Did you ever wonder how you were able to unlock your phone by just looking at the camera? Or did you ever curious about how facial authentication systems work? The technology behind this is facial recognition or face recognition, which detects someone's identity by comparing his facial image to other images in a computer's database. Today, we will discover how this face recognition works and discuss its' effects in the era of anonymity.

The Beginning: Facial Detection

To begin with, facial recognition starts when a camera or a similar device takes a picture of a human alone or in a crowd. The first phase of facial recognition is pretty similar to one's ability to see. For instance, a child might see an unknown object and become curious about how that object works. Detecting a face was challenging at the beginning, but thanks to advancements in technology and the pioneers; Woody Bledsoe, Helen Chan Wolf, and Charles Bisson teaching a computer how to mathematically identify a face using various methods, the first step was taken.

The Resemblance: Analyzing the Face

In the second phase, these taken pictures are sent to a computer to be analyzed. During the analysis, the picture is divided into pixels - the smallest part of an image - and these pixels are then used to define unique facial parameters such as eye depth, the distance between eyes, forehead, chin and etc. This second phase of facial recognition is similar to a child asking his parents about an unknown object he discovered earlier.

The Matching: Finding the Match

In the third phase, these unique parameters are used in matching the face with its' possible owner. The database consisting of other known faces is compared until a good match is found for the taken picture. This vital step in facial recognition is similar to a parent thinking about what the object is before answering his child's question.

The Answer: Whom does this face belong?

Last but not least, when the processed picture gives a match from the database, the owner of that face can be easily found. Along with his name, if applicable, much more information, such as his phone number, current location, etc., can be found. Finding exactly who that person is can be really challenging since the databases consisting of other known faces are restricted to public use. This fourth step is familiar to the parent, explaining to his child what the unknown object is and the object's common usage areas.

Anonymity and Beyond for Face Recognition

Living in the era of facial recognition technologies, one might wonder about the consequences of the rapid use of these technologies. Making facial recognition technologies more affordable and scalable in terms of usage can lead to legal problems and is against the principles of the General Data Protection Regulation! There are several countries, such as China and the United States, that accuse people of being criminals based on a false positive result from a face recognition process. To elaborate, in the US, it is known that some states have purchased facial recognition systems that can scan public cameras live, and in China, where necessary, the police are running recognition technologies to identify persons of interest! These countries are taking precautions to stop it from happening and are starting to enforce new laws to restrict usage.
