<p>The invention relates to a contactless privacy protection method which is intended to prevent or authorise a communication between a reader and an RFID label which are both located in an effective range. The invention is characterised in that it comprises: a) continuous detection for detection of a possible variation in an ambient magnetic field in one or more of the frequency bands assigned to the RFID labels; and b) upon detection of an instantaneous variation in the local magnetic field and in the absence of an inhibition, modification of a parameter value of a magnetic circuit such as to modify the instantaneous value of the local magnetic field.</p>
