Introduction

The increasing cases of theft of valuables have highlighted the need for effective security devices, one of which is a safe. However, the current safes often lack adequate security systems, making it essential to develop new ways to secure valuables. In this study, we designed a safe prototype equipped with an integrated security system that uses keypad, RFID (Radio Frequency Identification), and Fingerprint. The aim is to minimize the risk of theft that may occur in the safe.

Background

The use of safes has become a common practice to protect valuables from theft. However, the current safes often rely on a single security method, such as a combination lock or a key. This can be vulnerable to theft, especially if the combination or key is lost or stolen. Therefore, there is a need for a more secure and efficient security system that can provide multiple layers of protection.

Design of the Secure Security System

The safe prototype uses Arduino Nano microcontroller as the brain of the system, equipped with various supporting components such as keypad to enter access codes, RFID for identification through cards, fingerprint sensors for fingerprint introduction, solenoid to open the safe door, and LCD (liquid crystal display) to display the safe status information. The use of keypad and RFID as the main safety allows the safe owner to access it in a fast and practical way. However, in addition to the security layer, Fingerprint functions as an optional safety to deal with unexpected situations such as the loss of RFID cards or forget the access code.

Layered Safety Analysis

The layered security system in the safe design provides a significant advantage. By combining three different access methods, namely keypad, RFID, and fingerprints, this safe offers additional flexibility and protection. The use of RFID is very effective in situations where users have registered cards. In addition, the keypad allows users to have manual control in accessing a safe. However, fingerprints add a very personal security layer, because only the owner has access to their biometric data. This makes this system much safer compared to traditional systems that only rely on one type of access method.

How it Works

The system works as follows:

The user enters the access code using the keypad or uses the RFID card to identify themselves.
If the access code or RFID card is correct, the system will activate the solenoid, which automatically opens the safe door.
If the user has registered their fingerprint, they can use the fingerprint sensor to access the safe.
The system will display the safe status information on the LCD display.

Advantages of the System

The system has several advantages, including:

Multi-layered security: The system provides multiple layers of protection, making it more difficult for unauthorized individuals to access the safe.
Flexibility: The system allows users to access the safe using different methods, such as keypad, RFID, or fingerprint.
Personalization: The fingerprint sensor provides a personal security layer, making it more difficult for unauthorized individuals to access the safe.

Conclusion

With this Arduino Nano-based safe design, we can see the potential development of a better security system to protect valuables. This prototype not only provides a sense of security for the owner, but can also function as a basis for a more complex security system in the future. With the increasing need for better security, innovation in technology like this is very relevant and useful to prevent crime of theft that is increasingly troubling the community. The implementation of advanced technology in the security system provides new hopes for users in protecting their property in a more modern and efficient way.

Future Work

Future work can include:

Improving the security system: The system can be improved by adding more advanced security features, such as facial recognition or voice recognition.
Increasing the flexibility of the system: The system can be made more flexible by allowing users to access the safe using different methods, such as a mobile app or a voice assistant.
Reducing the cost of the system: The system can be made more affordable by using cheaper components or by reducing the complexity of the system.
