Abstract:
1. One or more computer-readable storage devices that store executable instructions to apply a watermark to content, wherein the executable instructions, when executed by a computer, cause the computer to perform acts comprising: receiving, from a program, a request for a web page; retrieving, from said program, an experience identifier, wherein said experience identifier distinguishes an instantiation of said program from other instantiations of said program, a new distinct experience identifier being created for each instantiation of said program, said experience identifier remaining constant from a first time at which said program is opened until a second time at which said program is closed; applying a watermark to said web page to create a watermarked page, wherein said watermark comprises said experience identifier; entering, in a log, a fact that said web page has been requested under said experience identifier; providing said watermarked page to said program; recovering said watermark from an image of a page that was captured with said program; and analyzing said watermark in said recovered page to identify a user that captured said image, said identity of said user being determined using both said watermark and a log of web pages that were visited under said experience identifier.
