Components:

No.	Module	Platform	3rd Party Module	Miscelleneous
1	Master Server	Windows	BEA WebLogic	WAS(Application Web Server)
2	DB Server	MS-SQL / Oracle		eNBSP SDK
3	Search Server	Windows		eNBSP SDK

1. Master Server:

• Operating at J2EE-based WAS

• At the request of a client, delivering it to sub system and showing the results to the client

• Monitoring status of each sub system and performing load balancing

• Can use L4 switch for duplex ‘Master Server

2. Search Server:

• Processing a fingerprint authentication request from Master Server

3. DB Server

• A system in which RDBMS such as MS-SQL and Oracle operates

• A system saving fingerprint-related data

Server System Specification Recommended

Item	Description	Remarks
OS	Win 2000 SVR and higher		Requiring 2 sets of the above system for duplex server system (incl. L4 switch) The above system can authenticate 20,000 and more cases per minute (in case of Oracle) System spec. including HDD can be varied depending on a user’s operation environment
CPU	Pentium4 3Ghz * 2
Memory	4GB
HDD	30GB and more
WAS	WebLogic 8.1	BEA
DBMS	MS SQL or Oracle

System Advantages:

1. Various Authentication Environments
Can authenticate fingerprint using web browser and perform C/S authentication using SOAP protocol from web service. No restriction of firewall because of use of web service.

2. Support of a variety of OS and quick & easy acceptance
No limit of OS type because master server operates on J2EE-based web application server. Because of middleware type, system integration can be appropriately performed.

3. Compatibility with a variety of fingerprint recognition devices
Also, compatible with other fingerprint recognition devices, not NITGEN’s device.

4. Load Balancing / Distribution structure, Extensibility / High Availability

• Improving performance through distribution between master servers by using L4 switch.
• Each unit server can communicate with one another through CORBA and JDBC
• Can extend master server and search server in case of increase of users.
• Since a client accesses to master server through load balance, it recognizes as a system

5. Separately operating AES Key site by site by using 128 Bit AES algorithm

• Fingerprint data is encrypted as soon as being extracted from a client and the data is encrypted again by AES algorithm

• Highly secured because data is saved after AES encryption when being saved and decoding is not possible because different encryption keys are created site by site although the data is revealed

6. Reinforced fingerprint data security (prevention of fraudulent use of DB)

• Designed to protect fingerprint data from being authenticated although using fingerprint DB
  at different sites
