Clone Detection Engine
The first and only clone detection system for Roblox UGC. Four proprietary fingerprint layers. Continuous catalog monitoring. Instant alerts with DMCA-ready evidence.
The Threat
Studio plugins extract any catalog model as a raw mesh file. The thief re-uploads it to their own group — unmodified, 1:1. By the time you notice in the catalog, they've already captured your sales.
The theft
Plugins load your mesh directly from the catalog. Export. Re-upload. Zero modification needed — pure 1:1 duplication.
The abuse
When you file DMCA, cloners file false counter-claims. Roblox's automated system accepts them and the stolen item stays live.
The false strikes
Roblox's own AI moderation flags original items as stolen — applying permanent account strikes to legitimate creators.
Shield solves both sides: detect real clones before they steal your revenue, and pre-screen your items before upload to avoid false AI strikes.
The Pipeline
Every registered item passes through a proprietary detection pipeline. Here's what happens when you enter an Asset ID.
~2 seconds
Shield authenticates with the Roblox Asset Delivery API and downloads the raw mesh file and texture map. This requires API authentication that most tools can't access — a barrier that protects Shield's crawling capability.
~500ms
The Rust-compiled WASM engine processes your asset through perceptual image hashing, geometric metadata extraction, 3D shape distribution analysis, and texture fingerprinting. Each layer produces a compact, one-way fingerprint — it can identify clones but cannot reconstruct your original asset.
Permanent record
Your fingerprints are stored alongside a timestamp proving when Shield first saw your item. This 'first-seen' record is critical — in a DMCA dispute, it establishes who uploaded first. Competitors starting later can never backfill this history.
Every 15 min
Every 15 minutes, Shield crawls the newest Roblox catalog uploads. Each new item is fingerprinted and compared against every registered item in the database using vector similarity search. The HNSW index returns matches in milliseconds, even across hundreds of thousands of fingerprints.
Instant
When a potential match is found, all four layers produce a weighted composite confidence score. Items are classified as High, Medium, or Low confidence — not raw numbers, but clear threat levels you can act on immediately.
Instant
You receive an instant notification with the suspect item, confidence breakdown per layer, and a side-by-side comparison — everything formatted for a DMCA takedown filing. No manual evidence gathering. No guessing if it's really a clone.

Why Shield
The entire Roblox third-party ecosystem focuses on game analytics and trading data. For UGC accessory IP protection, there is nothing. Shield is the first and only.
Every fingerprint carries a 'first-seen' date. In a DMCA dispute, this proves who uploaded first. After 6 months, Shield will hold hundreds of thousands of timestamped fingerprints — a dataset that cannot be replicated by anyone starting later.
The detection engine is Rust compiled to WebAssembly. The binary contains no variable names, no comments, no readable source. Even knowing the general approach, no one can extract Shield's specific parameters, thresholds, or scoring weights.
Since April 2025, Roblox requires authentication for asset delivery. Setting up and maintaining authenticated crawling with proper rate limiting is a non-trivial barrier that most tools haven't crossed.
More creators register → bigger database → better detection → more creators trust it. The first tool to reach critical mass wins. There's no room for a close second in a network-effect market.
