Abstract
Embodiments described include systems and methods for adding watermarks using an embedded browser. To provide protection to sensitive information from a network application rendered via an embedded browser of a client application, the client application can generate an overlay with a digital watermark, and apply the overlay over the embedded browser. The client application can selectively generate such overlays, and can customize the format of the digital watermark according to the information rendered on the embedded browser. The watermark can remain with any information that is imaged from the embedded browser, and provides a deterrent against misuse of the information via image capture from a computer screen for instance. By adjusting properties (e.g., contrast) of such an image, the watermark can be made visible and detectable, thus allowing such imaging activities and information to be tracked.
