"I love that computer science has made mathematics into something like an experimental science. I was never all that good at proving things, but I love doing computer experiments."
- Rudy Rucker

| Palm Lock | ||
| A lock or seal which can be opened only by contact with the palm of the human hand to which it has been keyed. |
This is another wonderful creation of Herbert's. It is not clear if the lock is part of the knob or device that opens the door, or is just a lock.
| Jessica put a hand on the rail, began to climb. The rail felt cold under her sliding palm. She stopped at the door, saw it had no handle, but there was a faint depression on the surface of it where a handle should have been. Surely not a palm lock, she told herself. A palm lock must be keyed to one individual's hand shape and palm lines. But it looked like a palm lock. And there were ways to open any palm lock--as she had learned at school. Jessica glanced back to make certain she was unobserved, placed her palm against the depression in the door. The most gentle of pressures to distort the lines--a turn of the wrist, another turn, a sliding twist of the palm across the surface. She felt the click. |

Fingerprints are held to be unique; I wonder if a human palm offers more points for comparison, and is therefore more secure?
The need for greater data security has led to the use of a variety of biometric identification system. Recently, a device as small and inexpensive as a Pocket PC was made available with a reliable fingerprint scanner.
Significant work has been done in the last few years on palmprint identification. Some potential advantages may exist; the hand geometry and major palm creases can be captured using a lower resolution device. The device in Dune seems to rely only on the print.
Compare to the palm plate from The Mechanical Monarch, a 1958 novel by E.C. Tubb.
