OLE-like principles are implemented using watermark data in digital objects
in order to effect object linking or embedding. In one embodiment, a
photocopier scans an original paper document to produce image data. This
image data is analyzed for the presence of watermark data identifying a
graphic on the document. With this watermark identifier, the photocopier
can query a remote image database for pristine image data corresponding to
the scanned graphic. This pristine data can be relayed from the remote
database to the photocopier and substituted into the scanned image data.
Output printed from the photocopier is thus based, at least in part, on
pristine image data, rather than on image data that has been subjected to
various corruption mechanisms (e.g., degradation of the original paper
document, artifacts due to scanning, etc.). A "photocopy" better than the
"original" can thereby be achieved.
