Intelligent Video-Surveillance (IVS) systems are being more and more popular in security applications. The analysis and recognition of abnormal behaviours in a video sequence has gradually drawn the attention in the field of IVS, since it allows filtering out a large number of useless information, which guarantees the high efficiency in the security protection, and save a lot of human and mater...

In traditional intrusion detection systems (IDS) used for critical infrastructure protection, such as SCADA (Supervisory Control and Data Acquisition) systems, intrusion alerts are analyzed by human analysts (security analysts). They evaluate the alerts and take decisions accordingly. Nevertheless, this is an extremely difficult and time consuming task as the number of alerts generated could be...

This paper presents a novel method for data hiding based on neighborhood pixels information to calculate the number of bits that can be used for substitution and modified Least Significant Bits technique for data embedding. The modified solution is independent of the nature of the data to be hidden and gives correct results along with un-noticeable image degradation. The technique, to find the ...
