In one embodiment, a processing device receives, from an accessing system, an access request for stored information. In response, the device generates unique classification and tracking metadata based on the access request, and embeds the classification and tracking metadata as steganographic code into the source information before returning the information according to the request. The device then replies to the access request with the return information containing the embedded steganographic code.
