Abstract


Lock and Key System is archaic


New technologies, either incorporating memory or
biometrics, can help security move beyond the
antiquated system of lock and key.



Memorization adds security


But passwords can be forgotten, shared, or observed



Most effective security is Biometrics


Biometric technology is a way to achieve fast
and user
-
friendly authentication with a high
level of accuracy


What is Biometrics?


Biometrics is an automated method of recognizing
a person based on a physiological or behavioral
characteristic.



It can be used to uniquely identify one person from
another.




Includes fingerprints, speech, face, retina, iris,
handwritten signature, hand geometry, and wrist veins


By using an attribute of the body, security is improved
because there is no room for human error



Using Biometrics security will increase system
effectiveness.

Design Objectives


The Digital Door Assistant will:



Provide a convenient, reliable, and secure
alternative to archaic key
-
entry door systems



Utilize accurate fingerprint identification in
order to allow access for authorized users



Perform as an embedded system geared for
residential use

Choice of Fingerprint Device


The MV1200 fingerprint scanner:


Unlike many other scanners, is made
for embedded devices


Is capable of interfacing with a
microcontroller


Contains an accurate identification
algorithm onboard


Allows for administration over
templates (addition and deletion)
