Digital signatures cannot be trusted more than computers which compute them. As long as computers are not immune to attacks, other ways of ensuring integrity of digital documents have to be found. Visual cryptography and CAPTCHAs offer security which is based on human visual recognition capabilities, which are still unmatched by computers.
Real-world data are rarely two-dimensional and linear. Increasingly, they are not even numerical.

The example below visualizes relationships between hemoglobine alpha and beta chains of different species.
