Abstract: An approach is provided for protecting a user identity in communication based on privacy information. The privacy engine selects one or more parameters associated with a privacy metric. Next, the privacy engine determines the parameters in a communication environment, the communication environment including a user device and a plurality of other devices. Next, the privacy engine computes a privacy level based, at least in part, on the parameters and the privacy metric. Next, the privacy engine compares the computed privacy level against a predetermined privacy level. Then, the privacy engine triggers a communication to one or more of the other devices in the communication environment based, at least in part, on the comparison.

Abstract: The aim of the present invention is to provide a method to detect misbehavior use of the IEEE 802.11 standard without modifying the standard itself. This aim is reached according to a method for detecting misbehavior in a contention based communication network, this method comprising the steps of: recording at least some of invalid frames with their respective station identification issued by the stations accessing an Access Point, recording at least some of valid frames with their respective station identification issued by the stations accessing the Access Point, determining, for each station, a scrambled ratio based on the number of invalid frames and the number of valid frames, detecting a misbehavior station based on a station which has a substantially lower ratio than the other stations.
