System Development Life Cycle

Lacrimal Biometric System Co.Today I will be doing a demonstration with a demo kit from Aviation Communications Limited. (AVCOM)

I will use a prototype to demonstrate the biometric system as the system is not yet available.

The system was tested as a dual with the ISONAS and the results were admirable.

A user manual is available for proper use of the system

One point of interest that might arouse curiosity concerns the tear analysis.

It should be noted that a couple years ago it took months to analyze a human DNA. Today it has been proven that DNA results can be ready in


less than 2 hrs. It should also be noted that if the tear specimen should be place in water to keep it moist the DNA composition will be disturbed thus the DNA results.

Here are a few pointers on collecting the specimen.

1. Remove the swab from the wrapper

2. Place tip of swab at outer cantus of eye and blink to collect tears (ensure that swab does not touch the cornea “white area” of the eye as this could cause damage)


3. Remove swab from eye and quickly place tip in Biometric device.

4. When you see a red light that indicate that the specimen is accepted.

5. Remove swab from device and discard into garbage bin


DUAL SYSTEM AT WORK

The software of the ISONAS system will have added credentials of employees.

Whereas it was only the credential on the key fob it will now be both the key fob and the DNA analysis in the form of binary codes (computer numbers).

The ISONAS device will no longer accept just the key fob information because it is now a dual system.

The database likewise will be accepting more information from the software

If the information match up the door lock will be opened in less than 1 minute and the employee can enter the building.
