Hi,
Some grammer correction for 3.
3. The finger print database is closely linked to a finger print
encoding. While doing search, finger print picked up from the field is
used to generate a match pattern, then the encoding method determines
how the match pattern is generated. Finally the match pattern is used
to scan all database data to see if there is any match between one of
stored finger print data with match pattern data. That means, for
example, one full set of finger print needs 256 bytes, a match pattern
has its 256 data, then a comparison is made between the 256 bytes to
see if they are matched. During match process some bit comparison
results are masked or
some bits are masked before doing match. In search process, I think
there is no need to know how finger print is encoded. Is it correct?
Thank you.
