Implementation of Anti-Spoofing Methods in Face Recognition for Mobile-Based Employee Presence Applications

Introduction

In today's digital era, facial recognition technology has become increasingly popular, especially in mobile-based employee presence applications. However, the main challenge faced by these systems is security issues, particularly spoofing attacks that can deceive the system with fake data. Spoofing attacks are a significant threat to the reliability and security of facial recognition systems, as they can compromise the integrity of the system and lead to inaccurate results. Therefore, it is essential to apply effective anti-spoofing methods to ensure system reliability and prevent such attacks.

The Importance of Anti-Spoofing Methods

Anti-spoofing methods are designed to detect and prevent spoofing attacks, which can be launched using various techniques, such as print attacks, replay attacks, and deepfake attacks. These attacks can be launched using a variety of methods, including 2D prints, 3D masks, and even videos or images of the target individual. The use of anti-spoofing methods is crucial in ensuring the security and reliability of facial recognition systems, particularly in applications where accuracy and trust are paramount, such as employee presence systems.

Liveness Detection: A Key Anti-Spoofing Method

One effective anti-spoofing method is liveness detection, which examines signs of life, such as eye and lip movements, to ensure the authenticity of the face caught by the camera. Liveness detection is a critical component of anti-spoofing methods, as it helps to prevent spoofing attacks by verifying that the face presented is a real, living individual. This method is particularly effective in detecting and preventing spoofing attacks launched using 2D prints or 3D masks.

Development of a Face Recognition System with Anti-Spoofing Features

This study includes the development of a face recognition system equipped with anti-spoofing features, which are then tested for various types of spoofing attacks. The system is designed to detect and prevent spoofing attacks using a combination of liveness detection and other anti-spoofing methods. The system is tested using a variety of datasets, including the CASIA-FASD dataset, which is a widely used dataset for evaluating facial recognition systems.

Methodology

The methodology used in this study includes the development of optimized iFacenet models and the onnx model to detect attendance. The data used is divided into three sets: training, verification, and testing with a ratio of 8: 1: 1. The training data is used to train the model, while the verification data is used to evaluate the model's performance. The testing data is used to evaluate the model's performance in a real-world scenario.

Results

The results of this study show that the application of anti-spoofing methods significantly increases the security and reliability of the mobile-based employee presence system. Direct detection accuracy reached 94.72%, with a precision of 93.43% and recall 95.08% in the test data. Meanwhile, in the validation data, the model reached an accuracy of 89.77%, precision 88.96%, and recall 89.23%. These results demonstrate the effectiveness of the anti-spoofing method in detecting and preventing spoofing attacks.

Conclusion

Overall, this system is effective in detecting and counteracting spoofing attacks and can be applied in various contexts of use. Further development of this anti-spoofing method will not only increase the security of employee presence applications but can also contribute to the development of more reliable face recognition technology in the future. With the right steps, we can ensure that this technology is used effectively and safely for various purposes.

Future Work

Future work in this area includes the development of more advanced anti-spoofing methods, such as deep learning-based methods, which can detect and prevent spoofing attacks more effectively. Additionally, the development of more robust and secure facial recognition systems that can withstand various types of spoofing attacks is also essential. By continuing to develop and improve anti-spoofing methods, we can ensure that facial recognition technology is used safely and effectively in various applications.
