Why does Facebook want to recognize our faces?

June 18, 2012. Facebook acquires a company located in Tel Aviv, called Face.com, which had developed a facial recognition platform to identify images on the web and mobile applications. The Israeli company was able to label, before being acquired by the Social Network of Zuckerberg, more than 18,000 million faces.



Almost at the same time as Face.com, Facebook buys FacioMetrics, which developed a system that applies advances in artificial intelligence (AI) to analyze face images in mobile applications, and even in the identification of the emotions they convey . With the FacioMetrics software you can know if the user is sad or happy when taking a photograph and analyzing the different parameters of the human face.

FacioMetrics was created within Carnegie Mellon University, and developed artificial vision and machine learning algorithms capable of detecting seven different emotions on people's faces through their photos.

With these two acquisitions, Face.com and FacioMetrics, and some more like Masquerade, Facebook develops DeepFace, a facial recognition system combined with deep learning or deep learning. With DeepFace, which uses a 9-layer neural network and 120 million connections, Facebook is able to identify human faces in digital images. The system has 97% accuracy, compared to 85% of the image recognition system used by the FBI.

DeepFace not only connects a person's face with their name, but can literally find a needle in a haystack and find a face in an image that contains thousands of different faces. According to experts, the human brain is only 28 percent more accurate than the facial recognition program developed by Facebook from the companies it acquired.

Facebook is far from being the only company that has ventured to recognize its users with facial recognition. So do Apple, Google, Samsung. Microsoft or Huawei, for example. And what you have to ask yourself is what is the true purpose of requiring users to accept and authorize the recognition of their faces.

Facebook has already faced resistance to DeepFace. In Europe it was forbidden, but since mid-April users of the Social Network are asked if they want to authorize facial recognition when they open their feed. And from here arise the questions of the users, when the scandal of Cambridge Analytica is still very recent that has taken Zuckerberg to the United States Congress to give explanations about the cession of data of millions of clients to third companies.

Where are the data of the faces recognized by DeepFace stored? Who can access them? What does Facebook do with its clients' images? Does facial recognition work only when Facebook is open or also when other applications are open? Could facial recognition be used to identify someone who participates in a legal protest? Surely Facebook is able to answer them and reassure their customers, if they are not.

What is cherophobia?

The querophobia is the irrational fear of being happy. The term comes from the Greek word "chero", which means "to rejoice".

When a person experiences cherophobia, they are often afraid to participate in activities that many would describe as fun or that give a sense of happiness. The truth is that it has not yet been investigated or clearly defined, as this disorder is not yet contemplated in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose mental health conditions.



What are the symptoms of cherophobia?

Some experts classify the querophobia as a form of anxiety disorder. In this case, anxiety is related to participation in activities that make us happy.

Is a person with cherophobia always sad? No way. Only avoid activities that can lead to happiness or joy, for example a party, a concert or a meal of friends. The person with kerophobia rejects all those opportunities that could lead to positive changes in life due to the fear that something bad will happen. If someone sounds funny, he will get away from it.

Some of the key thoughts that a person with cherophobia may have include:

- Being happy will mean that something bad will happen to me (something good is followed by something bad)
- Happiness makes you a bad person or a worse person.
- Showing that you are happy is bad for you or your friends and family.
- Trying to be happy is a waste of time and effort.


What are the causes of cherophobia?

Sometimes, the querophobia may be due to the belief that if something very good happens to a person, or if their life is going well, it is also meant for something bad / bad to happen next. As a result, they may fear activities related to happiness because they believe that they can prevent something bad from happening. This is usually the case when someone has experienced a traumatic physical or emotional event in the past.

An introvert may also be more likely to experience this phobia, preferring activities alone or at most with two people at a time. They may feel intimidated or uncomfortable in group settings, noisy places and crowded spaces.

Perfectionists can also be associated with cherophobia. Those who are perfectionists may feel that happiness is a trait only of lazy or unproductive people. As a result, they avoid all that activity associated with happiness.



What are the treatments for cherophobia?

Because querophobia has not been extensively detailed or studied as a separate disorder, there are no FDA-approved medications or other definitive treatments to treat the condition. However, some suggested treatments include cognitive-behavioral therapy (CBT), relaxation strategies, such as deep breathing, daily or exercise, or exposure to events that cause happiness as a means to help a person identify that happiness does not have why have adverse effects in our life.
