Recommendations:
Project recommendations and Author's note: Users of the system are urged to use care in handling the optical box since precise measurements are taken for correct alignment of the lens and ccd sensor. If the box is subject to a fall or vibration then these necessary alignments might go out of place, making the image blurry on the sensor and thus reducing system performance. It is also a good idea to keep the database under maintenance, cleaning up old or duplicate users. This will make things simpler when or if the database's internal data needs to be reviewed or checked. Planned Upgrades: In conclusion, we have seen how our linear biometric identification system works. It is a linear hand geometry reader, which possesses the same basic characteristics of any 3-D hand geometry system. Although the system relies on the CCD resolution, it is almost imperative to have a good detection algorithm in play. That is why we have employed two detection algorithms: static and dynamic that have been explained above. These algorithms are the sole key to producing and effective and reliable identification system. These algorithms are based on the statistical properties of every user’s fingers and are therefore unique for each person. However, this system is no complete. We have written down several optimization criterions that we could add to this versatile system. 1) Stand-alone System: The integration of a data ROM, to include the user database and a System BIOS to contain the Operating System of the device (synchronization procedures, scanning, writing, etc.) 2) An upgrade to the optical lens: In order to reduce the size of the optical box. 3) The use of a laser light source in order to have no noise on the CCD due to light. This way a light filter will not be necessary. 4) The incorporation of a keypad for system input. This will include PIN entry. 5) An LCD display to let the user know the results of their scans. 6) A bar code reader. This will implement the use of a PIN card. Which includes the user’s basic info and will locate the user’s entry on the database upon reading. These are some optimizations that can be done to this system in order to provide a more reliable and secure identification system.
