1. A computer implemented method of privacy masking video surveillance data, wherein the video surveillance data includes metadata associated with video data, the metadata describing objects or activity in the video data and including location data defining a location within a frame of the object or activity to which the metadata relates, comprising:
comparing the location data with privacy mask data defining a position of a privacy mask in the frame; and
based on the comparison, determining if the metadata is to be masked and masking the metadata if it is determined that the metadata is to be masked.
