Notes
- Biometric identification consists of determining the identity of a person. The aim is to capture an item of biometric data from this person. It can be a photo of their face, a record of their voice, or an image of their fingerprint.
- Here are some common examples of biometric security:
- Voice Recognition
- Fingerprint Scanning
- Facial Recognition
- Iris Recognition
- Heart-Rate Sensors
- Iris scanning
- It is the process of using visible and near-infrared light to take a high-contrast photograph of a person’s iris.
- It is a form of biometric technology.
- Retinal scanning
- It maps the unique patterns of a person’s retina.
- The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting.
- It is highly accurate and difficult to spoof, in terms of identification.
- Voice recognition
- It is a computer software program with the ability to decode the human voice.
- It is used to operate a device or perform commands.
