1. A system comprising: identification logic adapted to identify a searchable segment of a document, the searchable segment being identified in accordance with an identification criterion; image-generation logic adapted to generate a first image from the searchable segment, the first image being a substantially unsearchable representation of the searchable segment; and substitution logic adapted to substitute the searchable segment with a reference to the generated first image, such that the reference facilitates display of the generated first image to a user in substitution for the identified searchable segment in the document, wherein upon a user selection of the displayed generated first image, the substitution logic is configured to provide the searchable segment for editing, wherein, upon providing the searchable segment, the user may edit the searchable segment and upon completion of editing of the searchable segment, the image-generation logic generates a second image that is a substantially unsearchable representation of the edited searchable segment.
