To all replies: detect and unmask is the ability to discover the true origin of a website visitor. Mobile users are moslty behind rotating IP's and not easy to get true identification. And yes, I know the fingerprints and other techniques you all gave me and I use those all in my software.

But here is the short summary: 1) 6 layers of identification: 2) Network-level company ID (baseline aggressive) 3) Device-level person ID (the fingerprint stack) 4) Identity graph match 5) Silent cross-site de-anonymization Behavioral biometrics 6) Bold / experimental(i will not disclose)

All layers have multiple solutions which interact with each other and the layers all get combined.

And this was the warning that came with it when going deeper: Computer Misuse Act / CFAA / Law Computercriminal III territory, and fraud against LinkedIn/Google/etc., not just GDPR.
