Facebook is to step back from the use of facial recognition software to identify faces in photographs and videos.
Concerns about privacy, racial bias, and accuracy have raised ethical issues about the use of the software, which is widespread in China.
Regulators had not yet provided a clear set of rules over how it should be used, Facebook said in a statement.
Facebook users had an ‘opt-in’ option to allow the feature to scan their face and issue a notification if a picture of them was posted.
Jerome Pesenti, vice president of artificial intelligence at the firm wrote in a blog post: "Amid this ongoing uncertainty, we believe that limiting the use of facial recognition to a narrow set of use cases is appropriate."
