Prove a person wrote it, not a bot, from how they typed, without ever sending what they typed.
Open Human Keys →Human Keys records how someone types: the gaps between keys, the corrections, the thinking pauses and whether anything was pasted. It never records what they type.
The text is fingerprinted on the writer's own device and only the fingerprint is sent. The typing rhythm is scored, and the fingerprint and score are sealed into the chain with a check page at sebbi.pro/k/<code>, which can also be anchored in Bitcoin.
Writers, students, job applicants, journalists and anyone who must prove human authorship.
