Abstract Geometric malicious attacks happen the damage the original video content and hence to protect the video content, the GMSAT algorithms are developed. These algorithms make the watermark extraction not to work which will hinder copyrights. We in this work study the geometric attacks that happen by cropping the video frames.

Geometric malicious attacks happen the damage the original video content and hence to protect the video content, the GMSAT algorithms are developed. These algorithms make the watermark extraction not to work which will hinder copyrights. We in this work study the geometric attacks that happen by cropping the video frames. During experimentation we found that the algorithm shown good results which can be used to protect the video content in the online medium. Read More Read Less

Abstract Many attacks aim at the with the intention of damaging the critical infrastructures. These attacks can be handled in wireless environments with new communication devices. Early identification is possible when proper design and structure of the network is used. We in this paper have discussed how the wireless sensor networks can enable to manage the attacks and manage the protection....

Abstract Wireless communication if properly employed with the use of electronic devices can ensure reliable and effective communication. In such communication the people should ensure good security. We did perform the lab analysis on the aspects of Wi-Fi IEEE 802.11a 54 Mbps open links. This study did evaluation of the technology with the proper equipment. We have presented the results with... Wireless communication if properly employed with the use of electronic devices can ensure reliable and effective communication. In such communication the people should ensure good security. We did perform the lab analysis on the aspects of Wi-Fi IEEE 802.11a 54 Mbps open links. This study did evaluation of the technology with the proper equipment. We have presented the results with ISO level 4 from TCP experiments. TCP throughput is measured versus TCP packet length. Jitter and percentage datagram loss are measured versus UDP datagram size. Results are compared for both point-to- point and four-node point-to-multipoint links. Finally, we have made the inferences based on the link performance with extensive results. Read More Read Less
