Absolutely! We all basically do fingerprinting. We’re just not really conscious about the key we are using. But with a bit of statistics, you could identify people.

• Only the key-holder can check. Your teacher, editor, or favourite “AI detector” website cannot run this test; a genuine check needs the provider’s secret key, or a checking service the provider runs.
