Not only has face search technology advanced rapidly, but it continues to develop quickly today. Facial recognition software has become the state of the art, and social media and tech are in love with it. Even Social media giants, like Facebook, are using it now.
According to Facebook, we can now use face recognition to find photos we are in posted by other people. However, not everyone who uses Facebook is happy about this new option. Like most young tech, it has its share of distrust.
Facebook and Face Search
Facebook tells you all about their face search for images when you log-on after you have logged out after a while. They have the setting turned on already for you but explain to you how to turn it off if you don’t want to use the new facial search feature. (If you are wondering how to turn off Facebook’s facial recognition, we have a video below.)
Although Facebook has rolled this software out for users of the giant social network, according to USA Today, three Illinois residents are suing the popular social media site because of face search. They are suing them under the Biometric Information Privacy Act. This state law is one of only two in the entire nation that regulates facial recognition technology. A California judge has officially ruled that this case can move forward. Because of this, Mark Zuckerberg, the founder of Facebook, is facing billions of dollars in damages if these residents win this significant case.
What is Facial Recognition?
What is facial recognition, or face search, exactly? Face recognition is a technology software used to identify a person by the features of their face. Whoever is using the software records the facial features of the people who will be using face search to access or get into a place or site. Once their facial features are documented, the software will recognize who they are, from that point forward. This way, they can sign-in to different places and websites, using their face. The software remembers their features and from that point forward, will know who they are.
Facebook is using this software for people to find photos they are tagged in whether they did the tagging themselves or someone else did. Although they have rolled this feature out in the United States, users do have a choice whether they want to use this feature or not. Meaning, they have the option to leave it on, since it comes turned on already for users, or they can go into their settings and turn it off. This is proof that Facebook is not forcing the use of this software on anyone.
How Face Search Works
So, maybe you are wondering how face search works? This brand new tech software works by recording facial features. The input is in the form of either an image or a video, and the output is in the form of either identification or verification of the person’s face that shows in the picture or video. There are a few different ways facial recognition software is designed, and the main three include the following:
The computer detects the human face in digital images in this stage. Although you may be standing in front of a building or maybe even a tree, it will ignore what is behind you and only get your facial features. The computer will remember the elements of your face for the future.
The facial recognition process was invented in 1973. Since the invention of facial detection, there have been several of them. The year 2001 was a breakthrough year for face detection because Viola Jones invented the first type of face detection that detects in real time.
Alignment works by the computer dividing the face into visible landmarks. These visible landmarks are called nodal points, and they work by dividing different parts of the face for detection. Examples are the depth of the eye socket, the distance between each eye, and how full the nose is on a person’s face. Once determining the differences between these areas of the face, they would then be used to make a unique code. However, a problem occurred with this. The problem is that you can’t get the same view of your face twice. The reason for this is because our faces are in flux constantly. They are not like fingerprints. But there is a solution to this problem. Make a 3D face model and using the 3D that was made of the face to warp it to the frontal representation of it.
The real recognition of the face is classifying the identification from the aligned, detected, and usual faces for identification purposes. Recognition answers the “who is it?” question. However, it does consist of many different representations to identify the person. In plain English, it uses multiple identifiers to find out who the person is.
Where and How is Face Recognition Software Already Being Used?
There are many places and people who use facial recognition now. Keep reading to find out where and how it is used today.
Accessing personal devices
One place face search is used at is to unlock smartphones these days. Although most phones use a password, a pin number, or a fingerprint to open it, phones like the iPhone 8 are now using face recognition to unlock them. Another “personal device” being unlocked with face search are cars. The new cars coming out today have face search in them. This means they are aware of their surrounding environment. Thanks to the technology of today, we now have self-driving cars. How amazing is this?
Other places for face search
You probably already know that airports are using facial recognition for entering and departing the premises. However, other locations are also using face search. They are:
- In schools, confirming a student’s identity before and during after exams.
