Abstract
Watermarks may be used to deter certain types of information leaks. In one example, leaks occur in the form of posting, in public forums, screen shots of private pages. To deter this example kind of leak, private web pages within an organization may be watermarked with an experience identifier that identifies the session in which the screen shot is captured. Other information may also be included in the watermark. The watermark may be designed to survive image compression, so that it can be recovered from either a compressed or uncompressed image of the web page. By using an experience identifier recovered from the watermark, and logs that describe activity associated with that experience identifier, it may be possible to identify the source of the information leak.
