This paper presents four methods for selective video encryption based on the MPEG-2 video compression,including
the slices, the I-frames, the motion vectors, and the DCT coefficients. We use the AES encryption method for simulation
experiment for the four methods on VS2010 Platform, and compare the video effects and the processing speed of each
frame after the video encrypted. The encryption depth can be arbitrarily selected, and design the encryption depth by
using the double limit counting method, so the accuracy can be increased.
