Maintaining the integrity and security of engineering drawings is a major concern to all parties involved in a project. The fear of unauthorized changes to a drawing made after issue has made many an engineer lose sleep.

Architecture and engineering law requires that drawings be sealed and signed by the engineer in charge of producing the drawings. In the digital world, an image of a seal and a signature is simply an image; anyone with a simple scanner can easily scan and reuse such an image for a set of plans.
