Abstract
The present invention relates to postal metering devices and mail systems that variously employ digital watermarking techniques. In one implementation we provide on an envelope a marketing image in addition to postage indicia. The marketing image includes a digital watermark embedded therein. The watermark includes a link to access information that is associated with the envelope's sender. In some cases the digital watermark is fragile, allowing us to determine whether the marking image or postal indicia is authentic.
