DIGITAL VIDEO WATERMARKING ON CLOUD COMPUTING ENVIRONMENTS

Due to the need of rapidly distribute digital video, the use of digital watermarking to protect the digital copyright has become very crucial in the era of the Internet. Further, the process for video watermarking is very time consuming. For fast implementation of digital video watermarking, in this article we proposed the use of the Hadoop distributed computing system, where the original video is split, for the different requirements to realize watermarks embedding. The Hadoop distributed file system together with task decomposition are discussed, and the results obtained using the software MapReduce are analyzed. Both technologies are applied to the designed system and we found that the Hadoop distributed computing features play a key role in reducing the required computation time.
