people use it for.

@IvorHughJars

I think a better comparison would be 'don't have unprotected sex if you don't want a baby'. The advice 'don't send nudes of yourself if you want them kept private' isn't victim blaming.

"Or maybe Facebook could implement some decent safeguards to prevent users from being able to upload any explicit material?)"

Like what? I get it that some people like to lever the word 'safeguard' into conversations but what do you possibly imagine could be implemented?

"how's about some posters in men's loos that say Don't Rape, for example?"

I wonder how many people, about to rape, would remember a poster they'd seen when in the toilet and thought, "you know what, I won't rape"!

I suspect none.

Facebook explain:

A determined person would simply run any pics though a couple of filters, and hey Presto ! a new image that doesn't match (despite what Facebook claim).

They are using the metadata attached to the photo. You need a very high skill level to remove all the metadata from an image. The metadate contains all manner of inbuilt info like when the ohoto was taken, on what device, how it was processed, where it has travelled etc etc.
Even if you use 45 filters through 6 apps, the original meta stamp will remain. It's kind of like a really complicated postcode for your image, if that makes sense?
The image is not required so much as the metadata behind it.
It's not gonna be a big Facebook nudie stash, waiting to be hacked.
I agree with other posters though that think it could be manipulated for trump to take down images of his little teensy hands (maybe anyway)

You need a very high skill level to remove all the metadata from an image.

or any number of free websites, apps or programs. Phatch can do thousands in one hit.
