. In this paper, we propose a grid-based approach as well as an algorithm to guarantee k-anonymity, a well-known privacy protection approach, in a location database. To do this, we assume that the service server will provide services but in a defined area and the grid will cover the area in which the service server takes effect, Then, the user's location will be hidden in an anonymization area. The anonymization area will be chosen by cells that forms a rectangle area so that this area contains at least k distinct users. |
