Head mounted displaysbring eye tracking into daily use and this raises privacy concerns for users . Privacy-preservation techniques such as differential privacy mechanisms are recently applied to the eye tracking data obtained from such displays ; however, standard differential privacy mechanisms  are vulnerable to temporal correlations in the eye movement features.
