Abstract |
|
|
| In this paper, we propose a perceptual video encryption algorithm that utilizes rotation matrix and unit anti-diagonal matrix
to visually degrade video data with varying perceptibility. Blocks of pixels in video frames are identified and extracted using rotation
matrix and encrypted/decrypted using unit anti-diagonal matrix. Analysis of results show that the technique has low computational
overhead and ideal for on-the-fly encryption. When compared with existing techniques, the proposed method is better in the quality of
visual degradation, processing time and independent on the video format. Preliminary analysis also showed that the proposed method
can resist chosen/known-plaintext attacks. |
