Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Presence information (PI) represents the updated status, context and willingness of communication partners in Voice over IP systems. For instance, the action that Alice switches her status (e.g., from ``idle" to ``busy") will trigger PI messages to notify her buddies this change. In a centralized presence service system, presence communications are managed by a presence server based on users' buddylists. The privacy concern in this paper is that networking intermediaries, as adversaries, might be able to profile the buddy-relationship among the users by utilizing message arrival time.  found that the threat cannot be totally eliminated even if the server processes messages in batches. Attackers might observe the traffic in several rounds and thus profile the results. ,  introduce the attacks and discuss potential countermeasures.
