Is there a system capable of recognizing and blocking obscene photos when they are uploaded to the site?

Question

PHP

There is a real estate website.
Users are free to upload pictures. There is no admin, there is no verification, that is, hypothetically, someone can put an obscene photo and it will appear in the catalog. Is it possible to use some kind of plug-in or tool on the fly that recognizes uploaded photos and checks them for an element, well, at least vulgarity?

Answer 1

"nudity detect" look, there are for different languages, for example
www.patrick-wied.at/static/nudejs

Answer 2

Not automatically, because For any nut there is a bolt with a reverse thread. The easiest and most profitable way is to install a moderator who will simply click on ads with photos in pre-moderation, if the volumes are large, then registered users with good karma can be given auto-moderation, and beginners preferably manually. Moreover, finding a moderator for such a task is not difficult.

Answer 3

real estate website. Who needs to post pictures like this?
there is a cheerful site, a photo country. there the picture is stored on the cloud.
the number of perverts and amateur nudes in the albums is off scale
, they are saved there by moderation, but the albums are moderated only by those that are public. you can upload anything to private albums and the girls will upload it.
Further, no algorithm will give a 100% guarantee. Try searching this image on Google. Even Google will make a mistake and give out a male torso and face, saying that these photos look like these boobs.

Answer 4

One of the simplest and least expensive solutions is the "report spam" button. It's just that users can not only upload vulgarity, but also seals, for example.
Well, in general, such a site without moderation IMHO is a bad idea.

Answer 5

nudity detect is the best but still something and it will climb

Answer 6

You can do as dimonchik2013 describes, set up the toughest filtering in it, and put a moderator on ambiguous or unclassifiable pictures, as AntHTML described it, and if such a picture nevertheless slips through to users, then give +1 to the first user who discovered such a picture something that can be exchanged for goodies on your site, well, you can enter achievements ...

Answer 7

For these purposes, you can use a neural network.
