Biometrics is the analysis of an individual’s unique and behavioral characteristics to find his or her identity. The most commonly used technologies are face and fingerprint recognition, speech and voice recognition, gait and DNA matching. All these methods involve four steps: sample capture, feature extraction, template comparison, and matching. It is applied in different industries such as homeland security, health, airport, law enforcement, and education. Face recognition is the most adept biometric technology as it is unique, stable, and does not change over some time. However, certain challenges are experienced while using this technology. This paper reviews different literature sources that cover ways of mitigating the risks in using face recognition devices. These risks include False Reject Rates (FRR).

Introduction

Biometrics has emerged as one of the most effective ways to enhance identification processes through unique human characteristics, which can be either physical or behavioral. With technological advancements, biometric systems have integrated into various sectors such as security, aviation, healthcare, and law enforcement, providing methods to verify an individual's identity accurately.

Despite the promising applications of biometric technologies, specifically face recognition, there are significant challenges, particularly concerning accuracy and user acceptance. One critical issue is the occurrence of False Reject Rates (FRR), where legitimate users are incorrectly denied access. This paper discusses methods to mitigate such risks, focusing on the factors contributing to FRR and proposing solutions.

Understanding False Reject Rates

False Reject Rates are prevalent in biometric systems, especially those relying on facial recognition technology. FRR occurs when a system fails to authenticate a legitimate user, attributing such failure to multiple factors. Factors influencing FRR may include environmental conditions, the quality of the training data, and the specific algorithms implemented in the system.

Research indicates that one of the significant causes of FRR is the reliance on outdated or biased training datasets, which may not represent the current population's diversity (Yeung et al., 2020). When systems are developed using such data, the likelihood of errors in representing various demographic groups increases, leading to higher FRR.

Mitigating False Reject Rates

To address the high FRR in face recognition technology, several strategies can be employed:

  • Improving Training Data: Utilizing diverse and current datasets during the training phase of the biometric systems significantly enhances their performance in real-world applications. Ensuring that the training data comprehensively represents different demographics, including ethnicity, age, and gender, can lead to a substantial reduction in FRR (Gates, 2011).

  • Algorithm Enhancements: Continuous advancement in algorithms and technologies used for feature extraction can also lower FRR. Addressing issues such as occlusion and varying environmental conditions can create more robust biometric systems.

  • User Feedback and Adaptability: Incorporating user feedback to adapt systems dynamically can help mitigate the psychological impacts of FRR. Ensuring users understand the limitations of technology and providing feedback mechanism can aid in improving user experience.

  • Privacy Measures: Implementing stringent privacy policies can also reduce the anxiety associated with biometric systems usage. Clear indications of how biometric data is stored and used can cultivate trust among users (Pato et al., 2010).

Conclusion

While biometrics, particularly face recognition, promise enhanced security and identification methods, the challenges posed by False Reject Rates necessitate urgent investigation and intervention. By improving the accuracy of the systems through better data practices, algorithmic updates, and user engagement, the reliability of biometric identification can significantly improve. The goal is to ensure that legitimate users experience minimal frustration caused by technology, thereby enhancing overall productivity and satisfaction.
