I got to reading the MicroSignet patent and was wondering just how selected cells are found.

Look at page 12, Fig 6,

Process 600, Perform read on selected memory cells; and 610, Determine variation from written data.

Wouldn't you say this to be the 737 at work?

I also fount it interesting page 12 , 10-20, that the higher the error rates the more secure and identifiable the fingerprint becomes.
