if a website used an image to display any sensitive information, would it be possible to load the image into a html 5 canvas tag, get all the data from it and submit it your server? also, what if you used the canvas tag to pull in a form from another server, what would happen? would it be possible to convert the data back into text and manipulate it via js? thanks
