Know more about Facebook’s Face Recognition

Come on, people. Who does not know Facebook these days? I mean like seriously, users are of different ages and different continents. It’s one the biggest social media, folks. And here is the thing Face recognition feature is coming to the social network.

The feature was announced by Facebook in December.  It uses the same technology used to suggest friends you want to tag in photos and videos. The feature will help you find photos that you are not tagged in, or if there are users that attempting to use your picture as their own.

The users who opt-in for the feature of face recognition will be notified of the photos, even if they are not tagged on it as long as the settings of the photo privacy allow it.

You may have noticed the new notifications on the News Feed. Facebook has used other forms of facial recognition for years to suggest names of your friends when you tag photos.

There are feedback that say it is easier to manage face recognition in a simple setting.

How does the Face Recognition on Facebook works?

On Facebook, when you upload a photo the system detect and measure the faces. We have different measurements for the nose bridges, the eyelids and the width of lips. The combined measurements will become a face print. The face print will be used to identify the users.  When you upload a photo and the Facebook finds a match of the face prints of different users and it notifies you to tag a friend.

How to Turn-On the Face Recognition

The feature will not roll out to Facebook users in Canada and European Union because of the strict regulations on those regions about the collection of facial data. But, for other countries, go to Settings, there is a column Face Recognition click it then choose Yes.


How to Opt-Out of the Face Recognition Feature

The features are initially off to the users. If you turned it on, you can opt out whenever you want. The processed is the same as above. Choose No.


What does Opt Out mean?

The face templates are deleted when the feature is turned off, but it is not clear if Facebook still has the face print, or if Facebook still knows the untagged photos you appeared.

If you do not opt-in, the Facebook still has your face print and uses it in some parts of tagging process.

The Advantages of Face Recognition on Facebook

If you allow it on the settings, Facebook can automatically tag you in photos that you haven’t been tagged in. Facebook can notify you if another user uses your photo as their profile picture. In addition, visually impaired users can use the face recognition feature and social network’s automatic alt-text tool to identify the users who appear on the Facebook photos.

Facebook claims that the new feature will help reduce the misuse of photos of users. Especially, in cases of cyber criminals and the malicious users impersonating other users using other photos.

The Disadvantages

Facebook changes its features regularly. Facebook has 2 billion users worldwide. And Facebook features are carried forward to other platforms that are also owned by Facebook, Instagram, and WhatsApp.

Even though the technology respects the privacy settings of the post set by the user, users can still be connected to other users. For example, if you upload a photo that accidentally captures a random stranger, that person may get notified and strangers could send unwanted friend requests. This may result in not intended breach of privacy for the user who uploaded the photo and the user who was notified about the tag.
