A method, apparatus, and computer program product are provided for anonymizing a trajectory. Methods may include: receiving a sequence of probe data points defining a portion of a trajectory, each probe data point defining a location, where an origin includes a starting point of the trajectory and a destination includes an ending point of the trajectory; initiating a timer; in response to the timer reaching a predetermined time and the portion of the trajectory not including the origin or the destination, publishing the sequence of probe data points; and in response to the timer reaching a predetermined time and the portion of the trajectory including the destination and not the origin, generating a generalized destination of the trajectory as a current geographic grid cell of the trajectory and publishing the generalized destination.
