Abstract
A method of distinguishing between human-generated text and text generated by artificial intelligence (AI) is disclosed. A plurality of first cryptographic digital signatures associated with a set of typed characters are generated. Generating the plurality of first cryptographic digital signatures may include, for each of multiple keystrokes on a physical keyboard: detecting a motion associated with a pressing of a particular key on the physical keyboard, wherein the particular key is associated with a particular character; generating a first cryptographic digital signature associated with the particular character in response to detecting the motion; and providing a typed character and an associated one of the first cryptographic digital signatures to a first verification entity located within a processing device, for verification of a physical keystroke.
