SYSTEM AND METHOD FOR EFFICIENT PRIVACY PROTECTION FOR SECURITY MONITORING

A new approach is proposed to support efficient user privacy protection for security monitoring. A set of stick figures depicting a human body of a user is extracted from a set of still images taken over a period of time in a collected video stream at a monitored location. An activity of the user at the monitored location is then recognized based on analysis of the one or more stick figures in each of the one or more still images taken from the video stream over the period of time. In some embodiments, at least a portion of the human body of the user is pixelized to ensure protection of the user's privacy data while still enabling the security monitoring system to effectively perform its security monitoring functions. Additionally, the captured privacy data of the user is securely stored at a local site to further ensure privacy of the user.
