Facebook launched facial recognition technology to automatically identify people in photo. It was previously launched for North American users last year.
If you or a friend upload a photo that looks like you, Facebook may suggest tagging you in the new photo. This helps your friends label and share their photos, and makes it easier to find out when photos of you are posted.
This feature uses a comparison of photos you’re tagged in to suggest that friends tag you in new photos.
If someone you’re not friends with uploads a photo of you, your name won’t be suggested to that person. Also, if you upload photos of people you’re not friends with, Facebook won’t suggest their names to you.
By default “Suggest photos of me to friends” is enabled in your facebook account. You can opt out of this feature on the Privacy Settings page. Click Customize settings and use the control labeled, “Suggest photos of me to friends.” Note: If you disable this feature, friends can still manually tag you in photos.
Disable “Suggest photos of me to friends”
- [advt]Go to your Facebook account’s privacy settings.
- Click on “Customise settings”.
- Under “Things others share” you should see an option titled “Suggest photos of me to friends. When photos look like me, suggest my name”.
- Unfortunately at this point you can’t tell whether Facebook has enabled the setting or not, you have to dig deeper..
- Click on “Edit settings”.

- Change it to “Disabled” if you don’t want Facebook to work that way.

You’re always in control of your tags on Facebook:
- Only friends can tag you in photos
- Facebook will notify you when a friend has tagged you
- You can remove a friend’s tag at any time
- Tag suggestions are based only on photos you’ve allowed yourself to be tagged in
How it Works?
Two types of information are required to automatically suggest that a newly uploaded photo looks like someone who’s been tagged on Facebook before:
- Information about photos you’re tagged in — When you’re tagged in a photo, Facebook associate the tags with your account, compare what these tagged photos have in common and store a summary of this comparison. If you’ve never been tagged in a photo on Facebook or have untagged yourself in all photos of you on Facebook, then this summary information hasn’t been created or stored for you.
- Comparing your new photos to stored info about photos you’re tagged in — When you or your friends upload photos, they may be compared automatically to the summary information Facebook have stored about what your tagged photos have in common. The results of this comparison may also be used to group photos or suggest that photos look like you. You and your friends always have the option to ignore these suggestions. Facebook only associate the photo with you if your friend saves these suggestions. If friends do tag you, you’ll be notified automatically and can untag yourself if you don’t like the photo or don’t want to be tagged.[source]
