Facial Recognition: Studies, Challenges and Prospects

Is facial recognition possible without the use of biometrics?

Understanding Facial Recognition

Facial recognition is a technology used to map, identify, or verify a person's facial structure. It is based on biometric techniques, artificial intelligence, 3D mapping and deep learning. By transforming the composition of the face into a unique geometric pattern, it allows for precise identification and authentication.

Key Technologies

Facial recognition is based on several fundamental technologies:

1. Computer Vision: Detects and analyzes faces in images or videos.
2. Feature Detection Algorithms: Identify specific points on the face (eyes, nose, mouth) to create a model.
3. Machine Learning: Trains models on datasets of faces to improve their ability to recognize.
4. Deep Learning: Uses deep neural networks to increase accuracy.
5. 3D Analysis: Captures the depth and contours of the face, increasing accuracy in a variety of conditions.
6. Biometric databases: Compare detected faces with databases to identify or verify a person.

How an Algorithm Works

1. Image capture: An image of the face is captured via a camera.
2. Face detection: The face is located in the image.
3. Face analysis: Facial features are recorded to create a digital representation.
4. Comparison with a database: The representation of the face is compared to the images in a database.
5. Decision: If a match is found, the person is identified, if not, access is denied.

Challenges of Facial Recognition

• Brightness variations and shooting angles
• Rotation and facial expressions
• Influencing factors such as age, clothing accessories
• Data security and ethical issues

Facial Recognition and Biometrics

Facial recognition is a subcategory of biometrics, focusing on the analysis of facial characteristics for identification and verification.

Towards Facial Recognition without Biometrics?

Factors such as data protection and regulations such as GDPR are driving the development of alternative methods, such as facial expression machine learning (FAA) and facial feature analysis (FAA). These technologies could reduce the risks associated with biometrics.

Benefits and Implications

The removal of biometrics in facial recognition could improve the protection of personal data, preventing intrusive surveillance and profiling. This would force the industry to adopt privacy-friendly technologies.

Work in Progress and Progress

Projects like Cambridge University's "Facial recognition in the wild" and Facebook's "DeepFace" are making rapid progress to improve the accuracy of facial recognition.

Leading Companies

Companies such as Facebook, Amazon, Google, Microsoft, and IDEMIA dominate the field with advanced algorithms and significant investments in R&D.
