INTRODUCTION
In today’s rapidly evolving technological landscape, organizations are seeking advanced solutions to enhance security
and optimize operations. The Al-Iman Workshop, a large-scale manufacturing facility, has faced challenges related
to managing access control and ensuring only authorized personnel enter the premises. Traditional access control
systems, such as ID cards and manual checks, are vulnerable to security breaches and often lead to inefficiencies.
Facial recognition technology has emerged as a promising biometric solution for secure and automated access control.
Unlike traditional systems, facial recognition offers the advantage of contactless authentication, making it more
hygienic and faster. This technology uses unique facial features to identify and verify individuals, ensuring that access
is granted only to authorized personnel. Despite its benefits, the adoption of facial recognition systems in workshop
environments presents various challenges, including the accuracy of the system, privacy concerns, and its integration
with existing security protocols.
This paper investigates the feasibility and effectiveness of implementing a facial recognition-based access control
system in Al-Iman Workshop. Specifically, the study aims to evaluate the system’s performance in terms of accuracy,
security, user convenience, and operational efficiency.
In recent years, the need for robust and efficient security systems in industrial settings has become increasingly
critical. Traditional methods of access control, such as ID cards, PINs, and manual checks, often suffer from various

limitations, including vulnerability to human error, time delays, and security breaches. These conventional methods,
while functional, are not as effective in high-security environments, where the need for precision and efficiency is
paramount. To address these challenges, many organizations are turning to biometric systems, which offer enhanced
security and streamlined access management. One of the most promising biometric technologies is facial recognition,
which leverages unique facial features for identity verification, providing a contactless and accurate solution to access
control.
Al-Iman Workshop, a manufacturing facility with a large workforce, faces ongoing challenges in managing secure
access to its premises. The existing access control systems were found to be slow and prone to errors, leading to
delays during shift changes and unauthorized access in certain high-security areas. As the workshop's operations
grew, it became clear that a more advanced, reliable, and efficient solution was required to safeguard the premises
and improve operational efficiency.
Facial recognition technology offers the potential to address these challenges by automating the access control
process, reducing human error, and improving overall security. By using this technology, Al-Iman Workshop aims
to eliminate the need for physical access cards or ID checks, which can be lost, stolen, or forgotten. The system can
authenticate employees quickly and accurately, even in environments with varying lighting conditions, without the
need for physical contact. This not only enhances security but also streamlines the entry process, saving time and
resources.
Despite the advantages, the implementation of facial recognition systems in industrial environments is not without
its challenges. Factors such as lighting conditions, the dynamic nature of workshop environments, and concerns about
employee privacy must be addressed to ensure the successful deployment of this technology. Additionally, while
facial recognition has become widely adopted in other sectors, its application in industrial settings remains relatively
new, making it essential to evaluate its effectiveness and identify areas for improvement.
This study examines the implementation of a facial recognition-based access control system at Al-Iman Workshop.
The goal is to assess the system's impact on security, efficiency, and user satisfaction within the workshop
environment. By evaluating the performance of the system and collecting feedback from users, the study aims to
provide valuable insights into the potential benefits and challenges of adopting biometric access control solutions in
industrial settings. The findings may also offer guidance for other organizations considering similar technological
upgrades to their security infrastructure.
METHODS
System Design and Implementation
The study involved the design, development, and installation of a facial recognition system at the Al-Iman Workshop.
The system was integrated with the workshop’s existing security infrastructure, including access gates and security
monitoring systems. The facial recognition software was selected based on its high accuracy rates, ease of integration,
and ability to function in different lighting conditions commonly found in industrial environments.
The system utilizes deep learning algorithms that analyze and compare facial features to an established database of
authorized employees. Each employee’s facial data was collected during an initial enrollment phase, where high-
quality images were captured and processed to create unique facial templates. The system was then configured to
grant or deny access based on real-time facial recognition.

DISCUSSION
The results indicate that the facial recognition-based access control system was highly effective in improving both
security and operational efficiency at Al-Iman Workshop. The system's high accuracy and speed in processing
authentication requests led to fewer delays and reduced the risk of unauthorized access. In addition, the reduction in
human error associated with manual access checks highlighted the reliability of the system.
Despite its advantages, the system also presented challenges, particularly in terms of user privacy concerns. While
the majority of employees expressed satisfaction with the system, a segment of the workforce raised issues regarding
the collection and storage of biometric data. It is essential to address these concerns by ensuring that the data is
encrypted, securely stored, and used only for authentication purposes.
Moreover, while facial recognition technology performed well in normal lighting conditions, some employees
experienced occasional issues with the system in low-light environments. Further adjustments to the system’s
algorithms and additional lighting improvements may be necessary to enhance performance under diverse
environmental conditions.
The implementation of the facial recognition-based access control system at Al-Iman Workshop provided valuable
insights into the potential advantages and challenges of using biometric technology in industrial environments. The
results of this study highlight how facial recognition can improve security, streamline access control processes, and
enhance operational efficiency. However, there are several key aspects of the system’s performance that require
further examination and consideration, including its effectiveness, user experience, privacy concerns, and
environmental factors that impact the system’s accuracy.
1. Security Enhancement
One of the primary goals of implementing facial recognition technology at Al-Iman Workshop was to enhance
security by providing a more reliable method of identifying authorized personnel. The system demonstrated high
accuracy, with an overall recognition rate of 98%. This is a significant improvement over the traditional access control
methods previously in use, which were prone to errors such as forgotten IDs, lost access cards, or even the risk of
unauthorized personnel gaining access using someone else’s credentials.
The system’s ability to accurately identify and grant access based on unique facial features reduced the risk of security
breaches significantly. Unauthorized access attempts were detected and flagged, with the system preventing over
98% of such instances. This performance aligns with existing literature on the effectiveness of facial recognition in
reducing unauthorized access in various settings, including airports and corporate offices (Zhang & Li, 2020).
However, it is important to note that no system is entirely foolproof, and the technology is not immune to potential
vulnerabilities. For instance, there could be challenges related to spoofing or system manipulation, though these are
often minimized by using advanced algorithms and integrating multi-factor authentication when required. The results
from the study indicate that such concerns are minimal when the system is properly configured and maintained.
2. Operational Efficiency
Another major advantage of the facial recognition system was its ability to streamline the access process, making it
faster and more efficient. The average authentication time for facial recognition was recorded at 1.2 seconds, a marked
improvement over the previous manual system, where each ID card check took approximately 5 seconds. This
reduction in authentication time contributed to a smoother entry process for employees, particularly during peak
hours when multiple staff members were entering or exiting the workshop.
Additionally, the system eliminated the need for physical ID cards, which could be misplaced or forgotten. Employees
no longer had to carry or swipe physical cards, and the entire process became more seamless. For large workshops
like Al-Iman, where multiple shifts occur daily, these time savings can significantly reduce bottlenecks and ensure
smoother transitions between shifts. Furthermore, this reduction in physical interactions is especially beneficial in
maintaining hygiene and reducing the risk of spreading diseases, as it allows for a touchless authentication process.
Despite these efficiencies, there were occasional instances where the system faced delays due to environmental
factors such as poor lighting or obstructed views. These issues were relatively infrequent, but they highlight the
importance of optimizing the system’s configuration to adapt to different environmental conditions, which we will
discuss further.

3. User Experience and Satisfaction
The overall user experience with the facial recognition system was overwhelmingly positive. Survey results indicated
that 85% of employees found the system easy to use, and many expressed satisfaction with the system's convenience.
Users appreciated the speed of the authentication process and the fact that they no longer had to rely on physical cards
or remember PINs.
However, some employees raised concerns regarding privacy. Although the system's implementation was intended
to be a secure and efficient means of access control, several users expressed unease about the storage and handling
of their biometric data. These concerns are not unique to Al-Iman Workshop but are common when adopting
biometric technologies. It is critical to address these concerns by ensuring transparency in how the data is collected,
processed, and stored. Employees must be assured that their facial data is securely encrypted and used solely for
access purposes, as well as comply with relevant data protection regulations.
Providing clear communication and policy guidelines regarding data privacy is essential for gaining employee trust.
Additionally, ensuring that biometric data is stored securely and not shared with third parties can help alleviate
concerns. Workshops and other organizations considering similar systems must be proactive in establishing robust
data security policies and providing transparency to their workforce.
4. Environmental and Technical Challenges
One of the main challenges identified during the study was the system’s performance in environments with varying
lighting conditions. Although the facial recognition system was designed to function in a variety of lighting settings,
it did experience occasional difficulties when there was insufficient lighting or when faces were partially obscured
by personal protective equipment (PPE), such as face masks. This is a common limitation in facial recognition
systems, as they rely on clear, unobstructed views of facial features to accurately match them to the database.
To address this, the workshop could invest in additional lighting enhancements in critical access areas or use more
advanced facial recognition algorithms capable of compensating for low-light conditions. In addition, facial
recognition systems could be integrated with other forms of authentication, such as card readers or PIN-based
verification, to ensure access is not hindered in challenging conditions.
Another environmental consideration is the potential for system errors due to environmental factors such as dust, fog,
or humidity. In industrial settings like Al-Iman Workshop, where equipment and materials are constantly in motion,
such factors could impact the accuracy and functionality of the system. Regular maintenance and calibration of the
cameras and software will be essential to ensuring the system operates reliably in all conditions.
5. Scalability and Future Applications
The success of the facial recognition-based access control system at Al-Iman Workshop suggests that similar systems
could be successfully deployed in other industrial environments with a high volume of employees and a need for
efficient security measures. The system’s scalability is one of its key advantages, as it can easily accommodate a
growing workforce or be extended to other areas of the workshop or additional facilities.
In the future, the system could be expanded to include additional features, such as integration with time and
attendance systems for better workforce management or the addition of multi-factor authentication to further enhance
security. The flexibility of facial recognition technology also allows it to be adapted to meet specific organizational
needs, such as restricting access to certain areas or tracking employee movements within the facility.
CONCLUSION
The implementation of a facial recognition-based access control system at Al-Iman Workshop was a success in terms
of enhancing security, reducing human error, and improving operational efficiency. The system demonstrated high
accuracy, fast processing times, and a significant reduction in unauthorized access. However, addressing privacy
concerns and optimizing the system’s performance in challenging lighting conditions are areas that require attention
for future enhancements.
This case study demonstrates the potential benefits of biometric systems, specifically facial recognition, in industrial
settings. The successful integration of such systems could serve as a model for other workshops and industrial
facilities seeking to improve access control, streamline operations, and enhance security.
