Abstract
Methods and apparatus for network security content-checking, in particular simplifying the critical element of a content-checker so that it can be trusted and implemented in hardware logic. A method comprises determining whether a digitally encoded document contains any embedded documents; content-checking, by means of at least one hard-ware-implemented content-checker, at least one of the embedded documents separately from those parts of the digitally encoded document within which it was embedded; and releasing a version of the digitally encoded document responsive to the content-checking.
