Additional commonly asked Q&A related to ‘Device Fingerprinting’ in DFP continued

Yes, it is possible for several unrelated customers to get the same device fingerprint ID. This can happen due to several reasons:

1. Shared Devices: If multiple customers use the same device, such as a public computer or a shared tablet, the device fingerprint ID generated will be the same for all users of that device.
2. Similar Device Configurations: Device fingerprinting relies on collecting various attributes like hardware information, browser information, geographic information, and IP address. If two devices have very similar configurations and settings, they might end up with the same or very similar device fingerprint IDs
3. Network and Proxy Usage: If customers are accessing the service through the same network or proxy, the IP address and some network-related attributes might be the same, leading to similar device fingerprints.
4. Limited Attribute Variability: In some cases, the attributes collected might not be diverse enough to uniquely identify each device, especially if the devices are from the same manufacturer and model.

These factors can contribute to the generation of identical or similar device fingerprint IDs for different customers. If you have any more questions feel free to ask.
