18. A method of a networked device comprising: associating with a client device executing a sandboxed application by way of a sandbox reachable service executing on the networked device using a communication provided by the networked device, the client device constraining an executable environment in a security sandbox and executing the sandboxed application in the constrained executable environment; applying an automatic content recognition algorithm to determine a content identifier of an audio-visual data; associating the content identifier with an advertisement data based on a semantic correlation between a metadata of the advertisement data provided by a content provider and the content identifier; targeting the advertisement data at the client device based on the association of the content identifier with the advertisement data and the association between the client device and the networked device; and improving targeting of the advertisement data in accordance with the association between the client device and the networked device based on embedding a script is in at least one of the client device, a supply-side platform, and a data provider integrated with the supply side platform to enable execution of arbitrary cross-site scripts in the sandboxed application of the client device.

The method of claim 18 : wherein a cookie associated with the security sandbox is used to store a remote access token on a storage of the client device, wherein the remote access token identifies at least one of a set of communicable private IP addresses and hardware addresses associated with sandbox reachable services that previously operated on a common shared network with the client device, and the client device can communicate with the sandbox reachable services that previously operated on the common shared network through the remote access token.
