Abstract
Methods and systems for invisible watermarking of images and video are disclosed. According to one embodiment, a method for watermarking video comprises selecting a block corresponding to a subset of pixels in a video frame. The block has quantized coefficients generated during encoding of the block. A modification function is applied to a candidate quantized coefficient (QC) in the block to incorporate a bit of a watermark message. The modification function is based on a set of configuration parameters.
