"best" by itself is a term with no objective meaning. For example, which
is "best", a bicycle or a Rolls Royce Silver Ghost? If you are trying to
get around in Inner London, then numerous races have shown that the
bicycle is faster.

With regard to a software system, the "best" approach would have to be
interpreted as one that had been demonstrated to be incapable of being
improved. Is there a complete theory of fingerprint identification? No
there isn't -- and hence until such a theory is arrived at, anything we
tell you is "best" now with the current state of the art, might be
improved on, perhaps tomorrow, perhaps not for another 50 or 60
millenium. If we tell you the "best" approach now, and someone/something
were to find a better approach 5 or 10 million years from now, then
obviously we didn't tell you the "best" approach. I, for one, cannot
afford liability insurance against the possibility of theoretical
advances more than 3 days in the future.


My _personal_ interpretation of "best approach" for such a system would
be: "Don't Do It At All!"

The EU and Canadian privacy laws would levy some very considerable fines
if a flaw in your system allowed biometric information to escape. Matlab
and Excel were not designed for security to the legal level you would
need to use to satisfy the privacy laws, and Dutch researchers (I think
it was) have shown that nearly all commercial fingerprint readers were
_easily_ hacked.

Thanks for the reply...

I did look up for some matlab coding example for fingerprint identification..

I'm doing a final year project. I'm not planning to use it for security.Its just for class attendance. That I hope can integrate with Microsoft Excel.

Are there fingerprint scanner can be use with MATLAB?
Is it possible to integrate to integrate with EXcel?
This is just a educational use.

Biometric data is "personally identifying information" for the purposes
of privacy laws. Access to biometric data must be controlled under those
laws. Excel has effectively no security, and Matlab's security is not
especially strong.

It does not matter that you would not be using the biometric data for a
security application: what matters is the security you implement to
prevent the possibility that someone could steal the biometric data. And
as you did not understand this, the probability that you could learn
enough about security to do this properly within the time-frame of your
project is fairly low: this is something that a lot of security
practitioners get wrong.
