Security has recently become one of the most significant and challenging issues for the diffusion of new information technologies. Since digital data can be easily copied, multiplied without loss of information, and manipulated without detection, are there a need for security solutions that address these threats? Security solutions are particularly attractive for industries such as distributed manufacturing processes and e-commerce, as their manufacturers only provide access control mechanisms to prevent misuse and theft of material. In all these aspects, multimedia systems are the ones that play an important role in the process of sending, retrieving and transferring data through different multimedia devices. So the purpose of intelligent media security services was born to monitor which problem actually persists and what measures need to be taken to minimize it. Intelligent multimedia surveillance involves the analysis of multiple sensing inputs including video and audio streams, radio frequency identification (RFID), and depth data. This data is processed for the automated detection and tracking of people, vehicles and other objects. The goal is to identify moving targets, understand their behavior and detect suspicious or anomalous activity for crime prevention. Despite its advantages, there is some social apprehension regarding the use of such technology, so an important challenge in this research area is to balance public safety and privacy in multimedia systems.
