A new move to secure Aadhaar, in which a randomly-generated 16-digit temporary number can be shared instead of the biometric ID, will be opposed in the Supreme Court by petitioners who are fighting a case against the system. "The new virtual ID is untested and unworkable. The UIDAI is trying to rectify technical breach by its untested technology," said a petitioner, adding, "In the hearing next week, we will oppose it tooth and nail."
