Fig. 2From: Street masking: a network-based geographic mask for easily protecting geoprivacyA graphic illustrating the street masking algorithm. Note that the top point is in a low-density area, the middle point is in a high-density area, and the bottom point is in a medium-density area. As a result, the top point is moved the furthest distance after masking, the middle point is moved the least distance, and the bottom point is moved a medium distanceBack to article page
