Abstract: A method for preventing tampering with the accessibility of resources specified by Universal Resource Locators (URLs) comprising establishing a tamper-proof channel between a client and a proxy; requesting URL content via the tamper-proof channel; forwarding URL requests from the proxy; and returning responses to the client via the tamper-proof channel.

Abstract: A method and associated system removes identifiable attributes from displayed advertising content, and instead locates these attributes within the isolated memory area that is accessible only the embedded Javascript™. Steps are taken to ensure that the displayed advertising content is correctly formatted, and Javascript™ routines are used to emulate the normal interactive functionality of the ad. Because the identifiable attributes of the ad content are now located in the isolated world of the embedded Javascript™, it is not possible for a web browser plugin executing in isolated world to access them. In this way, it becomes impossible for an ad blocking tool to automatically identify and remove such advertising content.
