| Abstract(in English) | Partial video scrambling techniques which don't encrypt but degrade video contents have been proposed in order to use the scrambled video as the sample video in paid video delivery services. Deliverers can make scrambled videos which have degrading degree needed by controlling the scrambling strength. In this study, we proposed a partial video scrambling technique by changing the values of motion vectors of MPEG and evaluated the degrading degree and concealing degree of the scrambled videos. |
