What is the difference between authentication and identification?

In short, it is 1:1 versus 1:N.

Authentication is the 1-to-1 process where we verify if the typing pattern belongs to a particular user. This is what the TypingDNA solution does.

Identification is the 1-to-many process where a typing pattern would be compared against all the typing patterns in existence to verify whom it belongs to. TypingDNA does NOT offer identification solutions.
