51Degrees launches 51Did, a new Digital Advertising Identifier
51Did is an identifier you can actually check. Check what it does inside your own business, and what changes when it travels.
Almost every digital advertising identifier on the web arrives in a request, gets read, and is assumed genuine by everybody downstream. A copied identifier behaves exactly like a real one, because it is real. 51Did is an identifier you can actually check, signed so anyone receiving it can confirm it is genuine and that the device, browser and connection it was created in have not changed.

Your ads have an audience. Does it have a pulse?
Autonomous AI agents browse in real browsers, on real devices, from real addresses. Here is how to tell whether a human is involved.
There is now a third kind of visitor, and it fits neither box. Autonomous AI agents drive genuine Chrome, on genuine laptops, over genuine residential connections, so nothing in the request is fake and every check you already run passes. HumanConfidence reads eight device and network signals in one call and returns High, Medium, or Low, with the recipe published so you can check the working yourself.
