device detection

Precision data and technology company 51Degrees is launching a new product that will help website owners, advertisers and their technology partners to filter and manage non-human traffic in order to save costs, protect their IP and boost the value of their human audiences.

Human Confidence tells you, in one word and in real time, how sure you can be that a person is viewing the page.

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.

Applications, proxies, and analytics platforms often lowercase or otherwise normalize User-Agent strings before they are processed. This blog explains why a User-Agent is structured data rather than ordinary text, what is lost when it is modified, and the best practice for keeping device detection accurate.

Your iPhone or iPad has an AXXXX code printed on the back or buried in Settings. It tells you which model the device is, but only if you have the mapping. Here is the full A-code to device-name reference 51Degrees uses, along with a note on how Apple's three different identifiers fit together and where to find each one.

In this session, we'll live code Go to bring IP and device intelligence together. We'll cover:

• Multi deployment options including in memory, on disk, and in application process
• Consuming both device detection and IP intelligence as a single service
• Switching between cloud and on-premise
• Auto updating on-premise data
• Real customer use cases that add sparkle to any website or analytics
