The Hamburg Commissioner for Data Protection and Freedom of Information reopened proceedings against Facebook's facial recognition technology on Wednesday, the commissioner said.
"We stopped the investigation two months ago," said Johannes Caspar, the commissioner for Data Protection and Freedom of Information in Hamburg. The proceedings were stopped pending negotiations between Facebook and the Irish Commissioner for Data Protection, Facebook's supervisory authority in Europe, about the use of facial recognition.
Facebook uses facial recognition technology to suggest whom users should "tag" in photos.
The German data protection authority asked Facebook last Thursday what the outcomes of the negotiations with the Irish data protection commissioner were, Caspar said. While Facebook said it would refrain from creating facial profiles of new users for the moment, the company still stores data of existing users that was gathered without the users' explicit consent, Caspar said. Because Facebook still stores this data, further proceedings against Facebook are inevitable, the data protection watchdog said.
Facebook now has to decide if it wants to get the explicit consent of users, delete the data or face a lawsuit, said Caspar. The data protection authority will prepare a formal order to force Facebook to delete the data or to ask users' permission, he added. This order could be finished at the end of August or at the beginning of September since the case against Facebook was already fully prepared in June and not much has changed since then, Caspar said.
If Facebook refuses to comply with the data protection requirements, the data protection authority will file a lawsuit with the Administrative Court of Hamburg, Caspar said. Facebook is, however, welcome to inform the authority of an acceptable method for obtaining consent by concerned users or to confirm the deletion of the collected data at any time.
"We believe that the photo tag suggest feature on Facebook is fully compliant with EU data protection laws," a Facebook spokeswoman said in an email.
