Explanation
A digital watermark is a hidden signal embedded in a data file that can be used to identify the owner, source, or authenticity of the data. A watermark is difficult to detect and remove without degrading the quality of the data. However, one way that a watermark might still be inadvertently removed is by truncating parts of the data, such as cropping an image or cutting a video. This might affect the location or size of the watermark and make it unreadable or invalid.
