A method and system for selecting and modifying a geofence is provided. The method includes registering a physical object with geofence policies of a user. The physical object is tagged with a digital tag comprising information associated with the user respect and geofence policies. Input data indicating a value, an emotional attachment, and a sentiment of the physical object with respect to the t user is received and the physical object is detected via sensors. Reactions of the user with respect to additional physical objects located within a specified geographical boundary surrounding the first user are detected and a resulting classification for the physical object is generated. A geofence policy is selected and it is detected that the physical object has been removed from a geofence for a specified time period threshold. A resulting action associated with detecting that the physical object has been removed from the geofence is executed.
