Watch your fingers

Science News,  March 10, 2007  by Paul Schlueter, III

Regarding "Digital Fingerprints: Tiny behavioral differences can reveal your identity online," SN: 1/13/07, p. 26), Morse code "fist" analysis can easily be defeated by a software buffer that conforms the intervals between all types of strokes. Actual Morse buffers are already in regular use among ham operators. "Writeprints" can also be defeated. "Clickprints" aren't as easy to coneeal, perhaps, but some clever software designer will devise a foil for them too.
