Biometric identification
is the technology to identify an individual by using the |
|
|
biometric characteristics
of people. |
|
|
|
|
|
Primary security device |
| |
Physical key, card,
token |
| |
System : ID, Password,
certificate encryption |
| |
|
| |
Secondary security
by biometric authentication |
| |
Guarantee of the safety
for identification and authentication. Uniqueness and |
| |
continuation |

Identification System's
permanency and unchangeableness are verified and |
| |
this system is used
generally due to the convenience. Like this system, 1:1 |
| |
system that finds the
most similar fingerprint from the huge database is a kind |
| |
of identification system
to verify the fingerprint after a user in the fingerprint
|
| |
database gives his/her
ID. There can be the middle system between two |
| |
systems (1:Few) that
identifies without entering his/her ID. There are two |
| |
procedures to identify
fingerprint, first procedure is to select the templates |
| |
from the fingerprint
image and the second one is to compare the templates. |

b. Hole caused by sweat

c. State of causing
short ridge |

 |
| |
Fingerprint identification
Algorithm (Template data of 480bytes) |
| |
 |
| |
Volatile image is shown
in the user program and templates are saved through |
| |
encryption (Aes, DES,
3DES, Seed) in the database, registry and user file |
| |
system. |

Perfect identification
method |
| |
Rejection of the same
fingerprint data even though the information is hacked |
| |
Impossibility to convert
selected and saved data into an image |
| |
It is possible to construct
with low cost comparing with other biometric |
|
identification products |
| |
There is a difference
from invasion of privacy because fingerprint image is |
| |
not used. |
