Also, the position of the important area detected before or after the important area is scrambled can be maintained to be consistent without having to use a metadata file. In addition, a scrambling algorithm of the same key value can be applicable regardless of the size of the important area. As a result, the system efficiency can be enhanced by effectively protecting personal information compared with a CCTV-based video security system. | 06-23-2011 |
