Developers working on model protection just found something interesting—embedding invisible fingerprints into AI systems. The approach works like a digital watermark: it lets creators verify whether their models are actually being used or simply copied without consent.

What makes this technique compelling? The fingerprints stick around even after models go public. Ownership verification becomes possible without exposing the model architecture itself. It's essentially adding a proof-of-ownership layer that survives distribution, tackling a real problem in the AI commons.
