Artistic caption of the security protocol (IMAGE) University of Copenhagen - Faculty of Science Caption Using the laws of quantum physics, the researchers developed a new security protocol that uses a person's geographical location to guarantee that they are communicating with the right person. Position-based quantum encryption, as it is called, can be used to ensure that a person is speaking with an actual bank representative when the bank calls and asks a customer to make changes to their account.
