Abstract

The researchers designed a prototype that provided an easy access to locker and secured the things inside. The prototype was designed to aids the limited locker the faculty members used that equipped with fingerprint biometric technology in accessing the locker. It also promoted the school vision of leading in the development of information technology innovation. It was designed to have administrator for maintaining the system continues operation and managed the enrollment of the users. In terms of components, all was available in local marketplace and the prices were suitable to their functions. The system was a user friendly. The prototype was design to be implemented to AMA Computer College Lucena Campus. In this study entitled “PC-Based Fingerprint Locker” the proponents were able to design a system that would be used for the security and provided an easy access to the lockers of the faculty members. Recommended generator not only a UPS helped a lot in continues operation of the entire system in case of power interruptions and using the PC for alarm system instead of external buzzer also consumed electricity.

I. Introduction

Technology indeed has essentially developed and advanced a person’s living condition. People now live in an industrialized civilization where state-of-the-art innovations seem to appear at an increasing rate. The range of such technological breakdown in terms of new products, processes and organizations is so wide. As the saying goes, today’s breakthrough can easily become tomorrow’s history.

In an increasingly digital world, reliable personal authentication has become an important human computer interface activity. National security, e-commerce, and access to computer networks are some examples where establishing a person’s identity is vital. Existing security measures rely on knowledge-based approaches like passwords or token-based approaches such as swipe cards and passports to control access to physical and virtual spaces. Though ubiquitous, such methods are not very secure. Tokens such as badges and access cards may be shared or stolen. Passwords and PIN numbers may be stolen electronically. Furthermore, authorize user and a person having access to the tokens or knowledge is cannot be differentiated. Biometrics has emerged as one of the most convenient, accurate, and cost-effective forms of security.

Biometrics such as fingerprint, face and voiceprint offers means of reliable personal authentication that can address these problems and is gaining citizen and government acceptance. The use of fingerprints as a biometric is both the oldest mode of computer-aided, personal identification and the most prevalent in use today. However, this widespread use of fingerprints has been and still is largely for law enforcement applications.

Summary

In this study entitled “PC Based Fingerprint Locker System” the proponents were able to design a system that would be used for the security and provide an easy access for the lockers of the faculty members.

The main problem of the study is to design and develop a prototype that can be used for security, thus the proponents attempted to create solutions.

Specifically, it sought to answer the following.

1. What design prototype will provide easy access to lockers?
2. What design prototype will provide secure storage for personal belongings?

Conclusion

Based from the study conducted and the result obtained from series of testing the researchers concluded that the PC-Based Fingerprint Locker had provide an easy access to the lockers and also provided a secure storage of personal belonging of the faculty members. This study had the capacity of being one of the technologies for securing things in the locker which has primarily disadvantage from other lockers from the basic Padlocks to a fingerprint scanner without using any keys. It has user friendly interface for easy access on the system.

1. The designed Pc –based locker provided an easy access for the user’s by using biometric technology as fingerprint as the main key access.

2. It provided secure storage of personal belongings by installing in the permanent lock and alarms for each cabinet.

Recommendations

For further improvements of the proposed design, the following are recommended:

1. Future researchers should provide a back up power supply which can provide a longer period of voltage or a generator.

2. They should provide other preferences for replacing other system devices to lessen the power consumption of the circuit.

3. They should provide higher specifications of personal computer for faster processing of the database.

EXPT.NO.3: INDUCTOR CHARACTIRISTIC AND TESTING

OBJECTIVE:

· To test an out circuit diode with an analog multitester.
· To test an in circuit zener diode with an analog multitester.
· To verify the volt ampere characteristic of zener diode.

REQUIRED SKILLS:

Knowledge in the proper use of multitester and familiar with the use of analog trainer (ATL-01 or equiv.) and breadboading components.

MATERIALS REQUIRED:

PROCEDURE:

Part 1: Out circuit testing of a zener diode

Test the supplied zener diode with an analog multitester following the same technique used in testing an ordinary rectifier diode as in part 1 of EXPT. NO. 15. Record the measured forward and reverse voltage current and resistance as indicated by the LV, LI and Ω scales respectively, in Table-19.1 under their respective columns.

Part 1: In circuit testing of a zener diode

Construct the circuit as shown in fig.19.1 and then, test the zener diode without disconnecting by using the same analog multitester and procedure as in step #1. Record the results in Table 19.2 under their respective columns.

Part 1: Anode to cathode volt ampere characteristic of a zener diode

Set the dc voltage regulator output to 10v and then, construct the circuit as shown in Fig. 19.2 with the voltage at V1 initially adjusted to zero volt.
Adjust the potentiometer slowly to set the voltage V1 to different levels specified in Table 19.3. Measure the anode to cathode voltage and current of the diode for each setting and record the results in the same table under their respective rows and column.
