Why these matter
If someone receives a voice message or call claiming to be you — they ask for the phrase or the fragment. A synthetic voice doesn't know it. Your voice does.

SongSecure
Your voice. Your song.
Choose a song as your public voice identity. Issue fragments of it as private keys to your circle — a different fragment for each person.
How it works
Anyone can know your song. Only the people you tell know which fragment is your key. If someone's unsure it's really you — they ask for the fragment. Your voice confirms it.
