N2 - It has been demonstrated in our earlier work [1] that partial video encryption can be effectively achieved by using alternative transforms. In this paper, we modify those floating-point based transforms to integer-based counterparts so as to be compatible with the H.264 standard. To this end, we present the design details of these integer-based transforms and their efficient implementations. To follow the H.264 standard that combines the transform and quantization processes, we present some special handling of the necessary scaling factors and the associated quantization. Finally, we demonstrate that the derived integer transforms can achieve partial video encryption with nearly the same performance as what has been achieved with floating-point transforms.
