It's a collection of data points from a user's device that, when combined, create a unique and persistent identifier. This "fingerprint" is designed to be highly resistant to changes and can be used to identify a specific device, even if the user tries to clear their cookies, change their IP address, or use a different browser.
A "Stable Device ID" is exactly what it sounds like: a unique identifier for a device that remains the same over a long period. This is the goal of fingerprinting. The "Stable Device ID" is the result of the fingerprinting process.
This is the whole point of fingerprinting! If a user changes their device ID, the fingerprinting method is designed to still recognize them. Let's imagine a scenario:
5f8c6d4e-b9a1-4c7a-8b3d-7e2f1g9h4i5j
).5f8c6d4e-b9a1-4c7a-8b3d-7e2f1g9h4i5j
).This allows you to link the two visits to the same user and device, even though they tried to hide their identity.
So, in summary, you're not using a "fingerprint option as a Stable Device ID." Instead, you're using a "fingerprinting method to generate a Stable Device ID." This Stable Device ID is what gives you "control" by allowing you to track a user even if they try to change their device ID.
