Taking advantage of the inter-layer prediction technique used in H.264/scalable video coding (H.264/SVC), in this paper we propose an efficient block-based encryption scheme (BBES) for encrypting H.264/SVC enhancement layers (ELs). BBES operates in three modes, namely, Intra-MB mode, Group-MB mode a...
