You can view it to confirm and tag yourself, ignore it, report it, or message the poster to have words about the photo.
These new additions expand on how Facebook already uses facial recognition, which is primarily through "tag suggestions" - a feature started in 2010 that suggests which of your friends should be tagged in photos that you upload to the site.
Candela went on to say that Facebook will respect the privacy setting people select when posting a photo, meaning "you won't receive a notification if you're not in the audience". The new tool will notify you when you appear in media and allow you to decide if you want to tag yourself, remain untagged or even reach out to the person that posted the photo or video with any concerns you may have. The good news is that you can turn the feature off altogether with one simple setting.
The company also said it was adding facial recognition to its "automatic alt-text tool", which allows visually impaired people to hear an audio description of what is in an image on Facebook.
The new tools are the latest from Facebook as it tries to make the social network safer and more enjoyable for users.
Soon, the Facebook app will have an opt-in toggle for the facial recognition alert. When photos and videos are uploaded to our systems, we compare those images to the template.
Facebook will let you know when someone posts a photo of you - even if you aren't tagged in it.
Facebook is also planning to roll out a "simple on/off switch" to replace the settings for individual features that use face-recognition technology. The social network doesn't use facial-recognition technology in those regions, due to wariness from privacy regulators.
Introduced two years ago, the technology recognises broad object categories like "trees" or "river" and will now be able to read out the names of people in the photos too, provided they Facebook users. The post is titled: " Hard Questions: Should I Be Afraid of Face Recognition Technology? .
"We're doing this to prevent people from impersonating others on Facebook", Candela wrote.
Since 2010, face recognition technology has helped bring people closer together on Facebook.
