Homonin is designed so your health record is read and sealed on your phone, with a key we never hold.
For most of history there was one chart, in one building, pointing at one person.
Then the copy was copied: portals, insurers, apps, brokers. Every copy is another place to leak.
Homonin models you as a biodigital twin. Anything that intimate needs walls: here is where your record is read, where it is sealed, and what we hold afterwards.
Nothing readable crosses the line. The vault holds sealed records and a log of who touched them.
Your record is sealed before it leaves your phone. We can keep it safe, but we can't read it, sell it, or hand it over readable.
Illustration. Real ciphertext is produced on the device, with a key we never receive.
A lab result shown in plain text on the phone, then as unreadable sealed text, which is all Homonin would store.
