Safety? Ever wanted to have a skin filter on your Minecraft server?

Now you are able to check if a Minecraft skin is sus (aka. not child friendly). The system detects how similar a skin is to an existing flagged skin in the database.

Technical

The only thing you provide is the skin hash (the id Mojang gives your skin) and then the server tries to find it locally. If it can’t be found locally then the skin is downloaded directly from Mojang. After that step each pixel that is valid for a skin is compared against every pixel of flagged skins and a percentage value is calculated from 0 to 1.
Meanings:

• 0 not similar at all or an error has occurred
• 1 identical image

0.95 = 95% similarity

Practical use

This system will be improved in future to be more reliable against false positives. I am planning to create a Minecraft plugin that does this job for you

Ahh btw. The server takes ~10-20ms to process one request at the moment. (it is a really old one haha)

Current false positives:

• toddler/baby skins (they have tons of skin)
• (almost) fully yellow skins (confuses these skins with a skin that contains symbols illegal in Germany)
