Abstract
In this research, a watermark algorithm is proposed to embed a secret
message in a digital video. The proposed algorithm exploits edges and corners
regions in images, to be hosts for hiding secret bits. Embedding in these regions
is consider optimal since these regions featuring with colors variation, so
embedding will not effect on uniform distribution of colors, and on transparency
requirement. The process of embedding and extracting watermarked massage is
implemented by decomposition digital video to several images (frames), then
selecting the edges and corners regions to be host locations, Least Significant
Bit (LSB) techniques are used to embed watermarked message in images of
digital video. Investigations results proved that number of hidden bits in corner
region is small in comparison with edges regions, but it is harder to detect. Text
message before embedded in video frames is encrypted by Advanced Encryption
Algorithm (AES) to increase security and robustness of watermarking process.
