Browser Document Usage Tracking via Plug-in Mediator

The patent introduces a document viewer plugin as an intermediary component that bridges the gap between the browser environment and document processing applications. The plugin is registered with the browser to handle specific document types (e.g., PDF) and enables cookie tracking within the document viewing context, allowing conventional Internet cookies to track user behavior both on webpages and within documents accessed through the browser.

The document viewer plugin performs self-registration with the browser, automatically configuring itself to handle specific document types. When a user accesses a document through the browser, the plugin activates and begins tracking user interactions (such as reading time, scrolling, highlighting) without requiring additional manual setup. The plugin serves itself by managing its own integration with the browser and document processing application, enabling seamless tracking of user behavior within the document viewing context.
