> The IJOP center also sends officials to investigate cases when an individual’s phone, ID card, or vehicle has gone “off-grid.” Screen 15 displays the prompt sent to officials requesting them to investigate a phone number that the system has lost track of. The officer is prompted to probe, using a drop-down menu, why the phone went off-grid. The officer is then asked to note whether the person questioned seems suspicious and whether the case needs further investigation.<p>> ...<p>> The IJOP system also alerts officials when people are using phones that do not belong to them, giving the officials information about the case and the personal particulars of the person who is registered to the phone account, such as their ID number (see screen 19). It is unclear how the system “knows” that a person is using a phone that does not belong to them.[80] Officials are again required to log the reasons for the mismatch and decide if the person is suspicious.[81]<p>This technique especially scary for people concerned about privacy, because it means passive attempts to avoid surveillance will invite more direct invasions.
