Abstract
A method and system to selectively secure the display of advertisements on web browsers. A method in accordance with an embodiment includes: defining a particular displayed area of the interpreted markup file; obtaining the DOM tree of the interpreted markup file, the DOM tree comprising parent and child nodes, each node being associated with displayable elements; identifying in the DOM tree a set of child nodes whose displayable elements comprise the particular displayed area; identifying in the DOM tree a first parent node comprising the set of child nodes; converting displayable elements associated with the identified first parent node to an image; generating a second parent node comprising the image; and modifying the DOM tree into a modified DOM tree by deleting the identified set of child nodes and by replacing the identified first parent node by the second parent node.
