facial recognition biometric and passcode access control system

Facial recognition biometric and password refers to two types of authentication methods often used together or separately for secure access to devices, apps, or physical spaces (like smart locks or phones). Here's a breakdown:

1. Facial Recognition Biometric

Facial recognition is a biometric authentication method that uses a camera and AI algorithms to analyze a person’s face and confirm their identity.

How It Works:

3D or 2D scanning captures facial features (e.g., distance between eyes, jawline, cheekbones).

Compared to stored data (face template).

If matched, access is granted.

Pros:

Fast and hands-free.

Harder  if using 3D or infrared scanning (vs. just a photo).

Can work in low-light with infrared.

 Cons:

Privacy concerns (camera always on in some cases).

Can be less reliable if lighting is poor or face is partially covered.

Cheap systems using 2D cameras can be fooled with photos.

???? 2. Password / PIN

This is a knowledge-based authentication method. You must input a numeric or alphanumeric code to gain access.
