How to Block Uploads of Nude Images

How to block upload adult or nude image?

You can use online services like the WebPurify Image Moderation Service. or try nudity detection service at Github or use Googles' Nudity detection service.

PHP - Blocking of uploaded adult images

Implement image premoderation. If there's a single person uploading those (like you imply), shouldn't be too hard for someone else to take a brief look and click "Approve" on each.

And it's way cheaper, and more reliable, than using any library. You cannot formalize "adult".

Restricting Inappropriate Videos when Uploading to App

If you are talking about recognizing nude images, then I'm very certain that you're out of luck. I don't think that you'll find anyt....wait a minute. I can't actually believe it.

I just went and looked for one to make sure that I was correct in saying that there is no nudity detecting API and voila! I found this:

Looks like that may be what you need. But in general, nudity detection is...not very easy to say the least. I don't think there is a simple algorithm you could implement. Your best bet is either to use that link that I just gave you, or create a system like YouTube has where offenses are punished fairly severely - things like copyright infringement and nudity result in a ban after just 3 times no questions asked.

I hope that helped. good luck!

What is the best way to programmatically detect porn images?

This was written in 2000, not sure if the state of the art in porn detection has advanced at all, but I doubt it.

PORNsweeper seems to have some ability to distinguish pictures of people from pictures of things that aren't people, as long as the pictures are in colour. It is less successful at distinguishing dirty pictures of people from clean ones.

With the default, medium sensitivity, if Human Resources sends around a picture of the new chap in Accounts, you've got about a 50% chance of getting it. If your sister sends you a picture of her six-month-old, it's similarly likely to be detained.

It's only fair to point out amusing errors, like calling the Mona Lisa porn, if they're representative of the behaviour of the software. If the makers admit that their algorithmic image recogniser will drop the ball 15% of the time, then making fun of it when it does exactly that is silly.

But PORNsweeper only seems to live up to its stated specifications in one department - detection of actual porn. It's half-way decent at detecting porn, but it's bad at detecting clean pictures. And I wouldn't be surprised if no major leaps were made in this area in the near future.
