How facial scanning equipment works
Before answering the question, let us first understand how the facial scanning device works
The process of facial scanning equipment realizing facial recognition through technology can be divided into the following steps:
- Facial image collection: The device uses a camera or sensor to collect the user’s facial image. These images can be still photos or live video streams.
- Facial feature extraction: The collected facial images are processed through image processing algorithms to extract facial feature points and feature descriptors. These feature points can include location, shape and texture information of facial contours, eyes, nose, mouth and other areas.
- Feature matching and comparison: Match and compare the extracted facial features with facial features pre-stored in the system. These pre-stored facial features can be the user’s registration information or a known facial database.
- Recognition and verification: Based on the results of matching and comparison, determine whether the collected facial image matches the pre-stored facial features. If the match is successful, the user authentication is confirmed to be successful; if the match fails, the user authentication is considered to have failed.
In the process of realizing facial recognition, facial scanning devices use a variety of advanced technologies:
- Computer vision: Use image processing and analysis algorithms to identify facial features, such as facial contours, eyes, nose, etc., and extract facial feature points and feature descriptors.
- Machine learning: Use machine learning algorithms to train and learn from a large number of facial images to improve the accuracy and robustness of facial recognition. For example, artificial neural networks or deep learning models are used to learn the representation and matching of facial features.
- 3D technology: By using technologies such as 3D sensors or structured light scanning, more accurate facial shape and geometric information can be obtained to improve the accuracy and stability of facial recognition.
- Liveness detection: In order to prevent facial recognition from being deceived, facial scanning equipment usually also applies liveness detection technology to determine whether the facial image comes from a real face. For example, detecting facial features by analyzing facial expressions, blinking, or performing eye tracking.
To sum up, the facial scanning device realizes the recognition and verification of the user’s face by collecting facial images, extracting facial features, matching and comparison, and recognition and verification, combined with technologies such as computer vision, machine learning, and live body detection.

Fairness and Bias of Facial Scanning Devices
Fairness and bias in facial scanning devices is an important topic of discussion. Here are some fairness and bias issues related to facial scanning devices:
Biased training data:
Training data sets for face scan device are critical to the accuracy and fairness of the algorithm. If there is bias in the training data set, such as insufficient coverage of certain groups of people or specific skin tones, the device’s recognition accuracy may be affected and result in higher misrecognition rates for certain groups of people. Therefore, device manufacturers need to ensure that training data sets are diverse and representative to reduce the presence of bias.
Diversity test samples:
Diversity of test samples is critical to evaluating device fairness. Test samples should cover factors such as different races, skin colors, genders, and ages to ensure that the equipment can perform well in identifying various groups of people. Relying solely on a single or limited test sample could lead to bias or misidentification of certain groups of people.
Influence of environmental factors:
The accuracy and fairness of facial scanning devices can be affected by environmental factors. For example, factors such as low-light environments, camera angles, and obstructions may cause the device’s recognition accuracy to decrease and create bias against specific groups of people. Equipment manufacturers and users should fully test and consider these environmental factors and ensure that the equipment can provide fair and accurate identification results in different environments.
Implicit bias:
Face scan device may be affected by implicit biases from their designers or developers. For example, when algorithms and models are designed, there may be preferences for certain features or facial structures, resulting in higher recognition accuracy for certain groups of people and lower accuracy for other groups of people. Device manufacturers should review and correct these implicit biases to ensure devices treat all populations fairly.
Misidentification and discrimination:
Facial scanning devices may have problems with misidentification and discrimination. Misidentification refers to incorrectly identifying one person as another person, while discrimination refers to the less accurate identification of certain groups of people. This may lead to a misidentification of a person’s identity or lead to prejudice and discrimination. Device manufacturers and users should take steps to reduce the risk of misidentification and discrimination and ensure that devices provide fair and accurate identification results for all types of people.
In summary, fairness and bias in facial scanning devices is a complex issue. HFSECURITY focuses on diversity and representation during the selection, training, and testing of data sets to reduce the presence of bias. At the same time, users and regulatory agencies should also pay attention to and evaluate the fairness of the device and ensure that it can provide accurate and fair identification results for all types of people.
