II. LITERATURE REVIEW

Access control systems have become increasingly important in ensuring the security and convenience of various environments such as offices, educational institutions, and residential buildings. Traditional access control systems, such as key cards or passwords, have their limitations in terms of security and ease of use. This has led to the exploration of alternative solutions that incorporate advanced technologies such as artificial intelligence (AI) and automated door mechanisms.

Facial recognition technology has gained significant attention in recent years due to its ability to accurately identify individuals based on their facial features. Numerous studies have been conducted to develop and improve facial recognition algorithms. For example, in their research paper titled "Facial Recognition Algorithm Based on PCA and LDA," Li et al. (2019) proposed a face recognition algorithm that combines Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) to improve the accuracy and efficiency of facial recognition.

Additionally, automated door mechanisms have also been explored to enhance the convenience and efficiency of access control systems. Servo motors controlled by Arduino boards are commonly used to automate the opening and closing of doors. In their study titled "Design and Implementation of an Intelligent Access Control System Based on PLC and RFID Technology," Hu et al. (2020) developed an intelligent access control system that utilizes Programmable Logic Controller (PLC) and Radio Frequency Identification (RFID) technology for automated door operation.

(2021) proposed an integrated access control system that utilizes IoT and Firebase for data storage and management.

While facial recognition and automated door mechanisms have proven to provide enhanced security and convenience, there are challenges and limitations that need to be addressed. One of the major challenges is the vulnerability of facial recognition systems to photo-based attacks. These attacks involve presenting a photo of an authorized individual's face to gain unauthorized access. To mitigate this risk, an alert system can be implemented to notify administrators or security personnel in case of suspicious activities, such as photo-based attacks.

Xu et al. (2018) proposed a photo-based attack detection algorithm in their research paper titled "An effective and efficient photo-based attack detection algorithm for face recognition systems," which could be integrated into the access control system to enhance its security.

Real-time monitoring is another crucial aspect of access control systems, as it allows for immediate response to any security incidents or breaches. The use of live camera feeds and database updates provides administrators with real-time insights into entry and exit events. In their study titled "Design and Implementation of an Intelligent Building Access Control System Based on Edge Computing and Face Recognition," Zhang et al. (2020) developed an intelligent building access control system that utilizes edge computing and face recognition for real-time monitoring and response.

In conclusion, the Intelligent Access Control System with Automatic Door Operation project incorporates various technologies and concepts to provide a robust and intelligent access control solution. The combination of facial recognition technology, automated door mechanisms, Firebase integration, alert systems, and real-time monitoring offers enhanced security and convenience in accessing various environments.
