Patent attributes
A computer-implemented method includes receiving content and annotation information that describe a structure of the content, the annotation information having been previously generated by a sub-system that is separate from a content transformation sub-system and at a time before the content was requested to be served; interpreting the annotation information to generate transcoding rules that identify one or more portions of the received content to be transcoded in serving the content; applying the transcoding rules to the content to change the content in a manner that interferes with an ability of malware on a client device to interfere with operation of the content; and providing the transcoded content to a client device that requested the content.
