Fujitsu unveils palm-reading security mouse

Ronald Larsen

** Cool but ...

On a whole series of assumptions: Other than irritation, what would be the point?

No access to be gained: I assume the vein patterns are stored within the computer, not the mouse. (Storing the patterns in the mouse itself would be a Very Bad Idea.).

Within a company-setting, a replacement mouse could be hooked up and everything is as before.

No use for it: I assume that the mouse requires special software to function. The mouse alone would not help.

The one question that I had is why the blood has to be flowing in order for the vein patterns to be checked. Since the scan light is near infra-red, does this have to do with the warmth in the blood? (useless than with most vice presidents) Or is there a type of doppler measurement going on?
