Facial recognition systems are traine using Facial recognition your online pictures. These AI systems are far more powerful than dualists like  Facial recognition Orwell could have imagine in their worst nightmares. Fortunately, new tools can help you block .

Face Recognition

Since the Clearview scandal , everyone knows about the dangers of. But  systems can do much more than Buy Telemarketing Leads  just identify individuals through surveillance cameras. These AI systems are use in many applications today, some for surveillance. But others for the security of smartphones or door locks. So let’s take a look at

 

1. What is facial recognition?

Face recognition is a technology that can identify an individual by their face. Face recognition can be done by comparing the person to a photo of the person or to a database of photos of people.

 

Technically systems identify a person by determining and comparing facial features base on images. Because computerize involves the measurement of a person’s physiological features . Systems are classifie as biometrics, similar to iris or fingerprint recognition. Although  systems are less accurate as a biometric technology than the other two, they are widely adopte due to their ease of use, especially through camera surveillance.

systems have become customary in a short period of time, for example, to unlock smartphones, apps, and even doors. Law enforcement also uses to track people on watch lists. In China , facial recognition has been use for surveillance, and in the Unite States, it has also been use to track people active in protecte speech .

2. How does facial recognition work?

Automatic face recognition is a computer process that compares the features of a person’s face with one or more facial images store in a database.

The system uses computer algorithms to pick out unique details about a person’s face, such as the distance between the eyes or the shape of the chin. These details are then converte into a mathematical representation and compare to other face data collecte in adatabase. The data about a particular face is calle a face template, and it is different from a photo because it is designe to include only certain details that can be use to distinguish one face from another.

To find a match, the system

  1. Detect faces in images.
  2. Analyze detecte faces.
  3. Convert an image into a mathematical representation.
  4. Finally, this representation is matche with other people in the database.

This allows  to identify you as the true owner of an iPhone, or to open the front door of your home for you. For these use cases, doesn’t rely on a massive database of photos — it simply identifies and confirms a person as the owner of the device, while limiting access to everyone else.

Also, and this is how the Clearview scandal shows the potential dangers of  systems can use a database Sad Life Box of images, even images uploade to social meia, comparing them to images taken by special surveillance cameras to find people on a watch list. Said people are not necessarily criminals, and the authorities or companies that manage the watch list can define who should be on this list and who should be targete.

Some facial recognition systems are not designe to identify a person, but rather to calculate a probability score that represents how likely it is that an unknown person matches a specific face store in a database. Such systems typically list several potential matches, ranke by likelihood.
