Fingerprinting infers similarity from attributes; key-based binding proves a particular registration. Their certainty and privacy properties differ.
Evaluation approach
Assess resets, changes and false matches while minimizing collected data.
Application example
A legitimate device change needs a verified new-registration path rather than permanent lockout.
Limits and considerations
A permanent, infallible device identifier is unrealistic in many mobile settings.
Handling mistaken matches
Similar attributes need not identify the same physical device. Provide appeals and re-registration and explain identifier limits without claiming permanent recognition.
Checks and decisions
- Plan changes
- Minimize data
- Provide recovery
