 Yes, this would work even better! If the ink just contained your
DNA, someone could use PCR to duplicate it! If you actually signed
in blood, they would have to match the type and if a white blood
cell was there they would have to "forge" the mitochondria since
they have different DNA! This is not to mention other blood
factors.

 There is prime material here for Klaus! on the the difficulties of
running "blood remailers" "anonymous bloodletting," etc.....
