Guest editorial: Privacy-aware multimedia surveillance systems

摘要

Due to the significant increase in various security threats, safety has become a primary concern for our society. As a result, most of the public places such as airports, train stations, banks, shopping malls, subways and streets are nowadays equipped with state-of-the-art multimedia surveillance systems. These systems are meant to process sensory data to automatically detect suspicious or unusual behavior of people and alert security personnel so that preventive actions can be taken. Although such surveillance infrastructure has proved to be very useful from a security perspective; there has been apprehension among people in regard to their privacy safeguards. Citizens have increasingly begun to object to being watched electronically.
