"At its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we can't predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe."

![]() 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.
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.
It turns out that Herbert's palm lock is not the earliest reference in science fiction to this kind of biometric identification system; see the palm plate from The Mechanical Monarch, a 1958 novel by E.C. Tubb. Comment/Join this discussion ( 2 ) | RSS/XML | Blog This | Additional
