> "How does a fingerprint remain stable over any reasonable period of time?" Depends on how stable the signals being used are. Some can be very durable. > "How do you distinguish between different user accounts on the same device?" Fingerprints usually identify a device or specific user-agent. I'm not sure about the context for this but you can augment it with cookies to specify "user accounts". > "How do you tie a fingerprint to your database of existing customers?" How do you tie any random alphanumeric ID - whether stored as a cookie on device or recognized as a fingerprint - to a customer? Mappings still exist and work the same way. > "How do you keep cookie data from conflicting with fingerprint data?" What would be the conflict? Ideally only one is used as the primary identifier and takes precedence.
