Abstract

The modern information technology has provide great impact on information transfer and even if there are many network protocols supports video transfer the problem of information security has not been handled properly. Online video conferencing and live chat are the common applications of modern information technology but the quality of video being transferred or received is based on the frame rate. Also there are many situations where the content of video has to be authenticated before displayed to the user. To perform such authentication there are many approaches has been discussed earlier and suffers with the problem of malformed content display and accuracy. We propose a novel video authentication approach which is performed according to the network conditions. The method encodes the image in a selected block of the video frame, which will be used to decrypt the image. The water marking is performed on the selected block only and with the identified hidden information the original image could be retrieved. The method also proposes a frame rate selection approach according to the network conditions and the same is used to choose the block where the watermarking could be performed. The proposed approach has produces efficient results in video authentication and data transfer.
