Will watermark survive compression/quantization?

The simplest of the domains to insert digital watermark is the spatial domain, where the pixel value of the image is modified. Changing the pixel value does effect the image statistics. Due to the attribute of a watermark being imperceptible(in case of invisible watermark), there cannot be much devation from the original image statistics. In this situation, the watermark influence on each pixel must be atleast equal to one quantization step to survive. Similar arguments can be made for watermarks inserted in other domains. The general notion adopted is, if the photo watermarks are embedded in the same domain as the compression, then they have a higher probability of survival of such operations. (Ex. DCT domain for JPEG compression)
