Google patents browser sandbox to control ad data requests
This filing describes a method where a web browser runs specific code in a restricted, isolated area to create data requests for web pages. The browser sends a list of device details to a proxy server, which then decides whether to display content based on those details.
In the filing’s own words
Systems and methods described herein can provide a restricted environment for the local execution of server provided processor-executable instructions. The restricted environment can be maintained by a web browser to enable sandboxed generation of content requests by the web browser during the rendering of web pages. The restricted environment can enable the web browser to control the generation and transmission of content requests.
What exactly they claim (claim 1)
1. A method to exchange data in a networked system, comprising: storing, by a web browser executed by a client device, a client device profile comprising a plurality of client device parameters and processor-executable instructions to generate a content request in a restricted environment of the client device, wherein the restricted environment is associated with a content server; transmitting, by the web browser, a content item parameter to the restricted environment stored on the client device based on the web browser receiving a web page; generating, by the web browser executing the processor-executable instructions stored in the restricted environment, a parameter list based on the client device profile and the content item parameter; transmitting, by the web browser, the parameter list to a proxy server; and receiving, by the web browser, a content item to render in a content slot of the web page based on the proxy server determining an aggregate value of at least one parameter in the parameter list satisfies a predetermined threshold.
