  • Secure multi-principal web browser
    Patent number: 8250653
    Abstract: A web browser operating system using a browser kernel places principals having different origins in separate principal instances, where each separate principal instance executes in a separate protection domain. Principal origin may be determined using the combination of protocol, domain name, and port. The browser kernel mediates communications between principal instances, and between the principal instances and the operating system. Within each principal instance, a browser runtime executes as a restricted operating system process (ROSP), while any plugins are executed as a separate ROSP. Renderings from each browser runtime are combined by the browser kernel for presentation to a user.
