The social network is using photos you upload and names you tag to keep track of you, your friends and family.
A lawsuit in Illinois has brought this news to an otherwise unknowing population. The state has an old law that prohibits companies from using biometric data of its customers without permission.
Facebook has not denied using your photos to track you, but they have denied that the law applies to them.
Not many states have this biometric law. So again- be careful who you tag in your photos.
At least now we know who’s watching.
