Re: [FD] Obtaining location using Google maps & JavaScript

[Reed Black <reed@xxxxxxxxxxxxxx>]

Have you tested this?

The Google Maps page header includes "x-frame-options: SAMEORIGIN” which would 
prevent iframe embedding in every commonly used browser. But even if this 
control were not in place, browsers implement additional controls. Most 
significantly, if the page to be embedded in an iframe is on a remote domain, 
then the parent page is prevented from inspecting iframe content and metadata 
unless permissions are granted by the embedded page. Most modern browsers also 
block the embedded portion from html5 canvas reads. This means that even OCR of 
the rendered canvas should not work.
