As in all good
application designs, it is the business process requirements which
should drive the design - not the other way around. Similarly the
specific type of biometric chosen, i.e., fingerprints, iris codes,
hand geometry etc. should reflect the application requirements - the
application should not be a slave to an individual biometric
methodology.
A successful
application development and deployment scenario may follow a path
something like the following;
Identify the business and operational requirements clearly, together
with any current problems and the effect they are having on the
situation.
Develop and agree a suitable business process which has the
potential to significantly improve on the current situation, given
the current state of technology.
Quantify the operational logistics such as (in an access control
context) number of people, time profile / distribution of
transactions, type of entry point, target transaction time,
environmental considerations, availability and profile of system
operators and so on.
Analyze existing situation and processes in order to identify legacy
requirements and system interaction - it may be necessary to retain
or assure compatibility with certain existing processes.
Design a system architecture which accounts for all of the above
whilst remaining open for future development and enhancement.
Design an operating methodology and user interface which satisfies
the above requirements in an intuitive and attractive manner.
Choose the appropriate front end technology accordingly (i.e.,
biometric / biometric and chip card etc.) ensuring that the
biometric methodology is the most suitable for this application.
Interface the biometric / token technology with your system.
Thoroughly test and document the system in house before
demonstrating the system to the client and agreeing and documenting
any design changes.
Develop and schedule an operator training programme together with
the provision of system manuals as necessary.
Install and commission the system having surveyed the site and noted
relevant conditions and with due consideration to existing systems.
Hand
over the system after ensuring that operators have a comprehensive
understanding of the functionality and that all operating data is
present and correct.
