Abstract
In this paper, we propose an encryption method to protect the region of interest (ROI) which is standard element in the scalable video coding (SVC). The proposed video encryption method provides secured SVC contents with the selective encryption scheme. In order to confine the encryption into the ROI, three encoding schemes are also proposed, which include the constrained motion estimation, exceptional handlings for the half-pel interpolation and Intra_BL mode in the boundary of a ROI. Experiments were performed to verify the proposed methods using the joint scalable video model (JSVM), and the experimental results showed that the proposed methods protect the ROI in SVC effectively .
